== OWASP ModSecurity Core Rule Set (CRS) CHANGES ==
== Report Bugs/Issues to GitHub Issues Tracker or the mailinglist ==
* https://github.com/coreruleset/coreruleset/issues
or the CRS Google Group at
* https://groups.google.com/a/owasp.org/forum/#!forum/modsecurity-core-rule-set-project
== Version 3.3.4 - 2022-09-20 ==
Fixes and improvements:
* Fix a regression in our former release, with the impact that some Paranoia Level 2 rules would activate even when running in Paranoia Level 1. (Simon Studer, Walter Hop)
== Version 3.3.3 - 2022-09-19 ==
Important changes:
* This update requires ModSecurity version 2.9.6 or 3.0.8 (or an updated version with backports of the security fixes in these versions) or a compatible engine supporting these changes. If you do not upgrade ModSecurity, the file REQUEST-922-MULTIPART-ATTACK.conf will cause ModSecurity to fail to start. In that case, you can temporarily delete that file. However, you will be missing protection from these rules. Therefore, we recommend upgrading your ModSecurity or other engine instead.
* By default, the request headers "Accept-Charset" and "Content-Encoding" are now blocked to prevent a WAF bypass. Especially the "Accept-Charset" header may be in use by clients. If you need to serve clients that send this header, uncomment and edit rule 900250 in crs-setup.conf.
Fixes and improvements:
* Fix CVE-2022-39955 Multiple charsets defined in Content-Type header (Jan Gora)
* Fix CVE-2022-39956 Content-Type or Content-Transfer-Encoding MIME header fields abuse (Jan Gora, Felipe Zipitria)

* Fix CVE-2022-39958 Small range header leading to response rule set bypass (Hussein Daher, Christian Folini)
* Fix MIME header abuse via _charset_ field (Jan Gora, Felipe Zipitria)
* Fix bypass using deflated request body (Karel Knibbe)
* Fix request body partial rule set bypass via Content-Type "text/plain" (Pinaki Mondal, Andrea Menin)
* Fix XML Body Parser abuse for non-XML request bodies (Jan Gora)
* Fix body processor bypass by content-type outside the mime type declaration (Jan Gora, Simon Studer, Ervin Hegedus)
== Version 3.3.2 - 2021-06-30 ==
Fixes and improvements:
* Fix CVE-2021-35368 WAF bypass using pathinfo (Christian Folini)
== Version 3.3.0 - 2020-07-01 ==
Important changes:
* The format of crs-setup.conf variable "tx.allowed_request_content_type" has been changed to be more in line with the other variables. If you have overridden this variable, please see the example in crs-setup.conf for the new separator to use.

== Version 2.0.5 - 2010-02-01 ==
Improvements:
* Removed previous 10 config files as they may conflict with local customized Mod configs.
* Added a new 10 config file that allows the user to globally set TX variables to turn on/off
PARANOID_MODE inspection, set anomaly score levels and http policies.
Must have ModSecurity 2.5.12 to use the macro expansion in numeric operators.
* Added Rule Logic and Reference links to rules descriptions.
* Added Rule IDs to all rules.
* Added tag data mapping to new OWASP Top 10 and AppSensor Projects, WASC Threat Classification
* Removed Apache limit directives from the 23 file
* Added macro expansion to 23 file checks.
* Added @pmFromFile check to 35 bad robots file
* Added malicious UA strings to 35 bad robots check
* Created an experimental rules file
* Updated HTTP Parameter Pollution (HPP) rule logic to concat data into a TX variable for inspection
* Removed TX inspections for generic attacks and reverted to standard ARGS inspection
https://www.modsecurity.org/tracker/browse/MODSEC-120
* Updated the variable list for standard inspections (ARGS|ARGS_NAMES|XML:/*) and moved the other
variables to the PARANOID list (REQUEST_URI|REQUEST_BODY|REQUEST_HEADERS|TX:HPP_DATA)
* Moved converted ET Snort rules to the /optional_rules directory
* Created a new Header Tagging ruleset (optional_rules) that will add matched rule data to the
request headers.

Identified by SOGETI ESEC R&D
Bug Fixes:
* Removed Non-numeric Rule IDs
https://www.modsecurity.org/tracker/browse/CORERULES-28
* Updated the variable list on SQLi rules.
* Fixed outbound @pmFromFile action from allow to skipAfter to allow for outbound anomaly scoring
and blocking
== Version 2.0.4 - 2009-11-30 ==
Improvements:
* Updated converted PHPIDS signatures (https://svn.php-ids.org/svn/trunk/lib/IDS/default_filter.xml)
* Updated PHPIDS rules logic to first search for payloads in ARGS and then if there is no match found
then search more generically in request_body|request_uri_raw
* Updated PHPIDS rules logic to only set TX variables and to not log. This allows for more clean
exceptions in the 48 file which can then expire/delete false positive TX matches and adjust the
anomaly scores. These rules will then inspect for any TX variables in phase:5 and create appropriate
alerts for any variable matches that exist.
Bug Fixes:
* Added Anomaly Score check to the 60 correlation file to recheck the anomaly score at the end of
phase:4 which would allow for blocking based on information leakage issues.
== Version 2.0.3 - 2009-11-05 ==
Improvements:
* Updated converted PHPIDS signatures (https://svn.php-ids.org/svn/trunk/lib/IDS/default_filter.xml)

== Version 2.0.1 - 2009-08-07 ==
Improvements:
* Updated the transformation functions used in the XSS/SQLi rules to improve performance
https://www.modsecurity.org/tracker/browse/CORERULES-10
* Updated the variable/target list in the XSS rules
https://www.modsecurity.org/tracker/browse/CORERULES-11
* Added XSS Filters from IE8
https://www.modsecurity.org/tracker/browse/CORERULES-12
Bug Fixes:
* Rule 958297 - Fixed unescaped double-quote issue in Comment SPAM UA rule.
https://www.modsecurity.org/tracker/browse/CORERULES-9
== Version 2.0.0 - 2009-07-29 ==
New Rules & Features:
* Fine Grained Policy
The rules have been split to having one signature per rule instead of having
all signatures combined into one optimized regular expression.
This should allow you to modify/disable events based on specific patterns
instead of having to deal with the whole rule.
* Converted Snort Rules
Emerging Threat web attack rules have been converted.
http://www.emergingthreats.net/
* Anomaly Scoring Mode Option
The rules have been updated to include anomaly scoring variables which allow
you to evaluate the score at the end of phase:2 and phase:5 and decide on what
logging and disruptive actions to take based on the score.
* Correlated Events
There are rules in phase:5 that will provide some correlation between inbound
events and outbound events and will provide a result of successful atttack or
attempted attack.
* Updated Severity Ratings
The severity ratings in the rules have been updated to the following:
- 0: Emergency - is generated from correlation where there is an inbound attack and
an outbound leakage.
- 1: Alert - is generated from correlation where there is an inbound attack and an
outbound application level error.
- 2: Critical - is the highest severity level possible without correlation. It is
normally generated by the web attack rules (40 level files).
- 3: Error - is generated mostly from outbound leakabe rules (50 level files).
- 4: Warning - is generated by malicious client rules (35 level files).
- 5: Notice - is generated by the Protocol policy and anomaly files.
- 6: Info - is generated by the search engine clients (55 marketing file).
* Updated Comment SPAM Protections
Updated rules to include RBL lookups and client fingerprinting concepts from
Bad Behavior (www.bad-behavior.ioerror.us)
* Creation of Global Collection
Automatically create a Global collection in the *10* config file. Other rules
can then access it.
* Use of Block Action
Updated the rules to use the "block" action. This allows the Admin to globally
set the desired block action once with SecDefaultAction in the *10* config file
rather than having to edit the disruptive actions in all of the rules or for
the need to have multiple versions of the rules (blocking vs. non-blocking).
* "Possible HTTP Parameter Pollution Attack: Multiple Parameters with the same Name."
http://tacticalwebappsec.blogspot.com/2009/05/http-parameter-pollution.html
* Added new generic RFI detection rules.
http://tacticalwebappsec.blogspot.com/2009/06/generic-remote-file-inclusion-attack.html
* "Possibly malicious iframe tag in output" (Rules 981001,981002)
Planting invisible iframes in a site can be used by attackers to point users
from the victim site to their malicious site. This is actually as if the
user was visiting the attacker's site himself, causing the user's browser to
process the content in the attacker's site.
New Events:
* Rule 960019 - Expect Header Not Allowed.
* Rule 960020 - Pragma Header Requires Cache-Control Header
* Rule 958290 - Invalid Character in Request - Browsers should not send the (#) character
as it is reserved for use as a fragment identifier within the html page.
* Rule 958291 - Range: field exists and begins with 0.
* Rule 958292 - Invalid Request Header Found.
* Rule 958293 - Lowercase Via Request Header Found.
* Rule 958294 - Common SPAM Proxies found in Via Request Header.
* Rule 958295 - Multiple/Conflicting Connection Header Data Found.
* Rule 958296 - Request Indicates a SPAM client accessed the Site.
* Rule 958297 - Common SPAM/Email Harvester crawler.
* Rule 958298 - Common SPAM/Email Harvester crawler
Bug Fixes:
* Rule 950107 - Split the rule into 2 separate rules to factor in the
Content-Type when inspecting the REQUEST_BODY variable.
* Rule 960017 - Bug fix for when having port in the host header.
* Rule 960014 - Bug fix to correlate the SERVER_NAME variable.
* Rule 950801 - Increased the logic so that the rule will only run if the web site
uses UTF-8 Encoding.
* Rules 999210,999211 - Bug fix to move ctl actions to last rule, add OPTIONS and
allow the IPv6 loopback address
* Rule 950117 - Updated the RFI logic to factor in both a trailing "?" in the ARG
and to identify offsite hosts by comparing the ARG URI to the Host
header. Due to this rule now being stronger, moved it from optional
tight security rule to *40* generic attacks file.
Other Fixes:
* Added more HTTP Protocol violations to *20* file.
* Set the SecDefaultAction in the *10* config file to log/pass (This was the
default setting, however this sets it explicitly.
* Added SecResponseBodyLimitAction ProcessPartial to the *10* config file. This
was added so that when running the SecRuleEngine in DetectionOnly mode, it will
not deny response bodies that go over the size restrictions.
* Changed SecServerSignature to "Apache/1.3.28"
* Fixed the use of SkipAfter and SecMarkers to make it consistent. Now have
BEGIN and END SecMarkers for rule groups to more accurately allow moving to
proper locations.
* Fixed the @pm/@pmFromFile pre-qualifier logic to allow for operator inversion.
This removes the need for some SecAction/SkipAfter rules.
* Updated rule formatting to easily show rule containers (SecMarkers, pre-qualifier
rules and chained rules).
== Version 1.6.1 - 2008-04-22 ==
* Fixed a bug where phases and transformations where not specified explicitly
in rules. The issue affected a significant number of rules, and we strongly
recommend to upgrade.
== Version 1.6.0 - 2008-02-19 ==
New Rulesets & Features:
* 42 - Tight Security
This ruleset contains currently 2 rules which are considered highly prone
to FPs. They take care of Path Traversal attacks, and RFI attacks. This
ruleset is included in the optional_rulesets dir
* 42 - Comment Spam
Comment Spam is used by the spammers to increase their rating in search
engines by posting links to their site in other sites that allow posting
of comments and messages. The rules in this ruleset will work against that.
(Requires ModSecurity 2.5)
* Tags
A single type of attack is often detected by multiple rules. The new alert
classification tags solve this issue by providing an alternative alert type
indication and can serve for filtering and analysis of audit logs.
The classification tags are hierarchical with slashes separating levels.
Usually there are two levels with the top level describing the alert group
and the lower level denoting the alert type itself, for example:
WEB_ATTACK/SQL_INJECTION.
False Positives Fixes:
* Rule 960903 - Moved to phase 4 instead of 5 to avoid FPs
* Rule 950107 - Will look for invalid url decoding in variables that are not
automatically url decoded
Additional rules logic:
* Using the new "logdata" action for logging the matched signature in rules
* When logging an event once, init the collection only if the alert needs to log
* Using the new operator @pm as a qualifier before large rules to enhance
performance (Requires ModSecurity 2.5)
* SQL injection - A smarter regexp is used to detect 1=1,2=2,etc.. and not
only 1=1. (Thanks to Marc Stern for the idea)
* New XSS signatures - iframe & flash XSS
== Version 1.5.1 - 2007-12-06 ==
False Positives Fixes:
* Protocol Anomalies (file 21) - exception for Apache SSL pinger (Request: GET /)
New Events:
* 960019 - Detect HTTP/0.9 Requests
HTTP/0.9 request are not common these days. This rule will log by default,
and block in the blocking version of file 21
Other Fixes:
* File 40, Rules 950004,950005 - Repaired the correction for the double
url decoding problem
* File 55 contained empty regular expressions. Fixed.
== Version 1.5 - 2007-11-23 ==
New Rulesets:
* 23 - Request Limits
"Judging by appearances". This rulesets contains rules blocking based on
the size of the request, for example, a request with too many arguments
will be denied.
Default policy changes:
* XML protection off by default
* BLOCKING dir renamed to optional_rules
* Ruleset 55 (marketing) is now optional (added to the optional_rules dir)
* Ruleset 21 - The exception for apache internal monitor will not log anymore
New Events:
* 960912 - Invalid request body
Malformed content will not be parsed by modsecurity, but still there might
be applications that will parse it, ignoring the errors.
* 960913 - Invalid Request
Will trigger a security event when request was rejected by apache with
code 400, without going through ModSecurity rules.
Additional rules logic:
* 950001 - New signature: delete from
* 950007 - New signature: waitfor delay
False Positives Fixes:
* 950006 - Will not be looking for /cc pattern in User-Agent header
* 950002 - "Internet Explorer" signature removed
* Double decoding bug used to cause FPs. Some of the parameters are already
url-decoded by apache. This caused FPs when the rule performed another
url-decoding transformation. The rules have been split so that parameters
already decoded by apache will not be decoded by the rules anymore.
* 960911 - Expression is much more permissive now
* 950801 - Commented out entirely. NOTE: If your system uses UTF8 encoding,
then you should uncomment this rule (in file 20)
version 1.4.3 - 2007-07-21
New Events:
* 950012 - HTTP Request Smuggling
For more info on this attack:
http://www.cgisecurity.com/lib/HTTP-Request-Smuggling.pdf
* 960912 - Invalid request body
Malformed content will not be parsed by modsecurity, but still there might
be applications that will parse it, ignoring the errors.
* 960913 - Invalid Request
Will trigger a security event when request was rejected by apache with
code 400, without going through ModSecurity rules.
False Positives Fixes:
* 950107 - Will allow a % sign in the middle of a string as well
* 960911 - A more accurate expression based on the rfc:
http://www.ietf.org/rfc/rfc2396.txt
* 950015 - Will not look for http/ pattern in the request headers
Additional rules logic:
* Since Apache applies scope directives only after ModSecurity phase 1
this directives cannot be used to exclude phase 1 rules. Therefore
we moved all inspection rules to phase 2.
version 1.4 build 2 - 2007-05-17
New Feature:
* Search for signatures in XML content
XML Content will be parsed and ispected for signatures
New Events:
* 950116 - Unicode Full/Half Width Abuse Attack Attempt
Full-width unicode can by used to bypass content inspection. Such encoding will be forbidden
http://www.kb.cert.org/vuls/id/739224
* 960911 - Invalid HTTP request line
Enforce request line to be valid, i.e.: <METHOD> <path> <HTTP version>
* 960904 - Request Missing Content-Type (when there is content)
When a request contains content, the content-type must be specified. If not, the content will not be inspected
* 970018 - IIS installed in default location (any drive)
Log once if IIS in installed in the /Inetpub directory (on any drive, not only C)
* 950019 - Email Injection
Web forms used for sending mail (such as "tell a friend") are often manipulated by spammers for sending anonymous emails
Regular expressions fixes:
* Further optimization of some regular expressions (using the non-greediness operator)
The non-greediness operator, <?>, prevents excessive backtracking
FP fixes:
* Rule 950107 - Will allow a parameter to end in a % sign from now on
version 1.4 - 2007-05-02
New Events:
* 970021 - WebLogic information disclosure
Matching of "<title>JSP compile error</title>" in the response body, will trigger this rule, with severity 4 (Warning)
* 950015,950910,950911 - HTTP Response Splitting
Looking for HTTP Response Splitting patterns as described in Amit Klein's excellent white paper:
http://www.packetstormsecurity.org/papers/general/whitepaper_httpresponse.pdf
ModSecurity does not support compressed content at the moment. Thus, the following rules have been added:
* 960902 - Content-Encoding in request not supported
Any incoming compressed request will be denied
* 960903 - Content-Encoding in response not supported
An outgoing compressed response will be logged to alert, but ONLY ONCE.
False Positives Fixes:
* Removed <.exe>,<.shtml> from restricted extensions
* Will not be looking for SQL Injection signatures <root@>,<coalesce> in the Via request header
* Excluded Referer header from SQL injection, XSS and command injection rules
* Excluded X-OS-Prefs header from command injection rule
* Will be looking for command injection signatures in
REQUEST_COOKIES|REQUEST_COOKIES_NAMES instead of REQUEST_HEADERS:Cookie.
* Allowing charset specification in the <application/x-www-form-urlencoded> Content-Type
Additional rules logic:
* Corrected match of OPTIONS method in event 960015
* Changed location for event 960014 (proxy access) to REQUEST_URI_RAW
* Moved all rules apart from method inspection from phase 1 to phase 2 -
This will enable viewing content if such a rule triggers as well as setting
exceptions using Apache scope tags.
* Added match for double quote in addition to single quote for <or x=x> signature (SQL Injection)
* Added 1=1 signature (SQL Injection)
version 1.3.2 build 4 2007-01-17
Fixed apache 2.4 dummy requests exclusion
Added persistent PDF UXSS detection rule
== Version 1.3.2 build 3 2007-01-10 ==
Fixed regular expression in rule 960010 (file #30) to allow multipart form data
content
== Version 1.3.2 - 2006-12-27 ==
New events:
* 960037 Directory is restricted by policy
* 960038 HTTP header is restricted by policy
Regular expressions fixes:
* Regular expressions with @ at end of beginning (for example "@import)
* Regular expressions with un-escaped "."
* Command Injections now always require certain characters both before and after the command. Important since many are common English words (finger, mail)
* The command injection wget is not searched in the UA header as it has different meaning there.
* LDAP Fixed to reduce FPs:
+ More accurate regular expressions
+ high bit characters not accpeted between signature tokens.
* Do not detect <?xml as a PHP tag in both PHP injection and PHP source leakage
* Removed Java from automation UA
* When validating encoding, added regexp based chained rule that accepts both %xx and %uxxxxx encoding bypassing a limitation of "@validateUrlEncoding"
Additional rules logic:
* Checks for empty headers in addition to missing ones (Host, Accept and User-Agent)
* OPTIONS method does not require an accept header.
* Apache keep alive request exception.
* PROPFIND and OPTIONS can be used without content-encoding (like HEAD and GET)
* Validate byte range checks by default only that no NULL char exists.
* Added CSS to allowed extensions in strict rule sets.
* Changed default action in file #50 to pass instead of deny.
* Moved IP host header from protocol violations to protocol anomalies.
Modified descriptions:
* 950107: URL Encoding Abuse Attack Attempt
* 950801: UTF8 Encoding Abuse Attack Attempt
* Added matched pattern in many events using capture and %{TX.0}
* Added ctl:auditLogParts=+E for outbound events and attacks to collect response.
== Version 1.2 - 2006-11-19 ==
Changes:
+ Move all events to the range of events allocated to Thinking Stone, now Breach
by prefixing all event IDs with "9".
+ Reverse severities to follow the Syslog format used by ModSecurity, now 1 is
the highest and 5 the lowest.
Bug fixes:
+ Removed quotes from list of mime types inspected on exit (directive
SecResponseBodyMimeType)
+ Corrected "cd .." signature. Now the periods are escaped.
+ Too many FPs with events 950903 & 950905. Commented them out until fixed.
== Version 1.1 - 2006-10-18 ==
Initial version
