Release notes for ESAPI 2.5.0.0
Release date: 2022-07-20
Project leaders:
-Kevin W. Wall <kevin.w.wall@gmail.com>
-Matt Seil <matt.seil@owasp.org>
Previous release: ESAPI 2.4.0.0, 2022-04-24
Executive Summary: Important Things to Note for this Release
------------------------------------------------------------
In addition to this summary, please also be sure to thoroughly read the section "Changes Requiring Special Attention", below.
Major changes:
Logging:
The major change in ESAPI 2.5.0.0 is the removal of the Log4J 1 dependency (specifically, log4j-1.2.17). It has been removed because in accordance with the ESAPI deprecation policy (see the README.md file), the Log4J supported logger has been deprecated for 2 years.
For those of you using a Software Configuration Analysis (SCA) services such as Snyk, BlackDuck, Veracode SourceClear, OWASP Dependency Check, etc., you will notice that the 4 Log4J 1.x related CVEs are no longer flagged. This is because of removal of the Log4J 1.2.17 dependency.
Any remaining flagged vulnerabilities (e.g., CVE-2020-7791 for transitive dependency batik-i18n-1.14) are believed to be false positives.
You are encouraged to review the vulnerability analysis written up in https://github.com/ESAPI/esapi-java-legacy/blob/develop/Vulnerability-Summary.md and email us or contact us in our GitHub Discussions page if you have questions.

Changes Requiring Special Attention
-----------------------------------------------------------------------------
Important ESAPI Logging Changes
* Since ESAPI 2.5.0.0, support for logging directly via Log4J 1 has been removed. (This was two years after it having first been deprecated.) Thus, your only choice for ESAPI logging are:
- java.util.logging (JUL), which as been the default since ESAPI 2.2.1.0.
* Set ESAPI.Logger=org.owasp.esapi.logging.java.JavaLogFactory in your ESAPI.properties file.
- SLF4J (which your choice of supported SLF4J logging implementation)
* Set ESAPI.Logger=org.owasp.esapi.logging.slf4j.Slf4JLogFactory in your ESAPI.properties file.
* Create your own custom logger.
* Logger configuration notes - If you are migrating from prior to ESAPI 2.2.1.1, you will need to update your ESAPI.properties file as logging-related configuration as per the ESAPI 2.2.1.1 release notes, which may be found at:
https://github.com/ESAPI/esapi-java-legacy/blob/develop/documentation/esapi4java-core-2.2.1.1-release-notes.txt#L39-L78
If you use ESAPI 2.5.0.0 or later, you will get an ClassNotFoundException as the root cause if you still have your ESAPI.Logger property set to use Log4J because the org.owasp.esapi.logger.log4j.Log4JFactory class has been completely removed from the ESAPI jar. If you are dead set on continuing to use Log4J 1, you ought to be able to do so via SLF4J. The set up for Log4J 1 (which has not be tested), should be similar to configure ESAPI to use SLF4J with Log4J 2 as described here:
https://github.com/ESAPI/esapi-java-legacy/wiki/Using-ESAPI-with-SLF4J#slf4j-using-log4j-2x
Potentially Breaking Changes in AntiSamy 1.7.0
* This version of ESAPI has upgraded to the latest version of AntiSamy (1.7.0 at the time of our release). AntiSamy 1.7.0 has some breaking changes to its SDK and the way that it processes AntiSamy policy files, of which the antisamy-esapi.xml file, included in our esapi-2.5.0.0-configuration.jar found at https://github.com/ESAPI/esapi-java-legacy/releases/download/esapi-2.5.0.0/esapi-2.4.0.0-configuration.jar, is the one we include.
* None of the AntiSamy SDK changes affected how ESAPI, in its default configuration, uses it, but you may be affected if you have customized your AntiSamy policy file. If your regression tests fail when you upgrade to ESAPI 2.5.0.0 sand they seem to be related to AntiSamy, then please review https://github.com/nahsra/antisamy/blob/main/README.md#important---api-breaking-changes-in-170. Also, as a temporary workaround, you could do something like this (in Maven, but similar exclusion can be done with Gradle) to allow you time to correct your customized AntiSamy policy file:
<dependency>
<groupId>org.owasp.esapi</groupId>
<artifactId>esapi</artifactId>
<version>2.5.0.0</version>
<exclusions>
<!-- Exclude breaking version of AntiSamy 1.7.0 to allow time to fix our AntiSamy policy file, antisamy-esapi.xml -->
<exclusion>
<groupId>org.owasp.antisamy</groupId>
<artifactId>antisamy</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.owasp.antisamy</groupId>
<artifactId>antisamy</artifactId>
<version>1.6.8</version>
</dependency>
Indeed the only change that we had to make is to alter a JUnit test that was intended to ensure that invalid AntiSamy policy files could be disabled by setting
Policy.setSchemaValidation(false);
before processing any AntiSamy policy file not conforming to its schema. This specific (previously deprecated) method was removed in AntiSamy 1.7.0 so the schema validation checks can no longer be ignored. (And hence the reason for the workaround noted above.)
Instead, we simply changed the JUnit test to check that the expected AntiSamy org.owasp.validator.html.PolicyException class is thrown when the invalid policy file is loaded.
-----------------------------------------------------------------------------
Remaining Known Issues / Problems
-----------------------------------------------------------------------------
* 'mvn site' fails to build these two reports:
"Tag reference" report --- maven-taglib-plugin:2.4:tagreference
"Taglibdoc documentation" report --- maven-taglib-plugin:2.4:taglibdoc
Thus no tag library documentation will be generated. :-(
We are attempting to find a solution, but on the surface, it seems like the maven-taglib-plugin does not play nicely with versions of Java after Java 6. (So, this probably has been happening for a while and we just noticed it.)
* We have had to suppress CVE-2017-10355, related to the transitive dependency xercesImpl-2.12.2.jar via antisamy-1.7.0.jar. It is the same jar that has been used for the past 2 years but the CVE just started popping up now, apparently because of changes to Sonatype's OSS Index. More details are available in the OWASP Dependency Check suppression rules contained in the 'suppressions.xml' file. Note that other SCA tools such as Snyk or GitHub Dependabot are not presently reporting it, but it bears watching.
* Trying to run 'mvn test' with Java 11 or later results in multiple errors in maven-surefire-plugin, so for now, that should be avoided. We think we may have a solution, but at this point, it is too late to test for this release.
* No others problems are known, other than the remaining open issues on GitHub.
-----------------------------------------------------------------------------
Other changes in this release, some of which not tracked via GitHub issues
-----------------------------------------------------------------------------
* Minor updates to README.md file with respect to version information.

Developer Activity Report (Changes between release 2.4.0.0 and 2.5.0.0, i.e., between 2022-04-24 and 2022-07-20)
Generated manually (this time) -- all errors are the fault of kwwall and his inability to do simple arithmetic.
#
# 34 PRs merged since ESAPI 2.4.0.0 release
# Apparent disparement in the figures below may be explained by serveral things:
# * My failure to do proper counting and basic arithmetic after 4 hours of tweak release notes.
# * Different basis for calculations:
# - Figures here may not agree with generated Change Log Report, which is date-based, as some commits included in this release were prior to ESAPI 2.4.0.0 and thus not included in the Change Log Report.
# - Some commits are done without PRs. Generally, we don't require PRs when we don't require code reviews. That generally is restricted to documenation files, making simple config file changes, and correcting obvious typos. Commits without PRs are resricted to the 3 ESAPI core team members.
# - Sometimes in a PR, multiple commits touch a file multiple times so we count those files once for each commit.

CHANGELOG: Create your own. May I suggest:
git log --stat --since=2022-04-24 --reverse --pretty=medium
which will show all the commits since just after the previous (2.4.0.0) release.
Alternately, you can download the most recent ESAPI source and run
mvn site
which will create a CHANGELOG file named 'target/site/changelog.html'
