Release notes for ESAPI 2.5.1.0

Previous release: ESAPI 2.5.0.0, 2022-07-20


Executive Summary: Important Things to Note for this Release
------------------------------------------------------------
This is a patch release with the primary intent of updating some dependencies, some which addressed known vulnerabilities in these dependencies, but which we do not believe were exploitable via ESAPI. The major updates are:
* Updates to latest versions of direct dependencies, including:
- An update to AntiSamy: 1.7.0 --> 1.7.2
- An update to SLFJ4 API: 1.7.36 --> 2.0.4 (Note: 2.0.5 is available and likely would would result in "convergence" issues with the version AntiSamy 1.7.2 pulls in)
* A new codec (org.owasp.esapi.codecs.JSONCodec) is provided that provides JSON output encoding as per section 7 of RFC 8259. It is made available via Encoder.encodeForJSON(). (Note unlike other encoders, there is no corresponding decoder (i.e., decodeForJSON()) made available. Since that would normally be done by your JavaScript code, it wasn't deemed essential.

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 we have finally removed the Log4J 1.2.17 dependency in ESAPI 2.5.0.0.

Any remaining flagged vulnerabilities (e.g., CVE-2020-7791 for transitive dependency batik-i18n-1.14) are believed to be false postives.

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 JDK Support Announcement
* ESAPI 2.3.0.0 was the last Java release to support Java 7. ESAPI 2.4.0 requires using Java 8 or later. See the ESAPI 2.4.0.0 release notes (https://github.com/ESAPI/esapi-java-legacy/blob/develop/documentation/esapi4java-core-2.4.0.0-release-notes.txt) for details as to the reason.
- This means if your project requires Java 7, you must use ESAPI 2.3.0.0 or earlier.

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 haveing first been deprecated.) Thus, you only choice of 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 implemmentation)
* Set ESAPI.Logger=org.owasp.esapi.logging.slf4j.Slf4JLogFactory in your ESAPI.properties file.
* 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

CHANGELOG: Create your own. May I suggest:

git log --stat --since=2022-07-20 --reverse --pretty=medium

which will show all the commits since just after the previous (2.5.0.0) 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'

Acknowledgments:
Another hat tip to Dave Wichers and the AntiSamy crew for promptly releasing AntiSamy 1.7.2. And thanks to Matt Seil, Jeremiah Stacey, and all the ESAPI users who make this worthwhile. This is for you.

A special thanks to the ESAPI community from the ESAPI project co-leaders:
