Release notes for ESAPI 2.2.1.0
Release date: 2020-July-12
Project leaders:
-Kevin W. Wall <[email protected]>
-Matt Seil <[email protected]>
Previous release: ESAPI 2.2.0.0, 2019-June-24
Executive Summary: Important Things to Note for this Release
------------------------------------------------------------
This is a minor release. It's main purpose was to update dependencies to eliminate potential vulnerabilities arising from dependencies with known CVEs. See the section "Changes requiring special attention" below for additional details.
Also special props to Bill Sempf for stepping up and volunteering to prepare the initial cut of these release notes. Had he not done so, this release either would not have release notes or it would have been delayed another 6 months while I procrastinated further with various distractions. (Squirrel!)

-----------------------------------------------------------------------------
Changes Requiring Special Attention
-----------------------------------------------------------------------------
The new default ESAPI logger is JUL (java.util.logging packages) and we have deprecated the use of Log4J 1.x because we now support SLF4J and Log4J 1.x is way past its end-of-life. We did not want to make SLF4J the default logger (at least not yet) as we did not want to have the default ESAPI use require additional dependencies. However, SLF4J is likely to be the future choice, at least once we start on ESAPI 3.0. A special shout-out to Jeremiah Stacey for making this possible by re-factoring much of the ESAPI logger code. Note, the straw that broke the proverbial camel's back was the announcement of CVE-2019-17571 (rated Critical), for which there is no fix available and likely will never be.
Related to that CVE and how it affects ESAPI, be sure to read
https://github.com/ESAPI/esapi-java-legacy/blob/develop/documentation/ESAPI-security-bulletin2.pdf
which describes CVE-2019-17571, a deserialization vulnerability in Log4J 1.2.17. ESAPI is not affected by this (even if you chose to use Log4J 1 as you default ESAPI logger). This security bulletin describes why this CVE is not exploitable as used by ESAPI.
Notable dependency updates (excludes those only used with JUnit tests):
antiSamy 1.5.8 -> 1.5.10
batik-css 1.11 -> 1.13
commons-beansutil 1.9.3 -> 1.9.4
slf4j-api 1.7.26 -> 1.7.30
Finally, while ESAPI still supports JDK 7 (even though that too is way past end-of-life), the next ESAPI release will move to JDK 8 as the minimal baseline. (We already use Java 8 for development but still to Java 7 source and runtime compatibility.)
-----------------------------------------------------------------------------
Known Issues / Problems
-----------------------------------------------------------------------------
If you use Java 7 (the minimal Java baseline supported by ESAPI) and try to run 'mvn test' there is one test that fails. This test passes with Java 8. The failing test is:
[ERROR] Tests run: 5, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.203 s
<<< FAILURE! - in org.owasp.esapi.crypto.SecurityProviderLoaderTest
[ERROR] org.owasp.esapi.crypto.SecurityProviderLoaderTest.testWithBouncyCastle
Time elapsed: 0.116 s <<< FAILURE!
java.lang.AssertionError: Encryption w/ Bouncy Castle failed with
EncryptionException for preferred cipher transformation; exception was:
org.owasp.esapi.errors.EncryptionException: Encryption failure (unavailable
cipher requested)
at
org.owasp.esapi.crypto.SecurityProviderLoaderTest.testWithBouncyCastle(Security
ProviderLoaderTest.java:133)
I will spare you all the details and tell you that this has to do with Java 7 not being able to correctly parse the signed Bouncy Castle JCE provider jar. More details are available at:
https://www.bouncycastle.org/latest_releases.html
and
https://github.com/bcgit/bc-java/issues/477
I am sure that there are ways of making Bouncy Castle work with Java 7, but since ESAPI does not rely on Bouncy Castle (it can use any compliant JCE provider), this should not be a problem. (It works fine with the default SunJCE provider.) If it is important to get the BC provider working with the ESAPI Encryptor and Java 7, then open a GitHub issue and we will take a deeper look at it and see if we can suggest something.
Another problem is if you run 'mvn test' from the 'cmd' prompt (and possibly PowerShell as well), you will get intermittent failures (generally between 10-25% of the time) at arbitrary spots. If you run it again without any changes it will work fine without any failures. We have discovered that it doesn't seem to fail if you run the tests from an IDE like Eclipse or if you redirect both stdout and stderr to a file; e.g.,
C:\code\esapi-java-legacy> mvn test >testoutput.txt 2>&1
We do not know the reason for these failures, but only that we have observed them on Windows 10. If you see this error, please do NOT report it as a GitHub issue unless you know a fix for it.
*** IMPORTANT WORKAROUND for 2.2.1.0 ESAPI Logging ***
Lastly, if you try to use the new ESAPI 2.2.1.0 logging, you will notice that you need to change ESAPI.Logger and also possibly provide some other logging properties as well. This is because the logger packages were reorganized to improve maintainability, but we failed to mention it. To use ESAPI logging in ESAPI 2.2.1.0 (and later), you MUST set the ESAPI.Logger property to one of:
org.owasp.esapi.logging.java.JavaLogFactory - To use the new default, java.util.logging (JUL)
org.owasp.esapi.logging.log4j.Log4JLogFactory - To use the end-of-life Log4J 1.x logger
org.owasp.esapi.logging.slf4j.Slf4JLogFactory - To use the new (to release 2.2.0.0) SLF4J logger
In addition, if you wish to use JUL for logging, you *must* supply an "esapi-java-logging.properties" file in your classpath. Unfortunately, we failed to drop add that to the ESAPI configuration jar under the GitHub 'Releases', so this file has been added explicitly to the 2.2.1.0 release 'Assets' for this release (for details, see https://github.com/ESAPI/esapi-java-legacy/releases/esapi-2.2.1.0). Even worse, there was a logic error in the static initializer of JavaLogFactory (now fixed in the 2.2.1.1 patch release) that causes a NullPointerException to be thrown so that the message about the missing "esapi-java-logging.properties" file was never seen.
If you are using JavaLogFactory or Slf4JLogFactory, you will also want to ensure that you have the following ESAPI logging properties set to get the logs to appear what you are used to with Log4J 1.x logging:
# Set the application name if these logs are combined with other applications
Logger.ApplicationName=ExampleApplication
# If you use an HTML log viewer that does not properly HTML escape log data, you can set LogEncodingRequired to true
Logger.LogEncodingRequired=false
# Determines whether ESAPI should log the application name. This might be clutter in some single-server/single-app environments.
Logger.LogApplicationName=true
# Determines whether ESAPI should log the server IP and port. This might be clutter in some single-server environments.
Logger.LogServerIP=true
# LogFileName, the name of the logging file. Provide a full directory path (e.g., C:\\ESAPI\\ESAPI_logging_file) if you
# want to place it in a specific directory.
Logger.LogFileName=ESAPI_logging_file
# MaxLogFileSize, the max size (in bytes) of a single log file before it cuts over to a new one (default is 10,000,000)
Logger.MaxLogFileSize=10000000
# Determines whether ESAPI should log the user info.
Logger.UserInfo=true
# Determines whether ESAPI should log the session id and client IP.
Logger.ClientInfo=true
See GitHub issue #560 for additional details.

Acknowledgments:
Release notes written by Bill Sempf ([email protected]), but please direct any communication to the project leaders.
Special shout-outs to:
Jeremiah Stacey (jeremiahjstacey) -- All around ESAPI support and JUnit test case developer extraordinaire and for refactoring ESAPI loggers.
Dave Wichers (davewichers) - for several extremely useful pom.xml improvements.
Bill Sempf (sempf) -- for these release notes. Awesome job, Bill. I owe you a brew.
Chamila Wijayarathna <[email protected]> and Nalin A. G. Arachchilage <[email protected]> for their authorship and subsequent extensive discussion of their paper "Fighting Against XSS Attacks: A Usability Evaluation of OWASP ESAPI Output Encoding" (https://scholarspace.manoa.hawaii.edu/bitstream/10125/60167/0727.pdf). Their paper and their willingness to engage with me to discuss it was what led to the (hopefully) improved Javadoc for the ESAPI Encoder interface.
And lastly a special thanks to first-time contributors Michael-Ziluck, wiiitek, and HJW8472.
Thanks you all for your time and effort to ESAPI and making it a better project. And if I've missed any, my apologies; let me know and I will correct it.
A special thanks to the ESAPI community from the ESAPI project co-leaders:
Kevin W. Wall (kwwall) <== The irresponsible party for these release notes!
