How to Fix CVE-2021-32729
To remediate this vulnerability, upgrade all affected Xwiki platform security authentication script dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-security-authentication-script</artifactId>
<version>12.6.8</version>
</dependency><dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-security-authentication-script</artifactId>
<version>12.10.4</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.xwiki.platformHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2021-32729, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.xwiki.platformAnalyze the terminal output to locate any version of Xwiki platform security authentication script in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 12.6.8), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.xwiki.platform command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Note that any bruteforce attack on the authentication should be visible in the logs since the authentication failures are logged.\n\n### References\nhttps://jira.xwiki.org/browse/XWIKI-18276\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [Jira](http://jira.xwiki.org)\n* Email us at [the security mailing-list](mailto:security@xwiki.org)\n",
