How to Fix CVE-2023-35157
To remediate this vulnerability, upgrade all affected Xwiki platform oldcore 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-oldcore</artifactId>
<version>14.10.6</version>
</dependency><dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-oldcore</artifactId>
<version>15.1-rc-1</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-2023-35157, 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 oldcore in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.10.6), 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.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. In Xwiki platform oldcore, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
