How to Fix CVE-2023-49280

To remediate this vulnerability, upgrade all affected Application changerequest default dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.xwiki.contrib.changerequest:application-changerequest-default fixed: 1.10 
<dependency>
    <groupId>org.xwiki.contrib.changerequest</groupId>
    <artifactId>application-changerequest-default</artifactId>
    <version>1.10</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.xwiki.contrib.changerequest

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-49280, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.xwiki.contrib.changerequest

Analyze the terminal output to locate any version of Application changerequest default in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.10), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.xwiki.contrib.changerequest 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-522: Insufficiently Protected Credentials, where the product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. In Application changerequest default, 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.

Source Advisory Statement

### Impact Change request allows to edit any page by default, and the changes are then exported in an XML that anyone can download. So it's possible for an attacker to obtain password hash of users by performing edition of the user profiles and then downloading the XML that has been created. This is also true for any document that might contain password field and that a user can view. This vulnerability impacts all version of Change Request, but the impact depends on the rights that has been set on the wiki since it requires for the user to have the Change request right (allowed by default) and view rights on the page to target. Also the issue cannot be easily exploited in an automated way. ### Patches The patch consists in denying to users the right of editing pages that contains a password field with change request. It means that already existing change request for those pages won't be removed by the patch, administrators needs to take care of it. The patch is provided in Change Request 1.10, administrators should upgrade immediately. ### Workarounds It's possible to workaround the vulnerability by denying manually the Change request right on some spaces, such as XWiki space which will include any user profile by default. ### References * JIRA issue: https://jira.xwiki.org/browse/CRAPP-302 * Commit of the fix: https://github.com/xwiki-contrib/application-changerequest/commit/ff0f5368ea04f0e4aa7b33821c707dc68a8c5ca8 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:security@xwiki.org) ### Attribution Thanks Michael Hamann for the report.
