How to Fix CVE-2024-55924

To remediate this vulnerability, upgrade all affected Typo3/cms scheduler dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

typo3/cms-scheduler fixed: 11.5.42 
Upgrade typo3/cms-scheduler to 11.5.42
Verify Direct and Transitive Dependencies

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

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-55924, inspect your project dependencies for Typo3/cms scheduler:

inspect dependencies for typo3/cms-scheduler

Analyze the terminal output to locate any version of Typo3/cms scheduler in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 11.5.42), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-749: Exposed Dangerous Method or Function, where the product provides an applications programming interface (api) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted. In Typo3/cms scheduler, 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

### Problem A vulnerability has been identified in the backend user interface functionality involving deep links. Specifically, this functionality is susceptible to Cross-Site Request Forgery (CSRF). Additionally, state-changing actions in downstream components incorrectly accepted submissions via HTTP GET and did not enforce the appropriate HTTP method. Successful exploitation of this vulnerability requires the victim to have an active session on the backend user interface and to be deceived into interacting with a malicious URL targeting the backend, which can occur under the following conditions: * the user opens a malicious link, such as one sent via email. * the user visits a compromised or manipulated website while the following settings are misconfigured: + `security.backend.enforceReferrer` feature is disabled, + `BE/cookieSameSite` configuration is set to `lax` or `none` The vulnerability in the affected downstream component “Scheduler Module” allows attackers to trigger pre-defined command classes - which can lead to unauthorized import or export of data in the worst case. ### Solution Update to TYPO3 versions 11.5.42 ELTS that fixes the problem described. ### Credits Thanks to Gabriel Dimitrov who reported this issue and to TYPO3 core and security members Benjamin Franzke, Oliver Hader, Andreas Kienast, Torben Hansen, Elias Häußler who fixed the issue.
