CVE-2024-55924
Published: 14 January 2025
Description
TYPO3 is a free and open source Content Management Framework. 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: 1. `security.backend.enforceReferrer` feature is disabled, 2. `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. Users are advised to update to TYPO3 versions 11.5.42 ELTS which fixes the problem described. There are no known workarounds for this vulnerability.
Security Summary
CVE-2024-55924 is a Cross-Site Request Forgery (CSRF) vulnerability in the backend user interface deep links of TYPO3, a free and open source Content Management Framework. Additionally, state-changing actions in downstream components, such as the Scheduler Module, incorrectly accept submissions via HTTP GET requests without enforcing the proper HTTP method. This issue is classified under CWE-352 (CSRF) and CWE-749 (Exposed Dangerous Method or Function), with a CVSS v3.1 base score of 8.0 (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H).
Exploitation requires the victim to have an active session in the TYPO3 backend user interface and to be deceived into interacting with a malicious URL. This can occur if the user opens a malicious link, such as one sent via email, or visits a compromised or manipulated website while specific settings are misconfigured: the security.backend.enforceReferrer feature is disabled, and the BE/cookieSameSite configuration is set to lax or none. A successful attack allows triggering of pre-defined command classes in the Scheduler Module, potentially leading to unauthorized import or export of data.
The TYPO3 security advisories recommend updating to version 11.5.42 ELTS, which addresses the vulnerability. There are no known workarounds available.
