CVE-2025-34292: CWE-502 Deserialization of Untrusted Data in BeWelcome Rox
Rox, the software running BeWelcome, contains a PHP object injection vulnerability resulting from deserialization of untrusted data. User-controlled input is passed to PHP's unserialize(): the POST parameter `formkit_memory_recovery` in \\RoxPostHandler::getCallbackAction and the 'memory cookie' read by \\RoxModelBase::getMemoryCookie (bwRemember). (1) If present, `formkit_memory_recovery` is processed and passed to unserialize(), and (2) restore-from-memory functionality calls unserialize() on the bwRemember cookie value. Gadget chains present in Rox and bundled libraries enable exploitation of object injection to write arbitrary files or achieve remote code execution. Successful exploitation can lead to full site compromise. This vulnerability was remediated with commit c60bf04 (2025-06-16).
AI Analysis
Technical Summary
CVE-2025-34292 is a PHP object injection vulnerability in Rox, the software running BeWelcome, caused by deserialization of untrusted data. Specifically, the POST parameter 'formkit_memory_recovery' and the 'memory cookie' (bwRemember) are passed to PHP's unserialize() function without sufficient validation. This allows attackers to leverage gadget chains in Rox and its bundled libraries to perform object injection attacks, enabling arbitrary file writes or remote code execution. The vulnerability was remediated by a code commit on 2025-06-16.
Potential Impact
Successful exploitation of this vulnerability can lead to remote code execution and arbitrary file writes, resulting in full compromise of the affected BeWelcome Rox installation. The critical CVSS score of 9.4 reflects the high impact on confidentiality, integrity, and availability of the system.
Mitigation Recommendations
A fix for this vulnerability was implemented in a commit dated 2025-06-16. Users should update Rox to the fixed version to remediate this issue. Since the product is not a cloud service, remediation requires applying the official patch or updated software version containing the fix. Patch status is not explicitly stated beyond the commit date; users should verify the vendor's repository or advisory for the exact fixed version and apply updates accordingly.
