Detailsinfo

A vulnerability classified as critical has been found in BeWelcome Rox (the affected version is unknown). Affected is the function RoxPOSTHandler::getCallbackAction. The manipulation of the argument formkit_memory_recovery with an unknown input leads to a deserialization vulnerability. CWE is classifying the issue as CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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).

The weakness was presented by Drew Webber. The advisory is available at github.com. This vulnerability is traded as CVE-2025-34292 since 04/15/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit.
