Low risk41th percentile - higher than 41% of all known CVEs
Summary
The Rox software running BeWelcome contains a PHP object injection vulnerability due to deserialization of untrusted data. The `formkit_memory_recovery` parameter and the `bwRemember` cookie are passed to unserialize(), allowing an attacker to execute arbitrary code or write files on the server.
Risk Assessment
Successful exploitation can lead to full server compromise, resulting in loss of confidentiality, integrity, and availability of organizational data.
Recommendation
Immediately update Rox software to the version containing commit c60bf04 (2025-06-16) and avoid deserializing user-supplied data without proper validation.
Original NVD description (English source)
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).
