{"cve":"CVE-2025-34292","nvd":{"published":"2025-10-27T15:15:38.317","modified":"2026-10-08T11:10:00.250","status":"Deferred","description":"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).","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4},"cvss_v3":null,"cwes":["CWE-502"],"references":["https://gist.github.com/mcdruid/c0f7c42b28949c7d86cf77d0c674f398","https://github.com/BeWelcome/rox","https://github.com/BeWelcome/rox/commit/c60bf04","https://www.vulncheck.com/advisories/rox-php-object-injection-rce","https://gist.github.com/mcdruid/c0f7c42b28949c7d86cf77d0c674f398"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:12:35.277909958+00:00"},"epss":{"cve":"CVE-2025-34292","score":0.00778,"percentile":0.55575,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
