Technical details

An unrestricted file upload vulnerability (CWE-434) exists in OpenSTAManager versions 2.10 and earlier. The flaw is located in the 'modules/aggiornamenti/upload_modules.php' component, which handles module updates. A remote attacker with high privileges (administrative access) can exploit this by uploading a malicious PHP script or other dangerous file types. Successful exploitation allows for arbitrary code execution on the underlying server, potentially leading to full system compromise. While a proof-of-concept was referenced in initial reports, users are advised to restrict access to the update module and upgrade to a patched version if available.
