## Technical details

An unauthenticated XML External Entity (XXE) vulnerability exists in SysAid On-Prem versions up to and including 23.3.40. The flaw is located within the Server URL processing functionality, where the application fails to properly restrict or sanitize XML external entity references (CWE-611). A remote, unauthenticated attacker can exploit this by sending a specially crafted XML payload to the vulnerable endpoint. Successful exploitation allows the attacker to read arbitrary files from the server's file system or perform an administrator account takeover. This vulnerability has been observed in active exploitation, and users are advised to upgrade to a patched version (e.g., 24.40.60) as per vendor release notes.
