Technical details

SysAid On-Prem versions up to and including 23.3.40 are vulnerable to an unauthenticated XML External Entity (XXE) vulnerability (CWE-611). The flaw exists within the 'Checkin' processing functionality, where the application fails to properly restrict or validate XML external entity references in incoming requests. A remote, unauthenticated attacker can exploit this by sending a specially crafted XML payload to the server. Successful exploitation allows the attacker to read arbitrary files from the local file system and perform actions leading to the takeover of administrator accounts. This vulnerability is confirmed to be exploited in the wild and is addressed in version 24.4.60.
