CVE-2025-2776SysAid On-Prem — entity injection in the server address handler

SysAid On-Prem 23.3.40 and earlier accept markup (XML) on the server address handler without restricting external entities, which an unauthenticated attacker turns into reading files and taking over an administrator account.

YOUR NEXT MOVE

Upgrade SysAid On-Prem past 23.3.40 now; it is the companion of a second entity injection flaw, so confirm the release covers both handlers.
