Exploited! SysAid On-Prem XML External Entity Vulnerability (CVE-2025-2775)
SysAid has patched a critical XML External Entity (XXE) flaw that lets unauthenticated attackers turn a routine /mdm check-in request into full administrator compromise—and, when chained with a newly disclosed command-injection bug, into remote code execution (RCE). The vulnerability, tracked as CVE-2025-2775, affects all SysAid On-Prem deployments up to 23.3.40 and is now fixed in 24.4.60.
