Questions about CVE-2025-2775
What does this mean?
The check-in processing component parses XML sent to the /mdm/checkin endpoint and is vulnerable to XML External Entity injection. Researchers chained this into pre-authenticated remote command execution as SYSTEM.Source: labs.watchtowr.com
Am I affected, and how do I check?
SysAid On-Prem versions up to and including 23.3.40 are listed as affected, and the researchers tested version 23.3.40. To check a installation, compare its installed SysAid On-Prem version with 23.3.40.Source: labs.watchtowr.com
What should I do about it?
The checked facts do not name a fixed version, so no upgrade target can be confirmed from them.Source: labs.watchtowr.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2025-07-22, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
What if there's no patch?
The checked facts list no fix and no workaround, so neither can be confirmed. The known attack path is an HTTP POST to /mdm/checkin.Source: labs.watchtowr.com
