CVE-2025-2775
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSysAid On-Prem versions <= 23.3.40 are vulnerable to an unauthenticated XML External Entity (XXE) vulnerability in the Checkin processing functionality, allowing for administrator account takeover and file read primitives.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSysAid On-Prem versions 23.3.40 and earlier contain an unauthenticated XML External Entity (XXE) vulnerability in the Checkin processing functionality. Attackers can exploit this to read arbitrary files from the server's filesystem and potentially compromise administrator accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SysAid On-Prem versionAccess the SysAid web interface and navigate to the Admin section, About page, or check the footer/banner for the version number. Alternatively, check installation files or configuration for version metadata.Affected if Installed version is 23.3.40 or lower
-
Confirm Checkin functionality is enabledLog into SysAid admin panel and locate the Checkin processing feature in the system settings, workflows, or integrations configuration. Verify whether this feature is currently active or exposed.Affected if Checkin functionality is enabled and accessible to users or unauthenticated attackers
-
Verify Checkin endpoint accessibilityAttempt to access the Checkin endpoint URL (typically under paths like /checkin, /api/checkin, or similar) from the network to determine if it responds without authentication.Affected if The Checkin endpoint is reachable without authentication and responds to requests
-
Assess network exposure of the Checkin serviceDetermine whether the SysAid web application and its Checkin endpoint are exposed to untrusted networks, the internet, or external IP addresses versus only being accessible from trusted internal networks.Affected if The SysAid server and Checkin endpoint are reachable from untrusted networks or the internet
You are affected if your SysAid On-Prem version is 23.3.40 or lower, the Checkin functionality is enabled, and the Checkin endpoint is accessible to unauthenticated attackers on your network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a patched SysAid version > 23.3.40, or if no patch is available, disable or sanitize XML processing in the Checkin functionality and apply input validation to reject external entity declarations.
