CVE-2022-45719
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 · uneditedIP-COM M50 V15.11.0.33(10768) was discovered to contain a buffer overflow via the gotoUrl parameter in the formPortalAuth function.
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 · moderate confidenceA buffer overflow vulnerability exists in the IP-COM M50 router firmware version 15.11.0.33(10768) in the formPortalAuth function. The gotoUrl parameter does not properly validate input length before copying to a fixed-size buffer, allowing an attacker to overwrite adjacent memory with crafted input. The critical CVSS score of 9.8 suggests this is exploitable remotely without authentication.

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 the device modelAccess the router admin panel or check the device label to confirm the model is IP-COM M50Affected if Device is not an IP-COM M50 router (not affected)
-
Check the firmware versionLog into the router admin interface and navigate to System Settings > Firmware Upgrade, or use the command line and check /etc/osrelease or a version file in the firmware. Compare the installed version to 15.11.0.33(10768)Affected if Firmware version is exactly 15.11.0.33(10768)
-
Verify management interface accessibilityDetermine if the router web management interface (HTTP/HTTPS on ports 80/443 or custom ports) is accessible from the network. Check router firewall rules and WAN/LAN configurationAffected if Management interface is exposed to untrusted networks (increases exposure risk)
-
Confirm formPortalAuth function existenceInspect the firmware binary (if accessible via firmware extraction) or check HTTP requests for the formPortalAuth endpoint. This function handles portal authentication and contains the vulnerable gotoUrl parameterAffected if The formPortalAuth function is present and accepts the gotoUrl parameter without length validation
The environment is affected if the device is an IP-COM M50 router running firmware version exactly 15.11.0.33(10768) and the management interface is accessible, allowing unauthenticated attackers to send crafted gotoUrl parameters to trigger the buffer overflow.

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 dataUpdate to a patched firmware version if available, or implement network segmentation to restrict access to the affected management interface. Input validation should be added to the gotoUrl parameter in formPortalAuth to enforce reasonable length limits.
