CVE-2023-50737
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 · uneditedThe SE menu contains information used by Lexmark to diagnose device errors. A vulnerability in one of the SE menu routines can be leveraged by an attacker to execute arbitrary code.
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 vulnerability exists in the Service Engineering (SE) menu routine of Lexmark devices that allows an attacker to execute arbitrary code. The SE menu contains diagnostic information intended for troubleshooting device errors, but a flaw in one of its routines can be exploited to achieve code execution.

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.
-
Confirm Lexmark device in environmentIdentify the printer or multifunction device through its web interface, console output, or physical label. Note the exact model number.Affected if Device is not a Lexmark product (not applicable)
-
Check installed firmware versionAccess the device web interface (Settings > General > About) or print a configuration/ Menu Settings page to obtain the current firmware version. Compare this against the version listed in Lexmark's security advisory for CVE-2023-50737.Affected if Firmware version is earlier than the patched version released by Lexmark for this CVE
-
Verify SE menu accessibilityAccess the Service Engineering (SE) menu through the device control panel (often via a specific key combination during boot) or check the web interface for SE menu or diagnostic function access. Note whether the menu is enabled or accessible without additional authentication.Affected if SE menu is accessible on the device (vulnerability requires SE menu to be present and accessible)
-
Review network exposure of management interfacesCheck firewall rules, network scans, or VLAN configurations to determine if the device web UI or other management ports are exposed to untrusted networks.Affected if Device management interfaces are reachable from untrusted network segments (exploitation is easier with network access)
A Lexmark device is likely affected if it runs firmware older than the patched version AND has the SE menu accessible (particularly if network-accessible), as the vulnerability resides in the SE menu routine.
Generated from the published advisory. Verify against your own configuration.
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 dataApply the vendor-supplied firmware update from Lexmark to patch the vulnerable SE menu routine. If immediate patching is not possible, restrict network access to the device management interfaces and disable the SE menu if feasible.
