CVE-2023-50733
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 · uneditedA Server-Side Request Forgery (SSRF) vulnerability has been identified in the Web Services feature of newer Lexmark devices.
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 Server-Side Request Forgery (SSRF) vulnerability exists in the Web Services feature of Lexmark network devices. This allows an attacker to induce the device to make arbitrary HTTP requests to internal or external resources, potentially bypassing network boundaries and accessing sensitive internal services.

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 as a Lexmark network deviceAccess the device management interface or check the device label/metadata to confirm the manufacturer is Lexmark and it is a network-capable device such as a printer or multifunction productAffected if The device is a Lexmark network device
-
Confirm Web Services feature is enabledLog into the device web interface or embedded web server and navigate to the Network/Ports or Web Services settings section. Verify if the Web Services feature is turned onAffected if Web Services is enabled on the device (the SSRF vulnerability exists only when this feature is active)
-
Determine the installed firmware versionAccess the device status or settings page in the web interface, or print a configuration/_settings page from the device control panel. Locate the firmware or firmware revision fieldAffected if The installed firmware version matches or falls within the affected version range for this CVE (compare your version to Lexmark's published affected versions)
-
Review network logs for suspicious outbound HTTP requestsCheck the device system logs, network logs, or audit logs for outbound HTTP requests originating from the device to unexpected internal or external IP addresses, especially requests to internal network resources that would not normally be accessed by the deviceAffected if Unexpected or unauthorized outbound HTTP requests appear in the logs, indicating potential exploitation attempts or successful SSRF activity
You are affected if you have a Lexmark network device with Web Services enabled and the firmware version is within the affected range, or if you observe unexplained outbound HTTP requests from the device.
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 vendor-provided firmware updates for affected Lexmark devices; if unavailable, restrict network access to the Web Services interface and monitor for suspicious outbound requests.
