CVE-2020-13481
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 · uneditedCertain Lexmark products through 2020-05-25 allow XSS which allows an attacker to obtain session credentials and other sensitive information.
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 confidenceThis is a cross-site scripting (XSS) vulnerability in certain Lexmark products that allows remote attackers to inject malicious scripts into web pages served by the device. Successful exploitation enables attackers to steal session credentials and other sensitive information from users interacting with the affected Lexmark web interface.

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 Lexmark device modelLocate the product label on the physical device or check the web interface login page for the model number (often displayed in the corner or footer of the login screen)Affected if The device is a Lexmark product with a web management interface
-
Determine the installed firmware versionAccess the web interface, navigate to the Settings or Status section, and locate the firmware version field. Alternatively, check the support/diagnostics page or print a configuration page from the device control panelAffected if The firmware version cannot be verified or is unknown
-
Verify the web interface is enabledAttempt to access the device IP address over HTTP/HTTPS in a web browser. Confirm the Lexmark login page loads successfullyAffected if The web interface is accessible and responds with a Lexmark login page
-
Check network exposure of the web interfaceReview firewall rules or network configuration to determine if the device web interface is reachable from untrusted networks (such as the internet or guest networks)Affected if The web interface is exposed to networks outside the trusted local network
-
Review device logs for suspicious requestsAccess the device system logs or event log through the web interface (typically under Diagnostics or Logs) and search for unusual URL patterns, unexpected parameters, or known XSS payload signaturesAffected if Logs contain evidence of malicious requests containing script tags or unusual characters in URL parameters
The environment is affected if the Lexmark device has its web interface enabled and the installed firmware version falls within the vulnerable version range for CVE-2020-13481, which requires verifying the specific model and firmware version against vendor documentation.

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 or security patch for affected Lexmark products. Until patched, users should avoid clicking untrusted links to the Lexmark device interface and administrators should use browser XSS filters.
