CVE-2023-20129
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 · uneditedMultiple vulnerabilities in the web-based management interface of Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager (EPNM) could allow a remote attacker to obtain privileged information and conduct cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks. For more information about these vulnerabilities, see the Details section of this advisory.

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 if Cisco Prime Infrastructure is deployedLog into the device and run 'show version' or access the web UI login page to confirm the product nameAffected if The product is Cisco Prime Infrastructure
-
Check Cisco Prime Infrastructure versionFrom the web UI, go to Home > Dashboard or use 'show version' CLI command to retrieve the installed version numberAffected if The version is <= 3.7, 3.8, 3.8.1, 3.9, 3.9.1, or >= 3.10 but < 3.10.2
-
Identify if Cisco Evolved Programmable Network Manager is deployedLog into the device and run 'show version' or access the web UI login page to confirm the product name is Cisco EPNMAffected if The product is Cisco EPNM
-
Check Cisco EPNM versionFrom the web UI, go to Administration > System > Software Version or use 'show version' CLI command to retrieve the installed version numberAffected if The version is < 5.0.2.5, >= 5.1 but < 5.1.4.2, >= 6.0 but < 6.0.2.1, or >= 6.1 but < 6.1.1.1
-
Verify web management interface is accessibleConfirm the web-based management interface (HTTP/HTTPS on port 443 or 8080) is listening and reachable on the deviceAffected if The web management interface is exposed and the version is in the affected range
You are affected if either Cisco Prime Infrastructure or Cisco EPNM is running and the installed version matches the affected version ranges, with the web management interface enabled.
