CVE-2019-1822
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 vulnerability in the web-based management interface of Cisco Prime Infrastructure (PI) and Cisco Evolved Programmable Network (EPN) Manager could allow an authenticated, remote attacker to execute code with root-level privileges on the underlying operating system. This vulnerability exist because the software improperly validates user-supplied input. An attacker could exploit this vulnerability by uploading a malicious file to the administrative web interface. A successful exploit could allow the attacker to execute code with root-level privileges on the underlying operating system.
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 · high confidenceThis is an authenticated remote code execution vulnerability in Cisco Prime Infrastructure and EPN Manager's web-based management interface. The vulnerability stems from improper validation of user-supplied input during file upload, allowing an authenticated attacker to upload a malicious file and execute arbitrary code with root-level privileges on the underlying operating system.

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 installed Cisco productAccess the web management interface and check the version information, typically found in Help > About or the login page footer. Alternatively, check the system using CLI: 'show version' or look for installation directories like /opt/CSCOlumos or /opt/primeinfraAffected if The product is Cisco Evolved Programmable Network Manager or Cisco Prime Infrastructure
-
Determine exact version numberIn the web interface, navigate to Administration > Settings > Software Updates or Help > About to view the precise version build. In CLI, run 'show version' or check /opt/CSCOlumos/version.txt for EPN ManagerAffected if Version is below 3.0.1 for EPN Manager or below 3.4.1 for Prime Infrastructure
-
Verify web management interface is accessibleConfirm the web-based management interface (HTTPS on port 443 or 8080) is reachable from network. Check if the interface is exposed to untrusted networksAffected if The web interface is accessible to unauthenticated or untrusted network segments
-
Review authentication controlsCheck that strong authentication is required for web interface access. Verify user accounts and privilege levels in Administration > User Management or equivalentAffected if The interface permits authentication with low-privilege accounts or uses default credentials
-
Inspect for unauthorized file uploadsCheck server filesystem for unexpected files in web-accessible directories such as /tftpboot, /tmp, or upload staging directories. Review web server logs for suspicious POST requests to file upload endpointsAffected if Unexpected files exist or unusual upload activity is logged in web server access logs
Your environment is affected if you run EPN Manager below 3.0.1 or Prime Infrastructure below 3.4.1 and the web management interface is accessible to authenticated attackers.

From vendor data3.0.13.4.1
Apply the vendor-supplied patches for CVE-2019-1822. Until patches are available, restrict administrative web interface access to trusted users only and monitor for suspicious file upload activities.
