CVE-2019-1819
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 and Cisco Evolved Programmable Network (EPN) Manager software could allow an authenticated, remote attacker to download and view files within the application that should be restricted. This vulnerability is due to improper sanitization of user-supplied input in HTTP request parameters that describe filenames. An attacker could exploit this vulnerability by using directory traversal techniques to submit a path to a desired file location. A successful exploit could allow the attacker to view application files that may contain 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 · high confidenceA directory traversal vulnerability in Cisco Prime Infrastructure and EPN Manager's web-based management interface allows authenticated attackers to view restricted application files by submitting traversal sequences (e.g., ../../) in HTTP request parameters for filenames. The input is not properly sanitized, enabling access to sensitive application files outside the intended web root.

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 productRun 'show version' or check /opt/CSCOlumos/bin/ on the Appliance for Cisco Prime Infrastructure. For EPN Manager, check /opt/epnm/ directory or run 'epnm version' if available. Alternatively, search for 'prime' or 'epnm' in process list via 'ps aux | grep -i prime' or 'ps aux | grep -i epnm'.Affected if The system is running either Cisco Prime Infrastructure or Evolved Programmable Network Manager (EPN Manager).
-
Determine product versionFor Prime Infrastructure, check the web GUI under Administration > Software Updates > Software Type or run 'show version' in the CLI. For EPN Manager, check the web GUI under Settings > EPN Manager Settings > System > Software Version or run 'epnmctl get version' from the command line.Affected if The installed version is below 3.4 for Prime Infrastructure or below 3.0.1 for EPN Manager.
-
Verify web management interface statusCheck if the web-based management interface is enabled and accessible. Review the system configuration for HTTP/HTTPS services on ports 80, 443, 8080, or 8443. Use 'netstat -tlnp | grep -E "(80|443|8080|8443)"' to confirm listening web services.Affected if The web-based management interface is enabled and exposed (even on localhost or internal networks, the flaw can be triggered by an authenticated attacker).
-
Inspect HTTP access logs for traversal patternsReview web server access logs for directory traversal attempts. Logs are typically located in /opt/CSCOlumos/tomcat/logs/ for Prime Infrastructure or /opt/epnm/tomcat/logs/ for EPN Manager. Search for patterns like '../', '..%2F', '%2E%2E/', or multiple consecutive slashes in request URIs.Affected if Malicious traversal sequences are observed in HTTP requests to the web interface.
The environment is affected if Cisco Prime Infrastructure (version below 3.4) or EPN Manager (version below 3.0.1) is installed with the web-based management interface enabled, regardless of network exposure.

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 data3.0.13.4
Apply the vendor patch from Cisco when available. Until patched, restrict access to the web management interface to trusted administrators only and monitor logs for directory traversal patterns in HTTP requests.
