CVE-2018-15450
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 UI of Cisco Prime Collaboration Assurance could allow an authenticated, remote attacker to overwrite files on the file system. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by using a specific UI input field to provide a custom path location. A successful exploit could allow the attacker to overwrite files on the file 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 · moderate confidenceThis is a path traversal vulnerability in Cisco Prime Collaboration Assurance's web UI that allows authenticated attackers to overwrite arbitrary files on the filesystem by providing custom path locations through insufficiently validated input fields. The attacker needs valid authentication credentials to exploit this flaw.

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.
-
Confirm Cisco Prime Collaboration installationLocate the installation directory (typically under /opt/cisco/prime or C:\Program Files\Cisco\Prime on Windows) or check running processes for 'prime' or 'collaboration' servicesAffected if Cisco Prime Collaboration software is installed on the system
-
Verify the installed versionCheck the version by reviewing installation logs, the about page in the web UI, or running 'show version' command if CLI access is availableAffected if The installed version is exactly 12.1
-
Determine if the web UI is exposedCheck if ports 443, 8443, or 8080 are listening and accessible (for example, using netstat or nmap to scan local ports or remote endpoints)Affected if The web interface is accessible over the network
-
Confirm authentication is enabledVerify that user accounts exist for the web UI by checking the local user database or authentication configuration files in the installation directoryAffected if Valid user credentials can be obtained or created for the web interface
-
Identify file operation accessLog into the web UI and navigate to any features that involve file upload, export, or write operations (such as backup/restore, report generation, or configuration import)Affected if Authenticated users have access to file-related operations in the web UI
User is affected if Cisco Prime Collaboration version 12.1 is running with its web UI accessible and authenticated users can access file operation features.

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 patch from Cisco, implement strict input validation and path sanitization on all file-related UI fields, and enforce least-privilege access controls to limit which authenticated users can access file operations.
