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 · unedited
A vulnerability in the web-based management interface of Cisco Unified Communications Manager IM & Presence Service (formerly CUPS) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on a targeted device via a web browser and with the privileges of the user. Cisco Bug IDs: CSCvi55878.

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 confidence

A CSRF (Cross-Site Request Forgery) vulnerability in the web-based management interface of Cisco Unified Communications Manager IM & Presence Service allows unauthenticated remote attackers to trick authenticated administrators into performing unintended actions by luring them to click malicious links. The root cause is missing or insufficient CSRF token validation in the web interface.

MitigationApply the Cisco vendor patch for CSCvi55878 when released. In the interim, educate administrators about avoiding untrusted links and consider network segmentation to limit exposure of the management 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Cisco Unified Communications Manager IM & Presence Service is installed
    Locate the product on your system or check your inventory of deployed Cisco collaboration software. This is a separate component from standard Cisco Unified Communications Manager.
    Affected if The product is not installed on your environment.
  2. Check the installed version of the IM & Presence Service
    Access the product via its admin web interface or use the CLI command 'utils system version' or 'show version' depending on your access method, then compare the displayed version to 11.5(1).
    Affected if The installed version is exactly 11.5(1).
  3. Verify the web-based management interface is accessible
    Attempt to reach the admin web interface via HTTPS on the standard ports (typically 8443 or 443) for the IM & Presence Service. If the interface is unreachable from your network perspective, the CSRF attack surface is reduced.
    Affected if The web management interface is exposed and accessible to users who could be targeted with malicious links.
  4. Confirm administrator accounts exist and can access the web interface
    Log into the web-based management interface with an administrator account. CSRF attacks require authenticated administrators to be tricked into clicking malicious links.
    Affected if There are active administrator accounts with access to the web management interface.

You are affected if you have Cisco Unified Communications Manager IM & Presence Service version 11.5(1) running with its web-based management interface accessible to users who could be targeted.
