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
Multiple cross-site request forgery (CSRF) vulnerabilities in Cisco Unified Communications Manager (Unified CM) allow remote attackers to hijack the authentication of arbitrary users for requests that perform arbitrary Unified CM operations, aka Bug ID CSCui13033.

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

Multiple cross-site request forgery (CSRF) vulnerabilities exist in Cisco Unified Communications Manager (Unified CM) web interface. Attackers can craft malicious requests that trick authenticated administrators into performing unintended Unified CM operations, such as configuration changes, user management actions, or other administrative functions. Since the attack exploits the trust a web application places in authenticated user sessions, no authentication bypass is required—the attacker only needs to induce a logged-in user to trigger the malicious request.

MitigationApply the Cisco patch for Bug ID CSCui13033 when released; in the interim, restrict administrative web interface access to trusted networks only and use browser-based CSRF protections where feasible. Organizations should also educate administrators about avoiding clicking untrusted links while logged into Unified CM.

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. Confirm Cisco Unified Communications Manager is installed
    Identify if Unified CM is deployed in your environment by checking for the application on the system or reviewing installed software inventory
    Affected if Unified CM is present and running in the environment
  2. Determine if the web interface is accessible
    Check if the Unified CM administrative web interface port is open and reachable (typically TCP 8443 or 443 for HTTPS). Use a network scan or check firewall rules.
    Affected if The web interface port is open and accepting connections from your test system
  3. Verify web interface exposure
    Review firewall rules and network segmentation to determine if the administrative web interface is accessible from untrusted networks or the internet
    Affected if The web interface is reachable from networks outside your trusted administrative zone
  4. Check for CSRF protection mechanisms
    Inspect the web application forms and HTTP responses for CSRF tokens or anti-CSRF measures. Check if the application validates the Referer header or Origin header on POST requests.
    Affected if The web forms lack CSRF tokens and the application does not validate request origins
  5. Verify SameSite cookie attributes
    Examine HTTP responses from the web interface to see if session cookies have the SameSite attribute set to Strict or Lax
    Affected if Session cookies are missing SameSite attributes and are sent on cross-site requests

Your environment is affected if Cisco Unified Communications Manager is installed and its administrative web interface is accessible, since all versions of this product contain the CSRF vulnerability.
