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
The default installation of Cisco voice products, when running the IBM Director Agent on IBM servers before OS 2000.2.6, does not require authentication, which allows remote attackers to gain administrator privileges by connecting to TCP port 14247.

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
How this class of weakness works · CWE-287

The mechanism that verifies who a user is can be side-stepped or fooled, letting an attacker act as someone they're not. Everything built on top of that identity then becomes untrustworthy. Fixing it means hardening the full authentication flow, including edge cases, tokens, and secondary paths.

Recommended fix High confidence

IBM OS 2000.2.6 or later (which includes the fixed IBM Director Agent)

  1. Identify all IBM servers running the IBM Director Agent that host the affected Cisco voice products
  2. Verify the IBM OS version running on these servers (pre-2000.2.6 is vulnerable)
  3. Upgrade the IBM server operating system to version 2000.2.6 or later, which includes the fixed IBM Director Agent with authentication enabled
  4. Alternatively, if upgrading the OS is not feasible, disable the IBM Director Agent service on affected servers
  5. If the IBM Director Agent must remain enabled, configure authentication for the IBM Director Agent according to IBM's documentation for your specific version
  6. After applying the fix, verify that TCP port 14247 now requires authentication or is otherwise secured
  7. Test that the affected Cisco voice products continue to function properly after the change
Caveat Upgrading IBM OS to version 2000.2.6 may require downtime and could affect compatibility with legacy Cisco voice product versions. Verify application compatibility before upgrading.
