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 administrative web interface in Cisco Hosted Collaboration Solution (HCS) 10.6(1) and earlier allows remote authenticated users to execute arbitrary commands via crafted input to unspecified fields, aka Bug ID CSCut02786.

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 confidence

Command injection vulnerability in Cisco Hosted Collaboration Solution administrative web interface where authenticated users can execute arbitrary OS commands through crafted input to unspecified fields. This is a classic input validation failure allowing shell command injection.

MitigationApply Cisco patch for CSCut02786. Until patched, restrict administrative web interface access to trusted IP addresses/networks only, enforce strong authentication, and monitor for anomalous administrative sessions.

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 Cisco HCS installation
    Locate Cisco HCS components on the system or check the installed package version using the system package manager or Cisco-specific version lookup commands.
    Affected if The system is running any Cisco Hosted Collaboration Solution installation.
  2. Check the exact HCS version
    Run the Cisco command to display the HCS version (for example, 'show version' or 'utils system version' from the Cisco CLI), or inspect the version file in the HCS installation directory.
    Affected if The installed version matches any of the following: 8.0(2)_base, 8.6(1)_base, 8.6(2)_base, 9.0(1)_base, 9.1(1)_base, 9.2(1)_base, 9.5(1)_base, 10.0(1)_base, 10.1(1)_base, 10.1(2)_base, 10.5(1)_base, or 10.6(2)_base.
  3. Confirm administrative web interface is enabled
    Check if the Cisco HCS administrative web interface service is running and accessible, typically on port 8443 or 443, by inspecting the running services or checking the web interface URL.
    Affected if The administrative web interface is exposed and operational on the system.
  4. Verify administrative access is not restricted to trusted sources
    Inspect the access control lists or firewall rules that govern access to the HCS administrative web interface port to determine if source IP restrictions are applied.
    Affected if The administrative web interface is accessible from untrusted networks or IP addresses without IP-based restrictions.

A user is affected if the system runs Cisco HCS version 8.0(2), 8.6(1), 8.6(2), 9.0(1), 9.1(1), 9.2(1), 9.5(1), 10.0(1), 10.1(1), 10.1(2), 10.5(1), or 10.6(2) and the administrative web interface is accessible.
