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
Unspecified vulnerability in Cisco Wireless Control System (WCS) before 4.0.87.0 allows remote authenticated users to gain the privileges of the SuperUsers group, and manage the application and its networks, related to the group membership of user accounts, aka Bug ID CSCsg05190.

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

An unspecified vulnerability in Cisco Wireless Control System (WCS) versions prior to 4.0.87.0 allows remote authenticated users to escalate their privileges to SuperUsers by manipulating group membership settings for user accounts, granting them full administrative control over the application and managed wireless networks.

MitigationUpgrade Cisco WCS to version 4.0.87.0 or later, or apply the vendor patch for Bug ID CSCsg05190 to remediate the privilege escalation vector.

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 WCS is installed
    Identify if Cisco Wireless Control System is deployed in your environment. This is typically a Windows or Linux server running the WCS application. Check for the WCS installation directory or running processes named 'wcs' or similar.
    Affected if Cisco WCS software is present on the system
  2. Determine installed WCS version
    Locate the version number of the installed Cisco WCS. This is commonly visible in the WCS web interface under 'Help' > 'About', or stored in version/configuration files on the server (such as version.properties or similar).
    Affected if Unable to determine the version from the WCS interface or system files
  3. Compare version against fixed release
    Compare your installed WCS version number to the fixed release 4.0.87.0. If your version is a 4.0.x release, check if it is less than 4.0.87.0 (for example, 4.0.85.0, 4.0.80.0, etc.).
    Affected if The installed version is a 4.0.x release prior to 4.0.87.0 (such as 4.0.95, 4.0.90, 4.0.85, etc.)

You are affected if Cisco Wireless Control System is installed and the running version is a 4.0.x release earlier than 4.0.87.0, as versions prior to 4.0.87.0 contain the privilege escalation vulnerability.

dbcve · scoped
Upgrade available Upgrade to a release after 4.0.95
Interim mitigation

Upgrade Cisco WCS to version 4.0.87.0 or later, or apply the vendor patch for Bug ID CSCsg05190 to remediate the privilege escalation vector.

Recommended fix High confidence

Upgrade to Cisco WCS version 4.0.87.0 or later (current recommended stable release)

  1. 1. Identify the current installed version of Cisco Wireless Control System (WCS) by accessing the WCS console or using the CLI command 'show version'
  2. 2. If the current version is earlier than 4.0.87.0, plan for an upgrade to version 4.0.87.0 or a later stable release
  3. 3. Review Cisco's WCS upgrade documentation for prerequisites, including disk space, backup requirements, and supported upgrade paths
  4. 4. Back up the current WCS configuration and database before initiating the upgrade
  5. 5. Download the WCS software version 4.0.87.0 or later from Cisco's software download center (requires valid Cisco service contract)
  6. 6. Initiate the upgrade via the WCS web interface under Administration > Software Upgrade, or use the CLI upgrade procedure
  7. 7. After upgrade completes, verify the new version number and confirm WCS services are operational
  8. 8. Validate that the SuperUsers group membership functions correctly and that the privilege escalation vulnerability is mitigated
Caveat Upgrading WCS may require downtime; ensure backup and rollback procedures are in place; some legacy browser compatibility may be affected
