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
Cisco Unified Wireless Network (UWN) Solution 7.x before 7.0.98.0 does not properly implement TLS and SSL, which has unspecified impact and remote attack vectors, aka Bug ID CSCtd01611.

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

Cisco Unified Wireless Network (UWN) Solution versions 7.x prior to 7.0.98.0 contain improper TLS/SSL implementation vulnerabilities allowing remote attackers to exploit unspecified attack vectors, resulting in critical-impact compromises (CVSS 10).

MitigationUpgrade Cisco UWN Solution to version 7.0.98.0 or later to address the TLS/SSL implementation deficiencies; if upgrade is not feasible, isolate affected systems and monitor for indicators of compromise.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 UWN Solution installation
    Locate Cisco Wireless LAN Controllers (WLC) or lightweight access points (LAPs) in your environment. These are the core components of the Cisco Unified Wireless Network Solution. Check network documentation or physically inspect data center racks for Cisco WLC devices model numbers such as 5500, 4400, or 2500 series controllers.
    Affected if N/A - this step identifies if the product is present
  2. Check UWN Solution software version
    On the Cisco Wireless LAN Controller, access the CLI and run the 'show version' command, or access the web interface and navigate to Monitor > Controller > Software Version. Record the exact software version number displayed.
    Affected if N/A - this step identifies the installed version for comparison
  3. Compare version against affected range
    Compare the installed version to the affected range: versions 7.0 and any 7.x version prior to 7.0.98.0. Note that version 7.0.98.0 itself is NOT affected.
    Affected if If the installed version is 7.0.x where x is less than 98, or exactly version 7.0, the system is vulnerable to the TLS/SSL implementation flaws
  4. Verify TLS/SSL services are in use
    Check if the Wireless LAN Controller has web-based management (HTTP/HTTPS), telnet, or SSH enabled. Run 'show service内部的' in the WLC CLI to see enabled management interfaces. The vulnerability affects TLS/SSL implementation, so these services must be accessible for exploitation.
    Affected if If HTTPS or other TLS/SSL protected management interfaces are enabled and the version is in the affected range, the TLS/SSL flaws can be exploited

A system is affected if it runs Cisco Unified Wireless Network Solution Software version 7.0 or any 7.x version prior to 7.0.98.0, with TLS/SSL management services exposed.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Cisco UWN Solution to version 7.0.98.0 or later to address the TLS/SSL implementation deficiencies; if upgrade is not feasible, isolate affected systems and monitor for indicators of compromise.

Recommended fix Moderate confidence

Cisco UWN Solution 7.0.98.0 or later

  1. 1. Identify the current Cisco UWN Solution software version via the Wireless Control System (WCS) or Wireless LAN Controller (WLC) CLI
  2. 2. Access the Cisco Software Download center at software.cisco.com
  3. 3. Download Cisco UWN Solution version 7.0.98.0 or later
  4. 4. Backup the current WCS/WLC configuration
  5. 5. Upgrade the Wireless LAN Controller to the fixed version via the CLI or web interface
  6. 6. Verify the TLS/SSL configuration after upgrade to ensure proper implementation
  7. 7. Confirm the upgrade was successful and test wireless network functionality
Caveat Review Cisco release notes for 7.0.98.0 to check for configuration changes, potential controller reboot requirements, and compatibility with existing APs
