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
A vulnerability in the web-based management interface of Cisco BroadWorks Application Delivery Platform, Cisco BroadWorks Application Server, and Cisco BroadWorks Xtended Services Platform could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of an affected device. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

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

This is a reflected Cross-Site Scripting (XSS) vulnerability in Cisco BroadWorks web-based management interfaces. The flaw exists due to improper validation of user-supplied input in the web interface, allowing an unauthenticated attacker to inject malicious scripts via a crafted link. Successful exploitation enables arbitrary script execution in the user's browser context or access to sensitive browser-based information.

MitigationApply the relevant Cisco security patch for this vulnerability. In the interim, educate users about not clicking untrusted links. Implement output encoding and input validation on the affected web interfaces.

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 BroadWorks installation
    Locate Cisco BroadWorks components in your environment: Application Delivery Platform, Application Server, or Xtended Services Platform. Check for processes named 'BroadWorks' or review installed software packages.
    Affected if Any of these three BroadWorks components are present in the environment
  2. Determine the installed version
    Access the web management interface and navigate to the About or System Information page, or run 'rpm -q' or 'dpkg -l' commands for BroadWorks packages if you have CLI access.
    Affected if The version number is lower than: commpilot-24_2022.11 (Application Delivery Platform), ap.as.24.0.944.ap384344 (Application Server), or ap.xsp.23.0.1075.ap384344 (Xtended Services Platform)
  3. Verify web interface accessibility
    Attempt to access the BroadWorks web management interface via HTTP/HTTPS from a browser or curl command to confirm the service is running.
    Affected if The web interface is accessible and responding on ports 80, 443, or configured web service ports

Your environment is affected if any Cisco BroadWorks component (Application Delivery Platform, Application Server, or Xtended Services Platform) is running with a version lower than the specified thresholds and the web management interface is accessible to users or attackers.

Mitigation

Apply the relevant Cisco security patch for this vulnerability. In the interim, educate users about not clicking untrusted links. Implement output encoding and input validation on the affected web interfaces.

Recommended fix Moderate confidence

commpilot-24_2022.11 (Application Delivery Platform), ap.as.24.0.944.ap384344 (Application Server), or ap.xsp.23.0.1075.ap384344 (Xtended Services Platform)

  1. 1. Identify which Cisco BroadWorks product(s) are deployed: Application Delivery Platform, Application Server, or Xtended Services Platform
  2. 2. Check the current version of the installed BroadWorks component(s) through the web-based management interface or system administration tools
  3. 3. For BroadWorks Application Delivery Platform: upgrade to version commpilot-24_2022.11 or later
  4. 4. For BroadWorks Application Server: upgrade to version ap.as.24.0.944.ap384344 or later
  5. 5. For BroadWorks Xtended Services Platform: upgrade to version ap.xsp.23.0.1075.ap384344 or later
  6. 6. After upgrade, clear browser cache and verify the web-based management interface is functioning correctly
  7. 7. Test that the XSS vulnerability is no longer exploitable by attempting the documented attack vector
Caveat Standard upgrade risks apply - review Cisco release notes for any configuration or compatibility changes before deploying
