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
Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit these vulnerabilities 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 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 · moderate confidence

This is a cross-site scripting (XSS) vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) Software. The vulnerability stems from insufficient validation of user-supplied input, allowing an authenticated remote attacker to inject malicious script code via crafted links. Successful exploitation enables arbitrary script execution in the context of the interface or access to sensitive browser-based information.

MitigationApply the Cisco security patch when available; until then, user awareness training to avoid clicking untrusted links and implementation of Content Security Policy (CSP) headers can help mitigate the risk of XSS exploitation.

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 the installed FMC product
    Access the web management interface and look for the product name in the login page or admin dashboard, or run 'show version' via CLI on the device
    Affected if Product is not Cisco Secure Firewall Management Center (or Cisco Firepower Management Center)
  2. Determine the FMC software version
    In the web interface, go to System > About > Cisco Firepower Management Center (or Help > About). Via CLI, run 'show version' and look for the release number
    Affected if Version cannot be determined or is not visible in the expected location
  3. Compare installed version against affected ranges
    Check if the installed version falls into any of these ranges: < 6.4.0.15, >= 6.5.0 but < 6.6.5.2, or >= 6.7.0 but < 7.0.2
    Affected if Installed version matches any of the affected version ranges
  4. Verify web-based management interface accessibility
    Confirm that the FMC web interface is accessible on the network (check for open HTTP/HTTPS ports 443/8000 or similar on the management IP)
    Affected if Web interface is exposed and version is in the affected ranges

Your environment is affected if Cisco Secure Firewall Management Center is running and its installed version falls within < 6.4.0.15, >= 6.5.0 to < 6.6.5.2, or >= 6.7.0 to < 7.0.2 with the web management interface enabled.

Interim mitigation

Apply the Cisco security patch when available; until then, user awareness training to avoid clicking untrusted links and implementation of Content Security Policy (CSP) headers can help mitigate the risk of XSS exploitation.

Recommended fix Moderate confidence

Minimum fixed releases: 6.4.0.15 (or upgrade to 6.5.0+), 6.6.5.2 (or upgrade to 6.7.0+), or 7.0.2 (or later 7.x)

  1. For systems on 6.4.x branch: Upgrade to version 6.4.0.15 or later (6.4.0.15, 6.5.0, 6.6.x, or 7.0.x)
  2. For systems on 6.5.0-6.6.5.x branch: Upgrade to version 6.6.5.2 or later (6.6.5.2, 6.7.0, or 7.0.x)
  3. For systems on 6.7.0-7.0.2 branch: Upgrade to version 7.0.2 or later (7.0.2 or later 7.x release)
  4. After upgrade, verify the FMC version matches the fixed release via System > Updates > Product Updates in the web interface
Caveat Review Cisco FMC upgrade guides for compatibility notes; ensure proper backup of configuration before upgrading
