CVE-2022-20646
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 · uneditedMultiple vulnerabilities in the web-based management interface of Cisco Security Manager could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks 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 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 · high confidenceMultiple Cross-Site Scripting (XSS) vulnerabilities in Cisco Security Manager's web-based management interface allow unauthenticated, remote attackers to inject malicious scripts via insufficiently validated user input. Attackers exploit this by tricking users into clicking crafted links, enabling arbitrary script execution in the context of the interface or theft of sensitive browser-based information.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Cisco Security Manager is installedCheck for Cisco Security Manager installation by reviewing installed applications, services, or the presence of its directories. Common installation paths may include C:\Program Files\Cisco\Security Manager or similar. Use 'Get-ItemProperty' or check Add/Remove Programs.Affected if Cisco Security Manager software is present on the system
-
Determine the installed version of Cisco Security ManagerLocate the version information in the Security Manager installation directory, typically in an 'about' or 'version' file, or via the application's Help > About menu if accessible. Common paths include C:\Program Files\Cisco\Security Manager\etc\version or within the application binaries.Affected if The installed version is lower than 4.24 (for example, 4.22, 4.23, or any version shown as less than 4.24)
-
Confirm the web-based management interface is enabledCheck if the Cisco Security Manager web interface service (typically named 'CSM' or 'cman' service) is running and if the web port (default ports often include 443, 8443) is listening. Use 'netstat -an | findstr :443' or similar port scanning commands.Affected if The web management interface is accessible and the service is running
-
Review web server access logs for suspicious URL patternsExamine Security Manager web logs for potential XSS payloads in HTTP requests. Look for patterns containing '<script>', 'javascript:', or other HTML tags in query parameters. Check logs in the Security Manager\Tomcat\logs or similar log directories.Affected if Logs contain unexpected script tags or encoded payloads in request parameters that were not intentionally submitted by administrators
The environment is affected if Cisco Security Manager is installed with a version lower than 4.24 and its web-based management interface is accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.24
Apply the vendor-provided security updates from Cisco for Security Manager. As a temporary user-level mitigation, avoid clicking untrusted or suspicious links while accessing the management interface.
Security Manager version 4.24
- Ensure you have a current backup of your Cisco Security Manager configuration and data
- Review the Cisco Security Manager 4.24 release notes for any special upgrade requirements or prerequisites
- Download Cisco Security Manager version 4.24 from the Cisco software download center
- Follow the standard Cisco Security Manager upgrade procedure: stop the Security Manager services, run the installer for version 4.24, and follow the on-screen prompts
- After upgrade, verify that the Security Manager services started successfully
- Confirm the version number shows 4.24 in the web-based management interface
- Test that the web interface is functional and accessible
