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.
-
Identify Palantir Gotham Chat IRC installationLocate the Palantir Gotham Chat IRC helper component in your environment. This may be listed as a module, service, or add-on within the Palantir Gotham deployment.Affected if The Chat IRC helper component is present in the environment
-
Determine installed version of Palantir Gotham Chat IRCRetrieve the version number of the installed Chat IRC helper. Consult Palantir documentation for the specific method to obtain the version (such as looking in the product's about section, version log, or component metadata).Affected if A version number is returned that is lower than 30221005.210011.9242
-
Verify IRC chat functionality is in useDetermine whether the IRC chat feature within Palantir Gotham Chat is enabled or has been configured for use. Check for active IRC connections or IRC-related configuration files.Affected if The IRC chat feature is enabled or configured in the deployment
-
Confirm certificate validation behaviorIf the IRC chat makes outbound connections, inspect network traffic or SSL/TLS handshake behavior to confirm whether the certificate host validation is occurring (the vulnerability exists if host matching is not validated).Affected if Network connections are made without proper certificate host validation
You are affected if Palantir Gotham Chat IRC is installed with a version lower than 30221005.210011.9242 and the IRC chat feature is in use.
