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 · uneditedOpen redirect vulnerability in the Administrative Console in CA Arcot WebFort Versatile Authentication Server (VAS) before 6.2.5 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.
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 confidenceOpen redirect vulnerability in the Administrative Console of CA Arcot WebFort Versatile Authentication Server (VAS) prior to version 6.2.5 allows remote attackers to craft malicious URLs that redirect authenticated users to arbitrary external websites, facilitating credential phishing and social engineering attacks.

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.
-
Confirm CA Arcot WebFort VAS is installedLook for the product in your installed applications, services, or check common installation directories such as /opt/arcot or C:\Program Files\CA\Arcot on Windows systemsAffected if The product is present on the system
-
Identify the installed versionCheck the version of CA Arcot WebFort Versatile Authentication Server by reviewing the product documentation, using the product's built-in version check command, or examining version information in the installation directory or registryAffected if The installed version is 6.2.4 or lower
-
Verify Administrative Console is accessibleDetermine if the Administrative Console web interface is exposed by checking if the console port (typically 8080 or 8443) is listening and accessible from network locationsAffected if The Administrative Console is reachable over the network
-
Test for open redirect behaviorIf the Administrative Console is accessible, attempt to access a crafted URL such as /admin/console?redirect=http://example.com to observe whether the application permits redirection to external domainsAffected if The application redirects to arbitrary external URLs without validation
A user is affected if CA Arcot WebFort VAS version 6.2.4 or lower is installed with the Administrative Console accessible and the redirect parameter permits arbitrary external URLs.
