Summary

An Open Redirect vulnerability was discovered in the SAML Single Sign-On functionality due to insufficient validation of a user-controlled redirection parameter. An unauthenticated attacker can craft a request to the SAML sign-in endpoint and poison the cached SAML redirection for other users who subsequently initiate SAML Single Sign-On, enabling phishing and credential-theft attacks, as well as disrupting SAML authentication for all affected users.

Risk Assessment

The organization is exposed to phishing attacks and credential theft, as well as disruptions to SAML authentication, which can lead to loss of trust and data security breaches.

Recommendation

Immediately update the software to a version that fixes the validation of the redirection parameter in the SAML Single Sign-On functionality. Until the update is applied, temporarily disable or restrict access to the SAML endpoint.
