Detailsinfo

A vulnerability was found in Red Hat Build of Keycloak, JBoss Enterprise Application Platform and Single Sign-On (affected version not known) and classified as problematic. Affected by this issue is some unknown functionality of the component SAML Signature Handler. The manipulation with an unknown input leads to a signature verification vulnerability. Using CWE to declare the problem leads to CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Reference element used to specify the signed element. This flaw allows attackers to create crafted responses that can bypass the validation, potentially leading to privilege escalation or impersonation attacks.

The advisory is shared for download at access.redhat.com. This vulnerability is handled as CVE-2024-8698 since 09/11/2024. The exploitation is known to be difficult. The attack may be launched remotely. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 11/05/2024).
