Improper verification of cryptographic signature in Keycloak - CVE-2024-8698

Vulnerability identifier: #VU97621

CSH Severity: Medium

CVSS v4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2024-8698

CWE-ID: CWE-347

Exploitation vector: Remote access

Exploit availability: Public exploit is available

The vulnerability allows a remote user to escalate privileges within the application.

The vulnerability exists due to improper validation of SAML signature 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. A remote user can create crafted responses that bypass the validation, potentially leading to privilege escalation or impersonation attacks.
