CVE-2024-8698: Improper Verification of Cryptographic Signature
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.
AI Analysis
Technical Summary
CVE-2024-8698 is a vulnerability in the SAML signature validation logic within the Keycloak XMLSignatureUtil class, where the method incorrectly determines the scope of the signature based on its XML document position rather than the Reference element. This flaw can be exploited by attackers to craft SAML responses that bypass signature validation, leading to potential privilege escalation or impersonation attacks. The vulnerability affects Red Hat Single Sign-On 7.6 on RHEL 7 and 8. Red Hat has issued security advisories RHSA-2024:6878 and RHSA-2024:6879, releasing version 7.6.11 of Red Hat Single Sign-On that includes the fix. The advisories confirm the availability of an official patch and provide instructions for applying the update.
Potential Impact
Successful exploitation of this vulnerability allows attackers to bypass SAML signature validation, potentially leading to privilege escalation or impersonation within affected Red Hat Single Sign-On deployments. This could compromise authentication integrity and allow unauthorized access. The CVSS v3.1 base score is 7.7 (high severity), reflecting network attack vector, high confidentiality impact, and limited privileges required for exploitation.
Mitigation Recommendations
An official security update is available from Red Hat that fixes this vulnerability. Red Hat Single Sign-On 7.6.11 packages for RHEL 7 and RHEL 8 include the patch addressing CVE-2024-8698. Users should apply these updates promptly after ensuring all prior relevant errata have been applied. Refer to Red Hat advisories RHSA-2024:6878 and RHSA-2024:6879 and the update instructions at https://access.redhat.com/articles/11258 for detailed guidance. No additional mitigation is required beyond applying the official patch.
