Saml Sso For Joomla Extension For Joomla
Monthly
Unauthenticated authentication bypass in miniOrange's SAML Single Sign-On extensions for Joomla (SAML SSO < 11.0.2, SAML SP Login with ADFS < 6.4, and SAML SSO login with Google Apps < 6.4) lets remote attackers log in as any Joomla account, including administrators. The mo_saml_validate_signature() function treats OpenSSL's -1 error return as a successful signature verification, so a crafted SAMLResponse with an attacker-chosen NameID and a deliberately malformed signature bypasses validation entirely. Rated CVSS 4.0 10.0; no public exploit identified at time of analysis, but the flaw is trivially reachable and yields full site takeover.
