User impersonation via unsigned SAML response
Published Jun 3, 2022 · Updated Aug 3, 2024
Authentication bypass in Xecurify miniOrange SAML SSO paid modules before fixed releases allows remote attackers to impersonate users via unsigned SAML responses. The SAML SSO handler skips signature verification when an assertion is unsigned, allowing a captured response to be modified with an existing username and role. An attacker needs a method to intercept and alter HTTP SAML traffic; successful use can grant ordinary or administrative account access and alter site data.
