Synopsis

Zoho ManageEngine SAML SSO Remote Code Execution

Description

Multiple Zoho ManageEngine OnPremise products use an outdated Apache Santuario (xmlsec) component which fails to properly validate XML signatures of SAML responses received during the authentication flow. By crafting a specific HTTP request containing a malicious XML payload and sending it to the vulnerable product Assertion Consumer (ACS) URL, an attacker could achieve a remote unauthenticated Remote Code Execution (RCE) on the target instance.

Solution

Update to a fixed version of the vulnerable product as described in the vendor security advisory.
