Project: SAML SP 2.0 Single Sign On (SSO) - SAML Service Provider [1]
Date: 2021-September-22
Security risk: *Moderately critical* 14∕25
AC:Basic/A:None/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
Vulnerability: Multiple vulnerabilities

Description: 
This module provides a solution to authenticate visitors using existing SAML
providers.

Certain non-default configurations allow a malicious user to login as any
chosen user.

The vulnerability is mitigated by the module's default settings which require
the options "Either sign SAML assertions" and "x509 certificate".

Solution: 
Ensure that the "Either SAML response or SAML assertion must be signed" and
"x509 certificate" options on the dedicated plugin page are both enabled.
