Apache Guacamole 1.2.0 and 1.3.0 do not properly validate responses received from a SAML identity provider. If SAML support is enabled, this may allow a malicious user to assume the identity of another Guacamole user.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
