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.

Affected Software

Name Vendor Start Version End Version
Guacamole Apache 1.2.0 (including) 1.2.0 (including)
Guacamole Apache 1.3.0 (including) 1.3.0 (including)
