Vulnerability from github – Published: 2022-10-12 22:05 – Updated: 2022-10-14 19:48
VLAI?
Summary
Signature bypass via multiple root elements
Details

Impact

A remote attacker may be able to bypass SAML authentication on a website using passport-saml. A successful attack requires that the attacker is in possession of an arbitrary IDP signed XML element. Depending on the IDP used, fully unauthenticated attacks (e.g without access to a valid user) might also be feasible if generation of a signed message can be triggered.

Patches

Users should upgrade to node-saml v4.0.0-beta5 or newer.

Workarounds

Disable SAML authentication.
