CVE-2022-39299
A remote attacker may be able to bypass SAML authentication on a website using passport-saml.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Passport-SAML is a SAML 2.0 authentication provider for Passport, the Node.js authentication library. 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. Users should upgrade to passport-saml version 3.2.2 or newer. The issue was also present in the beta releases of `node-saml` before version 4.0.0-beta.5. If you cannot upgrade, disabling SAML authentication may be done as a workaround.
