CVE-2022-39299
Signature bypass via multiple root elements
描述
### 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 passport-saml 3.2.2 or newer. The issue was also present in the beta releases of `node-saml` before v4.0.0-beta.5. ### Workarounds Disable SAML authentication. ### References _Are there any links users can visit to find out more?_ ### For more information If you have any questions or comments about this advisory: * Open a discussion in the [node-saml repo](https://github.com/node-saml/node-saml/discussions) ### Credits * Felix Wilhelm of Google Project Zero
