Detailsinfo

A vulnerability was found in node SAML up to 4.0.0-beta4. It has been classified as problematic. This affects an unknown functionality of the component XML Element Handler. The manipulation with an unknown input leads to a signature verification vulnerability. CWE is classifying the issue as CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. This is going to have an impact on confidentiality. The summary by CVE is:

node SAML is a SAML 2.0 library based on the SAML implementation of passport-saml. 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 node-saml version 4.0.0-beta5 or newer. Disabling SAML authentication may be done as a workaround.

The weakness was presented 10/14/2022 as GHSA-5p8w-2mvw-38pv. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2022-39300 since 09/02/2022. Neither technical details nor an exploit are publicly available.

Upgrading to version 4.0.0-beta5 eliminates this vulnerability. Applying the patch c1f275c289c01921e58f5c70ce0fdbc5287e5fbe is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
