Overview

CVE-2023-40178 is a medium-severity vulnerability. It was published on August 23, 2023 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Node-SAML is a SAML library not dependent on any frameworks that runs in Node. The lack of checking of current timestamp allows a LogoutRequest XML to be reused multiple times even when the current time is past the NotOnOrAfter. This could impact the user where they would be logged out from an expired LogoutRequest. In bigger contexts, if LogoutRequests are sent out in mass to different SPs, this could impact many users on a large scale. This issue was patched in version 4.0.5.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
