GHSA-5379-R78W-42H2

Vulnerability from github – Published: 2021-08-30 16:11 – Updated: 2024-02-10 00:55

Summary

Unlimited transforms allowed for signed nodes

Details

Impact

A malicious SAML payload can require transforms that consume significant system resources to process, thereby resulting in reduced or denied service. This would be an effective way to perform a denial-of-service attack.

Patches

This has been resolved in version 3.1.0. The resolution is to limit the number of allowable transforms to 2.

Vulnerability from cvelistv5 – Published: 2021-08-27 22:05 – Updated: 2024-08-04 01:58

Title

Unlimited transforms allowed for signed nodes

Summary

Passport-SAML is a SAML 2.0 authentication provider for Passport, the Node.js authentication library. Prior to version 3.1.0, a malicious SAML payload can require transforms that consume significant system resources to process, thereby resulting in reduced or denied service. This would be an effective way to perform a denial-of-service attack. This has been resolved in version 3.1.0. The resolution is to limit the number of allowable transforms to 2.

Severity
