Vulnerability from github – Published: 2022-03-18 23:09 – Updated: 2022-03-18 23:09

Summary

Improper Verification of Cryptographic Signature in node-forge

Details

Impact

RSA PKCS#1 v1.5 signature verification code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used.

Patches

The issue has been addressed in node-forge 1.3.0.

CVE-2022-24771 (GCVE-0-2022-24771)

Vulnerability from cvelistv5 – Published: 2022-03-18 13:25 – Updated: 2025-04-23 18:46

Title

Improper Verification of Cryptographic Signature in node-forge

Summary

Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0, RSA PKCS#1 v1.5 signature verification code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used. The issue has been addressed in `node-forge` version 1.3.0. There are currently no known workarounds.
