CVE-2022-24771 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.72% chance of exploitation in the next 30 days.

Description

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.
