CVE-2022-24772 Information

Description

Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0 RSA PKCS1 v1.5 signature verification code does not check for tailing garbage bytes after decoding a DigestInfo ASN.1 structure. This can allow padding bytes to be removed and garbage data added 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.
