jsrsasign is vulnerable to Improper Verification of Cryptographic Signature
82
High Risk
This Affects:
jsrsasignTL;DR
Affected versions of jsrsasign are vulnerable to improper validation of cryptographic parameters during signature processing. The library does not sufficiently validate certain parameters when handling DSA/ECDSA operations, which could allow specially crafted inputs to bypass expected verification checks. This may enable an attacker to forge or incorrectly validate signatures under specific conditions.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
jsrsasign is vulnerable to Improper Verification of Cryptographic Signature in versions 0.0.1 - 11.1.0.
How to fix this
Upgrade the jsrsasign library to the patch version.
