CVE-2020-14967
RSA PKCS#1 decryption vulnerability with prepending zeros in jsrsasign
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon NVD, GHSA.
Description
An issue was discovered in the jsrsasign package before 8.0.18 for Node.js. Its RSA PKCS1 v1.5 decryption implementation does not detect ciphertext modification by prepending '\0' bytes to ciphertexts (it decrypts modified ciphertexts without error). An attacker might prepend these bytes with the goal of triggering memory corruption issues.
