Kerentanan Use of Password Hash With Insufficient Computational Effort pada jahlives openssl encrypt. Skor CVSS 3.1 5.5 (Medium) menurut NVD.

Deskripsi (NVD)

openssl_encrypt versions before 1.4.6 contain a key derivation flaw in sequential XOR composition mode where the last stage cancels out during key generation. When configured with a single KDF and no prior hashing stage, attackers can bypass memory-hard key derivation and perform offline password cracking at SHA-256 speed instead of the configured KDF cost.
