CVE-2024-7701

Encrypted-data disclosure via single-round SHA-256 key derivation

Published Dec 15, 2024 · Updated Dec 16, 2024

Insufficient key derivation in Percona Toolkit 3.6.0 allows attackers with an encrypted file to brute-force its password offline. The pt-secure-collect encryptorCmd function hashes the supplied password once with SHA-256 and uses the 32-byte digest directly as the AES key, with a zero IV. Possession of ciphertext is required; successful guessing reveals the collected database and system data without altering it.
