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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
