Jervis has Deterministic AES IV Derivation from Passphrase
### Vulnerability https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L866-L874 https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L891-L900 Same passphrase + same plaintext = same ciphertext (IV reuse) ### Impact Severity is considered low for internal uses of this library but if there's any consumer using these methods directly then this is considered high. Significant reduction in the security of the encryption scheme. Pattern analysis becomes possible. ### Patches Random IV will be generated and prepended to the ciphertext. Upgrade to Jervis 2.2. ### Workarounds None
