Details

As written in the advisory (Markdown source, shown as plain text).

### Vulnerability https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L869-L870 https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L894-L895 The salt is derived from sha256Sum(passphrase). Two encryption operations with the same password will have the same derived key. ### Impact Pre-computation attacks. Severity is considered low for internal uses of this library and high for consumers of this library. ### Patches Jervis will generate a random salt for each password and store it alongside the ciphertext. Upgrade to Jervis 2.2. ### Workarounds None ### References - [NIST SP 800-132: Password-Based Key Derivation](https://csrc.nist.gov/publications/detail/sp/800-132/final)
