Vulnerability

https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L869-L870

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
