CVE-2025-68703

Jervis has a Salt for PBKDF2 derived from password

8.7 HighFix available

Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, the salt is derived from sha256Sum(passphrase). Two encryption operations with the same password will have the same derived key. This vulnerability is fixed in 2.2.

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
