Summary

Jervis Has Weak Random for Timing Attack Mitigation

Details

Vulnerability

https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L593-L594

Uses java.util.Random() which is not cryptographically secure.

Impact

If an attacker can predict the random delays, they may still be able to perform timing attacks.

Patches

Jervis will use SecureRandom for timing randomization.

Upgrade to Jervis 2.2.

Workarounds

None
