CVE-2019-10754: Apereo Central Authentication Service

High severity, CVSS 8.1. EPSS: 1.8% chance of exploitation in the next 30 days.

Multiple classes used within Apereo CAS before release 6.1.0-RC5 makes use of apache commons-lang3 RandomStringUtils for token and ID generation which makes them predictable due to RandomStringUtils PRNG's algorithm not being cryptographically strong.

Affected products

• Apereo Central Authentication Service: up to and including 6.0.5.1; version 6.1.0 only
