CVE-2019-10754 · GHSA-g24w-373r-5pxg
- Affected
- Maven org.apereo.cas:cas-server-support-oauth-core-api < 6.1.0-RC5
- Fixed in
- 6.1.0-RC5· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 6.1.0-RC5 (pre-release) or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
