CVE-2019-20494

Information disclosure via predictable random number sequence

Published Mar 17, 2020 · Updated Aug 5, 2024

Predictable output in Cpanel::Rand::Get in cPanel before 82.0.18 allows local users to obtain limited sensitive information. The random-number routine can emit a repeatable number sequence, so values expected to be unpredictable can be anticipated; public records do not disclose its seeding or call sites. Exploitation requires local low-privileged access, and the published assessment limits impact to confidentiality without integrity or availability effects.
