CVE-2019-10755

Name of the Vulnerable Software and Affected Versions pac4j-saml versions 3.X

Description The issue arises from the use of the apache commons-lang3 RandomStringUtils class in SAML2Utils.java to generate SAML identifiers. This class uses a pseudorandom number generator (PRNG) algorithm that is not cryptographically strong, making the identifiers predictable.

Recommendations For pac4j-saml version 3.X, consider using a cryptographically strong random number generator to generate SAML identifiers as a replacement for the current implementation.
