Summary
Apache CXF from 4.2.0 before 4.2.4, from 4.0.0 before 4.1.9, and before 3.6.13 is affected. A milliseconds and seconds unit mismatch and an inverted comparison make the max_age authentication-freshness check in OidcClientCodeRequestFilter inoperative (CWE-613). Relying parties that use setMaxAgeOffset to enforce re-authentication accept sessions of any age, which bypasses step-up authentication policies.

Description from the CNA
The max_age authentication-freshness check in OidcClientCodeRequestFilter was inoperative due to a milliseconds/seconds unit mismatch and an inverted comparison polarity. Any relying party using setMaxAgeOffset to enforce re-authentication would silently accept sessions of any age, bypassing step-up authentication policies. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
