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. The JPA OAuth2 authorization code grant provider consumes codes non-atomically, a time-of-check time-of-use race condition (CWE-367). A remote attacker without privileges can send concurrent token exchange requests with one authorization code and obtain multiple valid access tokens. The race depends on timing against a shared database using READ_COMMITTED isolation.

Description from the CNA

Improper enforcement of single-use authorization code semantics in the JPA OAuth2 authorization code grant provider in Apache CXFallows a remote attacker to obtain multiple valid access tokens from a single authorization code via concurrent token exchange requests that race the non-atomic find-then-delete operation against a shared relational database under READ_COMMITTED isolation. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fixes this issue.
