CVE-2022-0853Public exploitNetwork attack vector

Information disclosure via JBoss client memory leak

Published Mar 11, 2022 · Updated Aug 2, 2024

Memory leak in JBoss-client 1.7 allows remote attackers to cause information disclosure by repeatedly using UserTransaction. The EJB remote transaction client retains memory after repeated UserTransaction operations instead of releasing it at the end of its effective lifetime. Reaching the condition requires repeated transaction activity; exhaustion can interrupt service and expose residual process data.
