CVE-2023-32341Network attack vector

Authenticated service interruption via uncontrolled resource consumption

Published Feb 9, 2024 · Updated Aug 2, 2024

Uncontrolled resource consumption in IBM Sterling B2B Integrator allows remote authenticated users to interrupt service. Affected releases are 6.0.0.0 through 6.0.3.8 and 6.1.0.0 through 6.1.2.3; IBM has not disclosed the responsible component or the operation that fails to bound resource use. A low-privileged authenticated network session is required, and successful exploitation exhausts resources until the service becomes unavailable; no data disclosure or modification is reported.
