CVE-2020-4299Network attack vector

Authenticated sensitive-information disclosure via crafted HTTP request

Published May 14, 2020 · Updated Sep 16, 2024

Information disclosure in IBM Sterling B2B Integrator 5.2.0.0 through 6.0.3.1 allows remote authenticated users to read sensitive data. IBM identifies a crafted request to the GPM web application, but does not disclose which request element is mishandled or how the response exposes data. Low-privileged authenticated network access is required, and the documented consequence is limited to confidentiality loss.
