CVE-2021-39087Network attack vector

Sensitive information exposure via improper permissions

Published Aug 16, 2022 · Updated Sep 17, 2024

Improper permission controls in IBM Sterling B2B Integrator 6.0.0.0 through 6.1.1.1 allow remote authenticated users to obtain sensitive information. The Dashboard UI applies incorrect authorization checks, allowing an authenticated account to read information outside its intended permission scope. Access requires a valid account and network reachability to the Dashboard UI; the documented impact is information disclosure without integrity or availability effects.
