Technical details

An authorization bypass vulnerability (CWE-639) exists in IBM Sterling B2B Integrator and IBM Sterling File Gateway. The flaw is rooted in improper access control where the application relies on user-controlled keys or specially crafted HTTP requests to validate identity. A remote, unauthenticated attacker can exploit this by sending a tailored HTTP request to the server, bypassing authentication mechanisms to gain unauthorized access to sensitive data. The vulnerability affects versions 6.2.0.0 through 6.2.2.0_1 and has been addressed in patches 6.2.0.6, 6.2.1.2, and 6.2.2.1.

Affected products
