Technical details

A stored cross-site scripting (XSS) vulnerability exists in the Web UI of IBM Sterling B2B Integrator and IBM Sterling File Gateway. The flaw is caused by improper neutralization of user-supplied input during web page generation (CWE-79). A remote attacker with high privileges (PR:H) can exploit this by embedding arbitrary JavaScript code into the application's interface. When other users view the affected pages, the script executes in their browser context, potentially leading to the disclosure of session credentials or unauthorized actions within a trusted session. IBM has released patches (6.2.0.6_1, 6.2.1.2, and 6.2.2.1) to address this issue.
