AI-suggested
To mitigate this vulnerability, European organizations should: 1) Restrict and monitor privileged user access rigorously, implementing least privilege principles and strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of insider threats or compromised accounts. 2) Conduct thorough input validation and output encoding on all user-supplied data within the IBM Sterling B2B Integrator UI to prevent injection of malicious scripts. 3) Apply any available vendor patches or updates promptly once released by IBM. 4) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the web interface. 5) Regularly audit and review logs for suspicious activities related to UI modifications or script injections. 6) Educate administrators and privileged users about the risks of XSS and safe usage practices. 7) Consider network segmentation to isolate B2B integration platforms from general user networks to limit exposure.
Description
IBM Sterling B2B Integrator and IBM Sterling File Gateway 6.0.0.0 through 6.1.2.6 and 6.2.0.0 through 6.2.0.4 is vulnerable to stored cross-site scripting. This vulnerability allows a privileged user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
