CVE-2021-20554Network attack vector

Credential disclosure via unneutralized Web UI scripts

Published Sep 30, 2021 · Updated Sep 17, 2024

Cross-site scripting in IBM Sterling Order Management 9.4, 9.5, and 10.0 allows remote attackers to disclose session credentials. The Web UI accepts embedded JavaScript without neutralizing it, although IBM has not identified the affected page or input parameter. A victim must interact with the attack mechanism; the script then runs within a trusted session and can alter the interface or expose credentials.
