CVE-2021-20444Network attack vector

Credential disclosure via Web UI script injection

Published Feb 18, 2021 · Updated Sep 16, 2024

Cross-site scripting in IBM Maximo for Civil Infrastructure 7.6.2 allows remote attackers to run JavaScript in a trusted Web UI session. The Web UI accepts attacker-controlled content and renders it as executable script, but IBM has not identified the affected field, endpoint, or whether the payload is stored or reflected. A victim must interact with the crafted content; successful execution can alter the interface and disclose credentials available within that session.
