CVE-2021-20374Network attack vector

Credential disclosure via stored Web UI script

Published May 19, 2021 · Updated Sep 16, 2024

Stored cross-site scripting in IBM Maximo Asset Management 7.6.0 and 7.6.1 allows remote attackers to disclose session credentials. IBM has not disclosed the specific field or sanitizer failure; the Web UI stores supplied JavaScript and executes it in a trusted session. The consequence is limited to that session context, and IBM does not identify the submission path needed to place the script.
