CVE-2020-4380Network attack vector

Authenticated JavaScript execution via tampered Web UI request

Published Jun 11, 2020 · Updated Sep 16, 2024

Cross-site scripting in IBM Workload Scheduler 9.3.0.4 and earlier allows remote authenticated users to execute JavaScript in the Web UI. After loginit, a user can modify an outgoing Dynamic Workload Console request sent by GET or POST so its response executes the injected script. IBM has not identified the affected parameter or failed output-encoding operation; exploitation requires a trusted browser session and allows credential disclosure.
