Browser script execution via undisclosed input handling

Published Feb 24, 2022 · Updated Aug 3, 2024

Cross-site scripting in HPE OneView Global Dashboard before 2.5 allows remote attackers to execute script in a user's browser. HPE's bulletin does not identify the affected page, parameter, rendering path, or input-neutralization error that admits the script. Exploitation is unauthenticated but requires user interaction and can expose or alter browser-accessible data without interrupting the appliance.
