CVE-2020-17457Network attack vector

Stored XSS via PSCU_FILE_INIT error-page injection

Published Mar 17, 2021 · Updated Aug 4, 2024

Stored XSS in Fujitsu ServerView Suite iRMC before 9.62F allows remote authenticated users to execute script in another user's browser. The Save Configuration XML handler stores unsanitized PSCU_FILE_INIT content and inserts it into HTTP error response pages. Exploitation requires valid credentials and a victim to load an affected error page, which runs attacker-controlled script within the victim's iRMC origin.
