CVE-2021-41570Network attack vector

Authenticated script execution via unsanitized configuration fields

Published Apr 19, 2022 · Updated Aug 4, 2024

Cross-site scripting in Veritas NetBackup OpsCenter and OpsCenter Analytics 9.1 and earlier allows remote authenticated users to execute scripts. The Settings/Configuration Add operation fails to neutralize script content supplied in the master server name, display name, user name, or password field. An authenticated user must submit a crafted value and another user must render it; the script can read or alter data available to the victim's browser.
