CVE-2023-27000Public exploitNetwork attack vector

Stored script execution via unsanitized CSV import

Published Jan 9, 2024 · Updated Jul 9, 2026

Stored cross-site scripting in NETSCOUT nGeniusONE 6.3.4 allows remote attackers to execute script through a crafted imported CSV file. The application stores an imported CSV column without sanitization and renders its name on the Profile and Exclusion List pages without output encoding. A user must view an affected page; the script then runs in that user’s browser context and can read or alter data available to that session.
