CVE-2023-3034Network attack vector

Reflected XSS via unneutralized admin mode parameter

Published Jun 28, 2023 · Updated Nov 6, 2024

Reflected XSS in BKG Professional NtripCaster 2.0.44 and earlier allows remote attackers to run script via the /admin mode parameter. The /admin request handler places the mode query value into generated HTML without neutralizing script-capable input. A user must open a crafted request for the reflected script to execute in that browser's affected-origin context; no data reading or service interruption is reported.
