CVE-2021-35205Network attack vector

Authenticated open redirect via redirector

Published Sep 30, 2021 · Updated Aug 4, 2024

Open redirect in NETSCOUT Systems nGeniusONE 6.3.0 build 1196 allows remote authenticated users to send users to untrusted sites via the redirector. NETSCOUT identifies the redirector as the affected locus but has not published the input, request path, or validation error that permits the destination change. Low-privileged access and user interaction are required, and the bounded result is browser navigation to an untrusted site.
