CVE-2022-48066Public exploitNetwork attack vector

Unauthenticated management access via crafted cookie

Published Jan 27, 2023 · Updated Mar 28, 2025

Authentication bypass in TOTOLINK A830R 4.1.2cu.5182 allows remote attackers to access protected router functionality via a crafted cookie. The global.so component accepts the crafted cookie as sufficient authentication, although public evidence does not disclose the cookie name or exact validation error. No credentials or user interaction are required, and successful requests cross the management interface's authentication boundary.
