CVE-2022-45028Public exploitNetwork attack vector

Stored XSS via unsanitized log input

Published Dec 13, 2022 · Updated Apr 22, 2025

Stored XSS in Arris NVG443B 9.3.0h3d36 allows remote attackers to execute script in a user's browser via /cgi-bin/logs.ha. The logging handler accepts attacker-controlled POST data and later renders it as HTML without neutralizing executable markup. Exploitation is unauthenticated but requires a user to view the stored content; code runs in that user's web context and can read or alter page data.
