CVE-2026-45556Public exploitNetwork attack vector

Authenticated root execution via WAF path traversal

Published Jun 10, 2026 · Updated Jun 10, 2026

Path traversal in Roxy-WI 8.2.6.4 and earlier allows remote authenticated users to execute commands as root on managed load balancers. The WAF rule save endpoint decodes 92 as a slash, checks only for service and configuration substrings, and moves the supplied body over SSH to the attacker-selected path with passwordless sudo. Group-admin access and a managed Linux load balancer are required; placing a cron file causes its commands to run as root on the next scan.
