Restricted service access via path traversal
Published Apr 29, 2026 · Updated Apr 29, 2026
Path traversal in SonicWall SonicOS allows remote authenticated users to interact with normally restricted network services. SonicWall has not disclosed the affected request handler or how it processes attacker-controlled path input when selecting a backend service. The post-authentication gate limits reachability, while successful traversal crosses intended service restrictions; no more specific consequence is published.
