Unauthenticated code execution via dangerous file upload
Published Jun 11, 2026 · Updated Jun 11, 2026
Unrestricted file upload in Limatek LimRAD NAC before 5.5.7.3.9 allows remote attackers to include and execute uploaded code. The public advisory identifies dangerous file-type handling as the weakness but does not disclose the upload endpoint, filename checks, storage path, or execution trigger. No authentication is required, and successful exploitation gives code execution on the network-access-control appliance.
