Authenticated command injection via crafted packets
Published Jul 31, 2026 · Updated Jul 31, 2026
OS command injection in Hikvision networking products 1.1.6601 build251223 and earlier allows remote authenticated users to execute commands. The devices accept crafted packets containing command text without sufficient input validation, but Hikvision has not disclosed the affected interface, packet field, or command-building routine. High-privilege credentials and network access are required; successful exploitation executes arbitrary commands with the device's authority.
