represented a more severe threat — an unauthenticated remote code execution vulnerability in the web server of many Hikvision IP cameras and NVRs. Due to insufficient input validation, an attacker could send specially crafted messages to execute arbitrary commands on vulnerable devices. Hikvision publicly disclosed and patched this vulnerability in September 2021, distributing updated firmware through the company‘s website.
Modifying firmware carries inherent risks. Protect your hardware by following these industry best practices.
