Authenticated command execution via malicious packet content
Published Jun 13, 2025 · Updated Jun 17, 2025
OS command injection in Hikvision DS-3WAP SI access points allows remote authenticated users to execute arbitrary commands via crafted packets. The public advisory does not identify the packet field or firmware handler; it states that insufficient input validation passes malicious command content for execution. Successful exploitation requires valid high-privilege device credentials and runs commands on the appliance without further user interaction.
