How the attack worksNo clicks needed

This is a OS Command Injection (CWE-78) vulnerability in Reolink Multiple IP Cameras. On Reolink RLC-410W, C1 Pro, C2 Pro, RLC-422W, and RLC-511W devices through 1.0.227, an authenticated admin can use the "TestEmail" functionality to inject and run OS commands as root, as demonstrated by shell metacharacters in the addr1 field. Exploitation requires remote network access, low attack complexity, an administrative account, and no user interaction required.
