LoginTime-of-check Time-of-use (TOCTOU) Race Condition vulerability in Foscam R2C IP camera running System FW <= 1.13.1.6, and Application FW <= 2.91.2.66, allows an authenticated remote attacker with administrator permissions to execute arbitrary remote code via a malicious firmware patch. The impact of this vulnerability is that the remote attacker could gain full remote access to the IP camera and the underlying Linux system with root permissions. With root access to the camera's Linux OS, an attacker could effectively change the code that is running, add backdoor access, or invade the privacy of the user by accessing the live camera stream.

CWE-367 Time-of-check Time-of-use (TOCTOU) Race Condition
The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
