CVE-2020-27540 is a critical bash injection vulnerability affecting Rostelecom CS-C2SHW 5.0.082.1 cameras and their firmware. An attacker can exploit this by placing a specially crafted version.json file on an SD card, which the camera automatically processes, allowing arbitrary command execution due to direct insertion of the 'fw-sign' parameter into a bash command.
