VAR-202511-0549
Vulnerability from variot - Updated: 2025-12-19 22:54A command injection vulnerability exists in the ToToLink A720R Router firmware V4.1.5cu.614_B20230630 within the cloudupdate_check binary, specifically in the sub_402414 function that handles cloud update parameters. User-supplied 'magicid' and 'url' values are directly concatenated into shell commands and executed via system() without any sanitization or escaping. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device. TOTOLINK of A720R Firmware contains a command injection vulnerability.Information may be obtained and information may be tampered with. The TOTOLINK A720R is a wireless router launched by TOTOLINK, a Chinese electronics company. It features dual-band Wi-Fi and emphasizes high-speed network and signal coverage. This vulnerability stems from the unverified magicid and url parameters in the cloudupdate_check binary file. Detailed vulnerability information is currently unavailable
