| 描述 | A vulnerability was found in Totolink A3300R 17.0.0cu.557_b20221024 . Affected by this vulnerability is the function sub_410F24 of the component cstecgi.cgi . The manipulation of the argument qos_up_bw with an unknown input leads to a command injection vulnerability.We found a Command Injection vulnerability in shttpd , allows remote attackers to execute arbitrary OS commands from a crafted request.In sub_410F24 function, it reads in a user-provided parameter lanIp and passes its value to Uci_Set_Str function.However ,the value of the qos_up_bw is inserted into v11 using snprintf,and the value of v11 will be handled by the function CsteSystem.Finally,the command will be executed by execv() in CsteSystem. |
