The vulnerability of the setIptvCfg() function in the /cgi-bin/cstecgi.cgi script of the TOTOLINK A3300R router’s microprogramming software allows a intruder to execute arbitrary commands.

The vulnerability of the setIptvCfg function in the /cgi-bin/cstecgi.cgi script of the TOTOLINK A3300R router’s microprogramming system is related to the failure to take measures to neutralize special elements during the processing of the vlanPriLan3 parameter. Exploiting this vulnerability allow...
