2. Vulnerability details
TOTOLink T10 V5.9c.5061_B20200511 was discovered to contain a command injection vulnerability in the “Main” function. This vulnerability allows attackers to execute arbitrary commands via the QUERY_STRING parameter.
We can see that the os will get QUERY_STRING
without filter splice to the string echo QUERY_STRING:%s >/tmp/download
and execute it. So, If we can control the QUERY_STRING
, it can be command injection.
