CVE-2016-6558
A command injection vulnerability exists in apply.cgi on the ASUS RP-AC52 access point, firmware version 1.0.1.1s and possibly earlier, web interface specifically in the action_script parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.50%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A command injection vulnerability exists in apply.cgi on the ASUS RP-AC52 access point, firmware version 1.0.1.1s and possibly earlier, web interface specifically in the action_script parameter. The action_script parameter specifies a script to be executed if the action_mode parameter does not contain a valid state. If the input provided by action_script does not match one of the hard coded options, then it will be executed as the argument of either a system() or an eval() call allowing arbitrary commands to be executed.
