OS command injection in Linksys E1000/E1200/E3200 apply.cgi ping_ip
CVE-2013-3307 is an OS command injection vulnerability in Linksys E1000 devices through 2.1.02, E1200 devices before 2.0.05, and E3200 devices through 1.0.04. The flaw is exposed via the apply.cgi endpoint on TCP port 52000, where the ping_ip parameter is insufficiently sanitized and accepts shell metacharacters. An attacker can supply crafted input to ping_ip so that the device executes unintended operating system commands in the underlying shell context.
