An issue was discovered on Moxa AWK-3121 1.14 devices. The Moxa AWK 3121 provides ping functionality so that an administrator can execute ICMP calls to check if the network is working correctly. However, the same functionality allows an attacker to execute commands on the device. The POST parameter "srvName" is susceptible to this injection. By crafting a packet that contains shell metacharacters, it is possible for an attacker to execute the attack.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
