Public Exploit
Arbitrary Command Injection

Description

This affects the package killport before 1.0.2. If (attacker-controlled) user input is given, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization. Running this PoC will cause the command touch success to be executed, leading to the creation of a file called success.
