Command Injection in killport

Source: GitHub Advisory Database (reviewed) High CVE-2021-23360

Packages

Ecosystem	Package	Affected	Fixed in
npm	killport	< 1.0.2	1.0.2

Details

As written in the advisory (Markdown source, shown as plain text).

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.
