CVE-2021-23355
If (attacker-controlled) user input is given to the kill function, it is possible for an attacker to execute arbitrary commands.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.20%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
This affects all versions of package ps-kill. If (attacker-controlled) user input is given to the kill function, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization in the index.js file. PoC (provided by reporter): var ps_kill = require('ps-kill'); ps_kill.kill('$(touch success)',function(){});
