Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-884p-74jh-xrg2. Ths link is maintained to preserve external references.
Original Description
A Code Injection exists in tree-kill on Windows which allows a remote code execution when an attacker is able to control the input into the command, which is executed without any check. The issue arises here: https://github.com/pkrumins/node-tree-kill/blob/master/index.js#L20 . While the Linux part is sanitized, the Windows on simply uses the + operand to concatenate the input into exec()
Steps To Reproduce:
Create the following PoC file:
// poc.js
var kill = require('tree-kill');
kill('3333332 & echo "HACKED" > HACKED.txt & ');
Execute the following commands in another terminal:
npm i tree-kill # Install affected module
dir # Check *HACKED.txt* doesn't exist
node poc.js # Run the PoC
dir # Now *HACKED.txt* exists :)
A new file called HACKED.txt will be created, containing the HACKED string.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
Probability that this vulnerability will be exploited in the wild within the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
