What is CVE-2022-29078?

The ejs (Embedded JavaScript templates) package version 3.1.6 for Node.js is susceptible to server-side template injection. This occurs when the 'settings[view options][outputFunctionName]' is manipulated, allowing an attacker to replace the outputFunctionName option with a malicious OS command. This command is executed during the process of template compilation, potentially compromising the server's security.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
