Server Side Template Injection Vulnerability Allows Remote Command Execution

CVE-2024-32651

What is CVE-2024-32651?

The vulnerability within changedetection.io leverages a Server Side Template Injection (SSTI) in the Jinja2 templating engine, which could allow an attacker to execute arbitrary system commands on the server. This serious flaw potentially enables unauthorized access to the server, as attackers may run any command without restrictions, including the ability to deploy a reverse shell. While some mitigation exists if changedetection.io is implemented behind a login interface, this security measure is not required by default and therefore does not provide comprehensive protection. It is crucial for users and administrators of changedetection.io to be aware of this vulnerability and implement appropriate security measures to safeguard their systems.
