CVE-2024-32651
10.0
CRITICAL · CVSS 3.1 · EPSS 83.6% (pctl 100)
Patch early
EPSS 83.6% — above the 10% action threshold.
Description
changedetection.io is an open source web page change detection, website watcher, restock monitor and notification service. There is a Server Side Template Injection (SSTI) in Jinja2 that allows Remote Command Execution on the server host. Attackers can run any system command without any restriction and they could use a reverse shell. The impact is critical as the attacker can completely takeover the server machine. This can be reduced if changedetection is behind a login page, but this isn't required by the application (not by default and not enforced).
