What is CVE-2024-28237?
CVE-2024-28237 is a medium-severity cross-site scripting vulnerability in OctoPrint, published on 18 Mar 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
OctoPrint provides a web interface for controlling consumer 3D printers. OctoPrint versions up until and including 1.9.3 contain a vulnerability that allows malicious admins to configure or talk a victim with administrator rights into configuring a webcam snapshot URL which when tested through the "Test" button included in the web interface will execute JavaScript code in the victims browser when attempting to render the snapshot image. An attacker who successfully talked a victim with admin rights into performing a snapshot test with such a crafted URL could use this to retrieve or modify sensitive configuration settings, interrupt prints or otherwise interact with the OctoPrint instance in a malicious way. The vulnerability is patched in version 1.10.0rc3. OctoPrint administrators are strongly advised to thoroughly vet who has admin access to their installation and what settings they modify based on instructions by strangers.
Weakness: CWE-79
