Vulnerability Data

OctoPrint provides a web interface for controlling consumer 3D printers. Versions 1.11.3 and below are affected by a vulnerability that allows injection of arbitrary HTML and JavaScript into Action Command notifications and prompts popups generated by the printer. An attacker…

who successfully convinces a victim to print a specially crafted file could exploit this issue to disrupt ongoing prints, extract information (including sensitive configuration settings, if the targeted user has the necessary permissions for that), or perform other actions on behalf of the targeted user within the OctoPrint instance. This issue is fixed in version 1.11.4.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

prevent

Directly requires validation and sanitization of untrusted input (action commands from G-code files) before it is rendered as HTML/JS in notifications.

SI-15 Information Output Filtering good match

prevent

Requires filtering of information prior to output, preventing unsanitized printer-supplied content from being rendered in popups and notifications.

SI-7 Software, Firmware, and Information Integrity partial match

detect

Enables integrity checks on rendered content or detection of unauthorized script injection into the web interface.
