Unrestricted Attachment Upload

High severity GitHub Reviewed Published Jun 15, 2022 in inventree/InvenTree • Updated Jan 27, 2023

Package

pip inventree (pip)

Affected versions

< 0.7.2

Patched versions

0.7.2

Description

Impact

InvenTree allows unrestricted upload of files as attachments to various database fields. Potentially dangerous files (such as HTML files containing malicious javascript) can be uploaded, and (when opened by the user) run the malicious code directly in the users browser.

Note that the upload of malicious files must be performed by an authenticated user account

Solution

The solution for this vulnerability is to ensure that attachment files are downloaded to the local machine before opening, rather than opening the file in the current browser context.

Patches

  • The issue is addressed in the upcoming 0.8.0 release
  • This fix will also be back-ported to the 0.7.x branch, applied to the 0.7.2 release

Workarounds

Users can alleviate risk of opening malicious files by right-clicking on the attachment link and selecting "Save link as"

This minimizes risk (e.g. of XSS attacks) by opening the HTML file from the users computer

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
