Описание

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
