How to Fix CVE-2022-2111

To remediate this vulnerability, upgrade all affected Inventree dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

inventree fixed: 0.7.2 
pip install inventree>=0.7.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show inventree

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-2111, inspect your installed packages using pip:

pip show inventree

Analyze the terminal output to locate any version of Inventree in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.2), your application is affected.

Note: The pip show inventree command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

Source Advisory Statement

### 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. ![image](https://user-images.githubusercontent.com/10080325/173549827-af2d7a5c-1359-4d68-a920-dfdd0ccc882e.png) *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" ![image](https://user-images.githubusercontent.com/10080325/173550035-2de4bf01-f0d3-4be8-ac45-6fbcf66a95e7.png) This minimizes risk (e.g. of XSS attacks) by opening the HTML file from the users computer ### References https://huntr.dev/bounties/a0e5c68e-0f75-499b-bd7b-d935fb8c0cd1/ ### For more information If you have any questions or comments about this advisory: * Open an issue in [github](http://github.com/inventree/inventree) * Email us at [security@inventree.org](mailto:security@inventree.org)
