How to Fix CVE-2019-10047

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

pydio fixed: Latest secure release 
pip install pydio>=Latest secure release
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 pydio

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2019-10047, inspect your installed packages using pip:

pip show pydio

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

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Pydio, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A stored XSS vulnerability exists in the web application of Pydio through 8.2.2 that can be exploited by levering the file upload and file preview features of the application. An authenticated attacker can upload an HTML file containing JavaScript code and afterwards a file preview URL can be used to access the uploaded file. If a malicious user shares an uploaded HTML file containing JavaScript code with another user of the application, and tricks an authenticated victim into accessing a URL that results in the HTML code being interpreted by the web browser, then the included JavaScript code is executed under the context of the victim user session.
