Description: Summary
The application allows users to upload files with scripts in the filename parameter. As a result, a malicious user can upload a script file to the system. When users in the application use the "Diff or Compare" functionality, they are affected by a Stored Cross-Site Scripting vulnerability.

I found a Stored Cross-Site Scripting vulnerability in the "Diff or Compare" functionality. This issue occurs because the upload functionality allows users to upload files with special characters such as <, >, /, and " in the filename.

PoC
Complete instructions, including specific configuration details, to reproduce the vulnerability.
On MobSF version 4.2.8, I clicked on "Unload & Analyze" button.
I uploaded zip file as a name test.zip.
I used an intercepting proxy tool while uploading a file and changed the value of the filename parameter from test.zip to test.zip. This means I uploaded a file and set its name to a script value. As a result, the server allowed the file to be uploaded successfully.
I accessed /recent_scans/ and found a file named test.zip in the recent scans. Then, I clicked on the "Differ or Compare" button."
I found that the application requires selecting a file to compare, and I selected the file test.zip
I found tha...
