Description

MyScreenTools v2.2.1.0 contains a critical OS command injection vulnerability in the GIF compression tool. The application fails to properly sanitize user-supplied file paths before passing them to cmd.exe, allowing attackers to execute arbitrary system commands with the privileges of the user running the application. The vulnerability exists in the CMD() function within GIFSicleTool\Form_gif_sicle_tool.cs, which constructs shell commands by concatenating unsanitized user input (file paths) and executes them via cmd.exe.

Attack-Flow Graph

Executive Summary

This vulnerability is a critical OS command injection in MyScreenTools v2.2.1.0's GIF compression tool. It occurs because the application does not properly sanitize user-supplied file paths before passing them to the Windows command shell (cmd.exe). As a result, an attacker can inject and execute arbitrary system commands with the same privileges as the user running the application. The issue is located in the CMD() function in the GIFSicleTool\Form_gif_sicle_tool.cs file, where shell commands are constructed by concatenating unsanitized user input.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary system commands on the affected system with the privileges of the user running MyScreenTools. This could lead to unauthorized access, data theft, system compromise, or further attacks depending on the user's permissions and the commands executed.
