Drag and Pwnd: Leverage ASCII characters to exploit VS Code

Summary

This article details how control characters, specifically SOH, STX, EOT, and ETX, can be leveraged to exploit vulnerabilities in VS Code. These characters, not intended for code execution, can trigger unintended actions in modern terminal emulators.

IFF Assessment

FOE

The article describes a method to exploit a vulnerability, which poses a risk to users and systems.

Severity

7.5 High (AI Estimated)

This score reflects a High severity. The vulnerability can be exploited remotely through a specific vector (manipulating control characters in VS Code's terminal). The impact includes potential code execution or unauthorized actions within the VS Code environment.

Defender Context

Defenders should be aware of how seemingly innocuous characters within code or data files can be weaponized to trigger vulnerabilities in development tools like VS Code. This highlights the importance of robust input sanitization and validation, even for control characters, and monitoring for unusual terminal behavior.
