Assigner: VulnCheck

Description
Claude HUD through 0.0.12, patched in commit 234d9aa, contains a command injection vulnerability that allows local attackers to execute arbitrary commands by manipulating the COMSPEC environment variable. Attackers can set COMSPEC to an arbitrary binary path before claude-hud performs its version check, causing execFile() to execute the attacker-supplied executable with cmd.exe arguments, resulting in arbitrary code execution on Windows systems.

Executive Summary

This vulnerability exists in Claude HUD versions up to 0.0.12 and is caused by a command injection flaw. Local attackers can exploit it by manipulating the COMSPEC environment variable to point to an arbitrary binary before the software performs its version check. This manipulation causes the execFile() function to run the attacker-supplied executable with cmd.exe arguments, leading to arbitrary code execution on Windows systems.

Impact Analysis

The vulnerability allows local attackers to execute arbitrary commands on affected Windows systems. This can lead to unauthorized code execution, potentially compromising system integrity, confidentiality, and availability.
