Command Injection in NexTor IP Changer

Publication date: 2026-08-07

Last updated on: 2026-08-07

Assigner: GitHub, Inc.

Description
NexTor IP Changer is a command-line tool that leverages the Tor network to periodically rotate a user's IP address. Versions prior to 2.0.0 have a command execution vulnerability due to unsafe use of `shell=True` with commands that rely on executable resolution through the `PATH` environment variable. An attacker controlling the execution environment can place malicious executables such as sudo earlier in the `PATH`, resulting in execution of attacker-controlled code. Version 2.0.0 fixes the issue.

Executive Summary

NexTor IP Changer is a tool that uses the Tor network to change a user's IP address periodically. Versions before 2.0.0 have a command execution vulnerability because they use unsafe shell=True with commands that rely on the PATH environment variable. An attacker can manipulate the PATH to place malicious executables earlier, causing the system to run attacker-controlled code instead of the intended commands.

Detection Guidance

Check if NexTor IP Changer version is below 2.0.0 by running: nex-tor-ip-changer --version. Inspect PATH environment variable for suspicious entries using: echo $PATH. Look for executables like sudo in PATH directories.

Impact Analysis

This vulnerability allows local attackers with low privileges to execute arbitrary commands on your system. This could lead to unauthorized access, data theft, system damage, or further compromise of your machine. The impact includes high risks to confidentiality, integrity, and availability of your system.

Mitigation Strategies

Upgrade NexTor IP Changer to version 2.0.0 or later. Avoid using shell=True in scripts. Use absolute paths for system commands. Remove untrusted entries from PATH.
