OS Command Injection in NexTor IP Changer (CVE-2026-48097)
Summary
OS command injection in NexTor IP Changer (CVE-2026-48097). Successful exploitation can lead to full system takeover. Exploitable via PATH.
Original description
The description as published by the source.
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.
