Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

How this class of weakness works · CWE-78

User input reaches a shell or system command without being fully separated from the command itself, so an attacker can append their own instructions. Because these run with the application's privileges, it often means full control of the host. The lasting fix is to avoid the shell entirely — call APIs directly and pass arguments as data, never as concatenated strings.

Recommended fix High confidence

Version 2.0.0

  1. 1. Identify the current installed version of NexTor IP Changer by running the version command or checking the binary.
  2. 2. If the current version is prior to 2.0.0, plan for upgrade to version 2.0.0.
  3. 3. Before upgrading, backup any existing configuration files or data used by NexTor IP Changer.
  4. 4. Obtain version 2.0.0 of NexTor IP Changer from the official source.
  5. 5. Install version 2.0.0, replacing the previous installation.
  6. 6. Restore any backed-up configuration files to the new installation.
  7. 7. Verify the new version is 2.0.0 or later by checking the version.
  8. 8. Test that the tool functions correctly with the new version.
