CVE-2026-48097 — PATH Injection Leading to Arbitrary Command Execution in NexTOR IP Changer

High-severity PATH injection vulnerability in NexTOR IP Changer where unsafe executable resolution through the PATH environment variable could allow arbitrary command execution.

Overview

CVE-2026-48097 is a high-severity vulnerability affecting NexTOR IP Changer. The issue originated from unsafe command execution practices that relied on executable resolution through the system PATH environment variable.

Under specific conditions, an attacker capable of influencing the execution environment could cause the application to invoke attacker-controlled binaries instead of legitimate system utilities.

CVE-2026-48097

Technical Description

The affected version executed certain system commands using mechanisms that relied on locating executables through the current PATH environment. If an attacker controlled or manipulated this environment, malicious executables placed earlier in the search path could be executed in place of trusted system binaries.

Potential Impact

Successful exploitation could potentially allow:

  • Arbitrary command execution.
  • Execution of attacker-controlled binaries.
  • Abuse of trusted application functionality.
  • Potential privilege escalation depending on deployment configuration.
  • Compromise of local system integrity and availability.

The practical impact depends on the privileges available to the affected process.

Affected and Fixed Versions

Affected1.0.0-1
Fixedv2.0.0

Remediation

The vulnerability was fully addressed in NexTOR IP Changer v2.0.0 through:

  • Secure Command Execution: Updated to invoke trusted system components using explicit execution paths, eliminating reliance on shell resolution.
  • PATH Resolution Hardening: Internal handling of executable resolution reviewed to prevent unintended reliance on user-controlled environment variables.
  • Environment Validation: Additional safeguards to validate the execution environment before privileged operations.
  • Process Isolation Improvements: Execution subsystem updated to reduce trust in inherited runtime state.
  • Defense-in-Depth: Removal of shell-dependent execution patterns, improved validation around privileged operations, reduction of the overall local attack surface.
  • Post-remediation codebase security audit and verification.
