CVE-2026-48098: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in 0x5t4l1n NexTOR_IP_CHANGER
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 execute privileged system commands using `sudo` and `shell=True` directly inside application logic. In environments where passwordless sudo (`NOPASSWD`) is enabled, privileged commands may execute silently without explicit user confirmation. Version 2.0.0 fixes the issue.
AI Analysis
Technical Summary
NexTOR_IP_CHANGER is a command-line tool that rotates a user's IP address via the Tor network. Versions before 2.0.0 execute privileged system commands using sudo with shell=True directly in the application logic. When passwordless sudo (NOPASSWD) is enabled, these commands can run silently without user confirmation, leading to an OS command injection vulnerability (CWE-78) and improper access control (CWE-250). The vulnerability is addressed in version 2.0.0.
Potential Impact
An attacker with local privileges can exploit this vulnerability to execute arbitrary privileged system commands without user interaction if passwordless sudo is configured. This can lead to full system compromise, including confidentiality, integrity, and availability impacts as reflected by the CVSS score of 7.3 (high).
Mitigation Recommendations
Upgrade to NexTOR_IP_CHANGER version 2.0.0 or later, which fixes the vulnerability by removing the unsafe use of sudo and shell=True. Until upgraded, avoid running the tool in environments where passwordless sudo is enabled or restrict sudo permissions to prevent silent privileged command execution.
