CVE-2026-48097: 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 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.
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 use shell=True in command execution with reliance on the PATH environment variable for executable resolution. This improper neutralization of special elements (CWE-78) enables an attacker who can manipulate the execution environment to insert malicious executables (e.g., a fake sudo) earlier in the PATH, leading to execution of attacker-controlled code. The vulnerability is fixed in version 2.0.0.
Potential Impact
An attacker with the ability to control the execution environment can execute arbitrary code with the privileges of the NexTor IP Changer process. This can lead to full compromise of the affected system, including confidentiality, integrity, and availability impacts as indicated by the CVSS score of 7.8 (high severity).
Mitigation Recommendations
Upgrade to NexTor IP Changer version 2.0.0 or later, where this vulnerability has been fixed. No other official remediation or temporary fixes are documented. Until upgrading, avoid running the tool in environments where the PATH can be manipulated by untrusted users.
