How the CVE Works
The CVE-2025-XXXX vulnerability in AWorld OS stems from improper input sanitization in the `subprocess.run` and `subprocess.Popen` functions within shell_tool.py. Attackers can inject malicious OS commands through crafted inputs, leading to arbitrary command execution. Since the application lacks versioning, all instances up to commit `8c257626e648d98d793dd9a1a950c2af4dd84c4e` are affected. Remote exploitation is possible but requires high complexity due to indirect attack vectors.
DailyCVE Form
Platform: AWorld OS
Version: <= 8c257626e648
Vulnerability: OS Command Injection
Severity: Critical
Date: Apr 29, 2025
What Undercode Say:
Exploitation Analysis
1. Exploit Payload Example:
import subprocess malicious_input = "malicious_command; whoami" subprocess.run(malicious_input, shell=True) Vulnerable call
2. Remote Attack Vector:
curl -X POST "http://target/endpoint?cmd=malicious_command%3B%20cat%20/etc/passwd"
Protection Measures
1. Input Sanitization:
import shlex safe_input = shlex.quote(user_input) subprocess.run(["ls", safe_input], shell=False) Safe usage
2. Disable Shell Execution:
subprocess.run(command_list, shell=False) Prevents injection
Detection Commands
1. Check Vulnerable Calls:
grep -r "subprocess.run(.shell=True" /path/to/AWorld
2. Log Analysis:
journalctl -u aworld | grep "sh:"
Patch Advisory
- Replace `shell=True` with explicit command arrays.
- Implement strict input validation via regex or allowlists.
- Update to a patched commit post
8c257626e648.
Mitigation Script
def safe_command_exec(cmd):
if not all(c.isalnum() for c in cmd.split()):
raise ValueError("Invalid characters in command")
subprocess.run(cmd.split(), shell=False)
