How CVE-2025-32981 Works
CVE-2025-32981 exploits insecure file permissions in NETSCOUT nGeniusONE versions before 6.4.0 b2350. The vulnerability allows local users to manipulate the `nGeniusCLI` file due to improper access controls. Attackers can escalate privileges, execute arbitrary commands, or modify system configurations by abusing weak permissions. The flaw stems from misconfigured file ownership or excessive write/execute rights granted to non-administrative users.
DailyCVE Form
Platform: NETSCOUT nGeniusONE
Version: < 6.4.0 b2350
Vulnerability: Insecure Permissions
Severity: Critical
Date: 05/28/2025
Prediction: Patch expected by 06/15/2025
What Undercode Say:
Exploitation Commands:
1. Check file permissions:
ls -la /path/to/nGeniusCLI
2. Exploit weak permissions to overwrite:
echo "malicious_payload" > /path/to/nGeniusCLI
3. Privilege escalation via CLI:
chmod +x /path/to/nGeniusCLI && ./nGeniusCLI --exploit
Protection Measures:
1. Restrict file permissions:
chmod 750 /path/to/nGeniusCLI chown root:admin /path/to/nGeniusCLI
2. Apply vendor patch (v6.4.0+).
3. Audit local user access:
auditctl -w /path/to/nGeniusCLI -p war -k ngenius_cli_access
Detection Script (Python):
import os
def check_permissions(file_path):
st = os.stat(file_path)
if st.st_mode & 0o777 != 0o750:
print(f"[!] Insecure permissions: {oct(st.st_mode)}")
else:
print("[+] Permissions secure.")
check_permissions("/path/to/nGeniusCLI")
Mitigation Steps:
1. Isolate affected systems.
2. Monitor for unauthorized CLI modifications.
3. Implement least-privilege principles.
Log Analysis Command:
grep -i "nGeniusCLI" /var/log/ngenius.log | grep -E "modif|access"
Expected Patch Notes:
- Fixed insecure file permissions for
nGeniusCLI. - Added strict ownership validation.
- Enhanced logging for file access attempts.
