CVE-2010-5333
📋 TL;DR
This is a critical buffer overflow vulnerability in Integard web server that allows remote attackers to execute arbitrary code by sending a specially crafted long password in login requests. It affects Integard Pro and Home editions running vulnerable versions. Attackers can exploit this without authentication to gain complete control of affected systems.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with administrative privileges, allowing attackers to install malware, steal data, pivot to other systems, or create persistent backdoors.
Likely Case
Remote code execution leading to ransomware deployment, data exfiltration, or botnet recruitment of vulnerable systems.
If Mitigated
Limited impact with proper network segmentation and intrusion prevention systems blocking exploit attempts.
🎯 Exploit Status
Metasploit module available, multiple public exploit scripts exist, making exploitation trivial for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Pro 2.0.0.9037+, 2.2.0.9037+; Home 2.0.0.9037+, 2.2.0.9037+
Vendor Advisory: Not available - vendor appears defunct
Restart Required: Yes
Instructions:
1. Download latest version from official Integard website. 2. Backup configuration. 3. Uninstall old version. 4. Install patched version. 5. Restart system. 6. Restore configuration.
🔧 Temporary Workarounds
Network Access Control
windowsRestrict access to Integard web interface to trusted IP addresses only
Windows Firewall: netsh advfirewall firewall add rule name="Block Integard External" dir=in action=block protocol=TCP localport=80,443 remoteip=any
netsh advfirewall firewall add rule name="Allow Integard Internal" dir=in action=allow protocol=TCP localport=80,443 remoteip=192.168.1.0/24
Web Application Firewall
allDeploy WAF to block buffer overflow attempts in HTTP POST parameters
ModSecurity rule: SecRule ARGS "@rx ^.{1000,}" "id:1001,phase:2,deny,msg:'Possible buffer overflow attempt'"
Add to httpd.conf: SecRuleEngine On
🧯 If You Can't Patch
- Immediately isolate affected systems from internet and restrict network access to administrative interfaces only
- Implement application whitelisting to prevent execution of unauthorized code even if exploit succeeds
🔍 How to Verify
Check if Vulnerable:
Check Integard version in web interface or program directory. If version is below patched versions, system is vulnerable. Test with proof-of-concept exploit in controlled environment.
Check Version:
Check Integard web interface or registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Integard\Version
Verify Fix Applied:
Verify version is 2.0.0.9037 or higher for major version 2.0, or 2.2.0.9037 or higher for major version 2.2. Attempt exploitation with known payloads should fail.
📡 Detection & Monitoring
Log Indicators:
- Unusually long password fields in HTTP POST requests (>1000 characters)
- Multiple failed login attempts with varying password lengths
- Web server crashes or unexpected restarts
Network Indicators:
- HTTP POST requests to /login or administrative endpoints with abnormally long parameters
- Shellcode patterns in network traffic following login attempts
SIEM Query:
source="web_server" AND (url_path="/login" OR url_path="*/admin*") AND http_method="POST" AND (form_data_length>1000 OR contains(form_data,"\x90\x90\x90") OR contains(form_data,"\xcc"))
