CVE-2010-5333

9.8 CRITICAL

📋 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.

💻 Affected Systems

Products:
  • Integard Pro
  • Integard Home
Versions: Pro: before 2.0.0.9037, 2.2.x before 2.2.0.9037; Home: before 2.0.0.9037, 2.2.x before 2.2.0.9037
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: The web server component is vulnerable in default configurations. Both SEH-overwrite and EIP-overwrite exploitation methods exist.

📦 What is this software?

⚠️ 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.

🌐 Internet-Facing: HIGH - Exploit is unauthenticated and weaponized, making internet-facing instances prime targets for automated attacks.
🏢 Internal Only: HIGH - Even internally, this provides easy lateral movement opportunity for attackers who gain initial access.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: CONFIRMED
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

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

windows

Restrict 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

all

Deploy 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"))
