CVE-2017-1000444
📋 TL;DR
CVE-2017-1000444 is a critical SQL injection vulnerability in Eleix Openhacker's account registration and login components. Attackers can exploit this to execute arbitrary SQL commands, potentially leading to information disclosure and remote code execution. All users running vulnerable versions of Openhacker are affected.
💻 Affected Systems
- Eleix Openhacker
📦 What is this software?
Openhacker by Openhacker Project
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via remote code execution, allowing attackers to execute arbitrary commands, steal sensitive data, and pivot to other systems.
Likely Case
Database information disclosure including user credentials, followed by potential privilege escalation and limited code execution.
If Mitigated
SQL injection attempts are blocked by input validation and parameterized queries, preventing exploitation.
🎯 Exploit Status
SQL injection in authentication endpoints is well-understood and easily weaponized. Public references demonstrate the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after commit 9da5c237ba5e2311f01edc83389bc5aaf0a9885c
Vendor Advisory: https://github.com/Eleix/openhacker/commit/9da5c237ba5e2311f01edc83389bc5aaf0a9885c
Restart Required: Yes
Instructions:
1. Update Openhacker to a version after commit 9da5c237ba5e2311f01edc83389bc5aaf0a9885c. 2. Restart the Openhacker service. 3. Verify the fix by testing authentication endpoints.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
Input Validation Filter
allImplement input validation to reject SQL special characters in authentication fields.
🧯 If You Can't Patch
- Isolate the Openhacker instance behind a firewall with strict access controls.
- Implement network segmentation to limit potential lateral movement if compromised.
🔍 How to Verify
Check if Vulnerable:
Check if running Openhacker version 0.1.47. Review authentication endpoint code for SQL injection vulnerabilities.Check Version:
Check Openhacker configuration files or package manager for version information.Verify Fix Applied:
Verify the code includes the fix from commit 9da5c237ba5e2311f01edc83389bc5aaf0a9885c. Test authentication endpoints with SQL injection payloads.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts with SQL syntax
- Unexpected database queries from authentication endpoints
Network Indicators:
- HTTP requests to login/registration endpoints containing SQL keywords
- Unusual traffic patterns to authentication services
SIEM Query:
