CVE-2024-28556
📋 TL;DR
This CVE describes a critical SQL injection vulnerability in the Sourcecodester PHP Task Management System v1.0. Attackers can exploit this via crafted payloads to admin-manage-user.php to execute arbitrary SQL commands, potentially leading to remote code execution, privilege escalation, and data theft. All deployments of this specific software version are affected.
💻 Affected Systems
- Sourcecodester PHP Task Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise: attackers gain administrative access, execute arbitrary code on the server, steal all database contents (including credentials), and potentially pivot to other systems.
Likely Case
Database compromise leading to sensitive information disclosure (user credentials, task data), privilege escalation to admin, and potential website defacement.
If Mitigated
Attack attempts are blocked at the web application firewall level, preventing exploitation but potentially causing service disruption from attack traffic.
🎯 Exploit Status
Exploitation requires access to the admin-manage-user.php endpoint, which typically requires authentication. However, if default credentials are unchanged or other vulnerabilities exist, this could be chained for unauthenticated access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check Sourcecodester website for security updates. 2. If no patch exists, implement workarounds immediately. 3. Consider replacing with alternative software.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify admin-manage-user.php to use prepared statements with parameterized queries instead of concatenating user input into SQL.
Replace vulnerable SQL queries with PDO or mysqli prepared statements
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection rules to block malicious payloads before they reach the application.
Configure WAF rules to block SQL injection patterns
🧯 If You Can't Patch
- Isolate the system on a segmented network with strict access controls
- Implement network-based intrusion detection to monitor for SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test the admin-manage-user.php endpoint with SQL injection payloads (e.g., single quote) and observe if database errors are returned.Check Version:
Check the software version in the application interface or configuration filesVerify Fix Applied:
After implementing parameterized queries, retest with SQL injection payloads and verify no database errors or unexpected behavior occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax errors in web server logs
- Multiple failed login attempts followed by SQL-like payloads to admin-manage-user.php
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) sent to admin-manage-user.php
SIEM Query:
source="web_server" AND (uri="*admin-manage-user.php*" AND (message="*SQL*" OR message="*syntax*"))
