CVE-2024-9032

6.3 MEDIUM

📋 TL;DR

A critical path traversal vulnerability in SourceCodester Simple Forum-Discussion System 1.0 allows remote attackers to access arbitrary files on the server by manipulating the 'page' parameter in /index.php. This affects all installations of version 1.0 that are exposed to untrusted networks. Attackers can potentially read sensitive system files without authentication.

💻 Affected Systems

Products:
  • SourceCodester Simple Forum-Discussion System
Versions: 1.0
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: All default installations are vulnerable. The vulnerability exists in the core index.php file.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete server compromise through reading sensitive configuration files (like database credentials), followed by data exfiltration or further system exploitation.

🟠

Likely Case

Unauthorized access to sensitive files containing configuration data, user information, or system files, potentially leading to credential theft or information disclosure.

🟢

If Mitigated

Limited impact if proper file permissions and web server configurations restrict access to sensitive directories and files.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploit details are publicly available. Attack requires simple HTTP requests with manipulated parameters.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://www.sourcecodester.com/

Restart Required: No

Instructions:

No official patch available. Consider upgrading to a newer version if available, or implement workarounds.

🔧 Temporary Workarounds

Input Validation Filter

all

Add input validation to sanitize the 'page' parameter in index.php to prevent directory traversal sequences.

Edit index.php and add: if (strpos($_GET['page'], '..') !== false) { die('Invalid request'); }

Web Server Restriction

all

Configure web server to restrict access to parent directories and sensitive file paths.

For Apache: <LocationMatch "\\.\\."> Require all denied </LocationMatch>
For Nginx: location ~ \\.\\. { deny all; }

🧯 If You Can't Patch

  • Remove the system from internet-facing networks and restrict access to trusted internal users only.
  • Implement a web application firewall (WAF) with rules to block path traversal patterns in requests.

🔍 How to Verify

Check if Vulnerable:

Test by accessing /index.php?page=../../../../etc/passwd (or similar system file) and check if file contents are returned.

Check Version:

Check the software version in admin panel or readme files; version 1.0 is vulnerable.

Verify Fix Applied:

After applying workarounds, retest the same traversal attempts; they should be blocked or return error messages.

📡 Detection & Monitoring

Log Indicators:

  • HTTP requests to index.php with 'page' parameter containing '..' sequences
  • Access to unexpected file paths in web server logs

Network Indicators:

  • HTTP GET requests with traversal patterns in query strings
  • Unusual file access patterns from web clients

SIEM Query:

source="web_server_logs" AND uri="*index.php*" AND query="*..*"
