7.3 HIGH

📋 TL;DR

This critical SQL injection vulnerability in code-projects E-Commerce Website 1.0 allows remote attackers to manipulate database queries via user input fields (firstname, middlename, email, address, contact, username) in user_signup.php. It affects any deployment of this software, potentially enabling unauthorized data access, modification, or deletion.

💻 Affected Systems

Products:
  • code-projects E-Commerce Website
Versions: 1.0
Operating Systems: All, as it's a web application
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability is in user_signup.php and affects all deployments of version 1.0; no specific OS or configuration required.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full database compromise leading to data theft, account takeover, or complete system control via SQL injection escalation.

🟠

Likely Case

Unauthorized access to sensitive user data (e.g., passwords, personal info) and potential website defacement or disruption.

🟢

If Mitigated

Limited impact if input validation and parameterized queries block malicious payloads, though risk persists without patching.

🌐 Internet-Facing: HIGH, as the vulnerability is remotely exploitable via a web-facing file (user_signup.php).
🏢 Internal Only: MEDIUM, if the system is internal-only, but still vulnerable to insider or network-based attacks.

🎯 Exploit Status

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

Exploitation is straightforward via crafted HTTP requests to user_signup.php; public proof-of-concept details are available in GitHub references.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None known

Restart Required: No

Instructions:

No official patch exists; apply workarounds or consider replacing the software.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement strict input validation and use parameterized queries in user_signup.php to prevent SQL injection.

Modify PHP code to use prepared statements, e.g., with PDO or mysqli.

Web Application Firewall (WAF) Rules

all

Deploy a WAF to block SQL injection patterns targeting user_signup.php.

Configure WAF rules to filter malicious SQL payloads in POST/GET requests.

🧯 If You Can't Patch

  • Disable or restrict access to user_signup.php if not essential.
  • Monitor and audit database logs for unusual query patterns.

🔍 How to Verify

Check if Vulnerable:

Test by sending a crafted SQL payload (e.g., ' OR '1'='1) to user_signup.php parameters and observe database errors or unexpected behavior.

Check Version:

Check the software version in documentation or configuration files; no standard command as it's a custom web app.

Verify Fix Applied:

After applying workarounds, retest with SQL payloads to ensure no injection occurs and input is properly sanitized.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL errors in web server logs from user_signup.php requests
  • Multiple failed or anomalous signup attempts with SQL-like strings.

Network Indicators:

  • HTTP POST requests to user_signup.php containing SQL keywords (e.g., UNION, SELECT, DROP).

SIEM Query:

Example: source="web_logs" AND uri="/user_signup.php" AND (payload="' OR" OR payload="UNION" OR payload="SELECT")
