📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise leading to data theft, data destruction, authentication bypass, or remote code execution if database functions allow it.

🟠

Likely Case

Unauthorized data access and manipulation, potentially exposing customer information, order history, and administrative credentials.

🟢

If Mitigated

Limited impact with proper input validation and database permissions restricting damage to non-critical data.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploit details are publicly available on GitHub. The vulnerability requires access to the admin interface, but authentication requirements are unclear from available information.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None known

Restart Required: No

Instructions:

No official patch available. Consider implementing input validation and parameterized queries as described in workarounds, or replace the software entirely.

🔧 Temporary Workarounds

Implement Input Validation

all

Add server-side validation to ensure the bookisbn parameter contains only expected characters (numbers, dashes).

Use Parameterized Queries

all

Rewrite the SQL query in admin_delete.php to use prepared statements with bound parameters instead of string concatenation.

🧯 If You Can't Patch

  • Restrict access to admin_delete.php using web server rules (e.g., .htaccess for Apache) or network firewalls.
  • Implement a Web Application Firewall (WAF) with SQL injection protection rules enabled.

🔍 How to Verify

Check if Vulnerable:

Test the admin_delete.php endpoint with SQL injection payloads in the bookisbn parameter (e.g., ' OR '1'='1). Monitor for unexpected database responses or errors.

Check Version:

Check the software version in the application's configuration files or admin panel. Look for version 1.0 indicators.

Verify Fix Applied:

After implementing fixes, retest with the same payloads to ensure they are properly rejected or sanitized without executing SQL commands.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in web server logs
  • Multiple failed or suspicious requests to admin_delete.php with SQL-like parameters

Network Indicators:

  • HTTP requests to admin_delete.php containing SQL keywords (UNION, SELECT, etc.) in parameters

SIEM Query:

source="web_server_logs" AND uri="*admin_delete.php*" AND (param="*bookisbn*" AND value="*OR*" OR value="*UNION*" OR value="*SELECT*")
