CVE-2023-34751

9.8 CRITICAL

📋 TL;DR

This SQL injection vulnerability in bloofox v0.5.2.1 allows attackers to execute arbitrary SQL commands via the gid parameter in the admin interface. This affects all systems running the vulnerable version of bloofox, potentially enabling unauthorized data access, modification, or deletion.

💻 Affected Systems

Products:
  • bloofox
Versions: v0.5.2.1
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: Requires access to admin interface, but authentication may be bypassed through other means.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including data exfiltration, privilege escalation to admin, and potential remote code execution if database functions allow it.

🟠

Likely Case

Unauthorized access to user data, modification of user permissions, and potential administrative control of the bloofox application.

🟢

If Mitigated

Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

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

SQL injection via gid parameter is well-documented and easy to exploit with standard SQLi techniques.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None available

Restart Required: No

Instructions:

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

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement proper input validation and parameterized queries for the gid parameter

Modify admin/index.php to use prepared statements for SQL queries involving gid parameter

Web Application Firewall Rules

all

Block SQL injection patterns in the gid parameter

Add WAF rule: deny requests containing SQL keywords in gid parameter

🧯 If You Can't Patch

  • Restrict access to admin interface using IP whitelisting or VPN
  • Implement database user with minimal necessary permissions (read-only where possible)

🔍 How to Verify

Check if Vulnerable:

Test the gid parameter with SQL injection payloads like ' OR '1'='1 at admin/index.php?mode=user&page=groups&action=edit

Check Version:

Check bloofox version in configuration files or admin interface

Verify Fix Applied:

Test with same SQL injection payloads and verify they no longer execute

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed login attempts followed by admin access
  • Requests with SQL keywords in gid parameter

Network Indicators:

  • Unusual database connections from web server
  • Large data transfers from database

SIEM Query:

source=web_logs AND (gid CONTAINS "UNION" OR gid CONTAINS "SELECT" OR gid CONTAINS "OR '1'='1")
