CVE-2024-53604

9.8 CRITICAL

📋 TL;DR

A SQL injection vulnerability in PHPGurukul COVID 19 Testing Management System v1.0 allows remote attackers to execute arbitrary SQL commands via the mobnumber parameter in the check_availability.php endpoint. This can lead to database compromise, data theft, or complete system takeover. Organizations using this specific version of the COVID testing management system are affected.

💻 Affected Systems

Products:
  • PHPGurukul COVID 19 Testing Management System
Versions: v1.0
Operating Systems: Any OS running PHP and MySQL/MariaDB
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the default installation and requires no special configuration to be exploitable.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise leading to data exfiltration, privilege escalation to administrative access, and potential remote code execution on the underlying server.

🟠

Likely Case

Unauthorized access to sensitive COVID testing data including patient records, test results, and personal information, potentially leading to data breach and regulatory violations.

🟢

If Mitigated

Limited impact with proper input validation and parameterized queries preventing SQL injection, though system may still be vulnerable to other attacks.

🌐 Internet-Facing: HIGH - The vulnerable endpoint is accessible via HTTP POST requests, making it directly exploitable from the internet without authentication.
🏢 Internal Only: HIGH - Even if not internet-facing, internal attackers or compromised systems could exploit this vulnerability to gain unauthorized database access.

🎯 Exploit Status

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

The vulnerability requires no authentication and can be exploited with basic SQL injection techniques. Public proof-of-concept documentation exists.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Not available

Restart Required: No

Instructions:

No official patch available. Consider migrating to alternative COVID testing management systems or implementing custom security fixes.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement strict input validation for the mobnumber parameter to only accept valid phone number formats

Modify check_availability.php to validate mobnumber parameter using regex: /^[0-9]{10}$/

Parameterized Queries Implementation

all

Replace direct SQL string concatenation with prepared statements using PDO or mysqli

Replace vulnerable SQL code with prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE mobnumber = ?'); $stmt->bind_param('s', $mobnumber);

🧯 If You Can't Patch

  • Implement a web application firewall (WAF) with SQL injection protection rules
  • Restrict network access to the vulnerable endpoint using firewall rules or authentication

🔍 How to Verify

Check if Vulnerable:

Send a POST request to /covid-tms/check_availability.php with mobnumber parameter containing SQL injection payload like ' OR '1'='1

Check Version:

Check system documentation or about page for version information, or examine PHP file headers

Verify Fix Applied:

Test with SQL injection payloads and verify they are rejected or sanitized without affecting database queries

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in web server logs
  • Multiple failed login attempts or unusual parameter values in access logs

Network Indicators:

  • HTTP POST requests to /covid-tms/check_availability.php with SQL keywords in parameters
  • Unusual database query patterns from web server IP

SIEM Query:

source="web_server" AND (url_path="/covid-tms/check_availability.php" AND (param="mobnumber" AND value CONTAINS "' OR" OR value CONTAINS "UNION" OR value CONTAINS "SELECT"))
