CVE-2025-70893
📋 TL;DR
A time-based blind SQL injection vulnerability in PHPGurukul Cyber Cafe Management System v1.0 allows authenticated attackers to execute arbitrary SQL commands via the adminname parameter in adminprofile.php. This can lead to data theft, manipulation, or complete system compromise. Only systems running this specific software version are affected.
💻 Affected Systems
- PHPGurukul Cyber Cafe Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including extraction of all user credentials, financial data, and system takeover through privilege escalation or remote code execution.
Likely Case
Data exfiltration of sensitive information including admin credentials, customer data, and financial records from the cyber cafe database.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing successful injection attempts.
🎯 Exploit Status
Exploitation requires authenticated admin access and uses time-based blind SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/cyber-cafe-management-system-using-php-mysql/
Restart Required: No
Instructions:
No official patch available. Implement input validation and parameterized queries manually.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize adminname parameter
Edit adminprofile.php to add: $adminname = mysqli_real_escape_string($conn, $_POST['adminname']);
WAF Rule Implementation
linuxAdd web application firewall rules to block SQL injection patterns
ModSecurity rule: SecRule ARGS:adminname "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Implement network segmentation to isolate the vulnerable system from sensitive databases
- Enable detailed logging and monitoring for SQL injection attempts on adminprofile.php endpoint
🔍 How to Verify
Check if Vulnerable:
Test adminprofile.php endpoint with time-based SQL injection payloads like: adminname=admin' AND SLEEP(5)--Check Version:
Check PHPGurukul Cyber Cafe Management System version in admin panel or readme filesVerify Fix Applied:
Test with same payloads after implementing fixes - should return immediate response without delay📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts followed by adminprofile.php requests with SQL keywords
- Unusual time delays in adminprofile.php responses
Network Indicators:
- HTTP POST requests to adminprofile.php containing SQL keywords like UNION, SELECT, SLEEP, BENCHMARK
SIEM Query:
source="web_logs" AND uri="/adminprofile.php" AND (request_body CONTAINS "SLEEP" OR request_body CONTAINS "BENCHMARK" OR request_body CONTAINS "UNION SELECT")
