CVE-2024-7933
📋 TL;DR
This critical SQL injection vulnerability in itsourcecode Project Expense Monitoring System 1.0 allows remote attackers to execute arbitrary SQL commands via the 'user' parameter in login1.php. This can lead to authentication bypass, data theft, or complete system compromise. All deployments of version 1.0 with the vulnerable login component are affected.
💻 Affected Systems
- itsourcecode Project Expense Monitoring System
📦 What is this software?
Project Expense Monitoring System by Project Expense Monitoring System Project
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover: attacker gains administrative access, exfiltrates all database contents (including sensitive user data), and potentially executes arbitrary code on the underlying server.
Likely Case
Authentication bypass leading to unauthorized access to the expense monitoring system, followed by data theft or manipulation of financial records.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or failed login attempts visible.
🎯 Exploit Status
Exploit details are publicly available on GitHub. SQL injection via user parameter requires minimal technical skill to execute.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Consider replacing with alternative software or implementing custom fixes.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify login1.php to use prepared statements with parameterized queries instead of concatenating user input into SQL.
Replace vulnerable SQL code with: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ?'); $stmt->bind_param('s', $user); $stmt->execute();
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns in login requests.
Configure WAF to block requests containing SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, OR 1=1 in the user parameter.
🧯 If You Can't Patch
- Isolate the system on a segmented network with strict access controls
- Implement network-level monitoring for SQL injection patterns in HTTP requests
🔍 How to Verify
Check if Vulnerable:
Test login1.php with SQL injection payloads in the user parameter (e.g., ' OR '1'='1). If login succeeds without valid credentials, system is vulnerable.Check Version:
Check the software version in the application interface or configuration files. Look for version 1.0 in source code or documentation.Verify Fix Applied:
After applying fixes, repeat SQL injection tests. Successful login should only occur with valid credentials, and SQL errors should not be returned.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts with SQL-like patterns in username field
- Successful logins from unexpected IP addresses
Network Indicators:
- HTTP POST requests to login1.php containing SQL keywords in parameters
- Unusual database query patterns from the application server
SIEM Query:
source="web_logs" AND uri="/login1.php" AND (user="*OR*" OR user="*UNION*" OR user="*SELECT*")
