CVE-2025-3694
📋 TL;DR
This critical SQL injection vulnerability in SourceCodester Web-based Pharmacy Product Management System 1.0 allows remote attackers to execute arbitrary SQL commands via the login_email parameter. Attackers can potentially bypass authentication, access sensitive data, or take control of the database. All deployments of version 1.0 are affected.
💻 Affected Systems
- SourceCodester Web-based Pharmacy Product Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including exfiltration of all sensitive data (patient records, credentials, inventory), authentication bypass leading to admin access, and potential remote code execution on the database server.
Likely Case
Authentication bypass allowing unauthorized access to the system, extraction of user credentials and sensitive pharmacy data, and potential database manipulation.
If Mitigated
Limited impact with proper input validation and WAF rules blocking SQL injection patterns, though risk remains if workarounds are incomplete.
🎯 Exploit Status
Public exploit details available on GitHub. Attack requires no authentication and uses simple SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider implementing workarounds or migrating to alternative software.
🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting login_email parameter
Input Validation Filter
allAdd server-side input validation to sanitize login_email parameter before processing
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from application server only
🔍 How to Verify
Check if Vulnerable:
Test login form with SQL injection payloads in login_email field (e.g., ' OR '1'='1). Monitor for unexpected database responses or authentication bypass.Check Version:
Check application version in admin panel or configuration files. Look for version 1.0 in source code or documentation.Verify Fix Applied:
After implementing workarounds, retest with SQL injection payloads to confirm they are blocked and no longer bypass authentication.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts with SQL-like patterns in email field
- Successful logins from unexpected IP addresses
Network Indicators:
- HTTP POST requests to login endpoint containing SQL keywords in parameters
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND (url_path="/login" OR url_path="/auth") AND (param="login_email" AND value MATCHES "(?i)(union|select|or|and|'|--|#)")
