CVE-2024-25239
📋 TL;DR
This CVE describes a critical SQL injection vulnerability in Sourcecodester Employee Management System v1.0, allowing attackers to execute arbitrary SQL commands via a crafted POST request to the login page. It affects all deployments of this specific software version, potentially leading to unauthorized data access or system compromise.
💻 Affected Systems
- Sourcecodester Employee Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise, including theft of sensitive employee data, authentication bypass, remote code execution, or full system takeover.
Likely Case
Unauthorized access to the database, data exfiltration, privilege escalation, or manipulation of employee records.
If Mitigated
Limited impact if proper input validation, parameterized queries, and network segmentation are in place, though risk remains high without patching.
🎯 Exploit Status
Exploitation is straightforward via crafted HTTP POST requests, as detailed in public references, with no authentication required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch is known; consider upgrading to a newer version if available, or apply workarounds and mitigations.
🔧 Temporary Workarounds
Implement Input Validation and Sanitization
allAdd server-side validation to sanitize user inputs in the login.php script, rejecting malicious SQL characters.
Edit /emloyee_akpoly/Account/login.php to include input filtering, e.g., using mysqli_real_escape_string() or prepared statements.
Use Web Application Firewall (WAF)
allDeploy a WAF to block SQL injection attempts targeting the vulnerable endpoint.
Configure WAF rules to detect and block patterns like ' OR '1'='1 in POST requests to /emloyee_akpoly/Account/login.php.
🧯 If You Can't Patch
- Isolate the system from the internet and restrict access to trusted networks only.
- Monitor and log all access to the login.php endpoint for suspicious activity.
🔍 How to Verify
Check if Vulnerable:
Send a crafted POST request to /emloyee_akpoly/Account/login.php with SQL injection payloads (e.g., ' OR '1'='1) and check for error responses or unexpected behavior.Check Version:
Check the software version in the system's documentation or configuration files; no standard command is provided by the vendor.Verify Fix Applied:
After applying workarounds, test with the same payloads to ensure they are blocked or sanitized without allowing SQL execution.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs, multiple failed login attempts with SQL-like strings, or unexpected database queries from the login endpoint.
Network Indicators:
- HTTP POST requests to /emloyee_akpoly/Account/login.php containing SQL keywords (e.g., UNION, SELECT, OR) in parameters.
SIEM Query:
Example: source="web_logs" AND url="/emloyee_akpoly/Account/login.php" AND (payload CONTAINS "' OR" OR payload CONTAINS "UNION")
