CVE-2024-35469
📋 TL;DR
This SQL injection vulnerability in SourceCodester Human Resource Management System 1.0 allows attackers to execute arbitrary SQL commands via the password parameter in the /hrm/user/ endpoint. Attackers can potentially access, modify, or delete database contents, including sensitive HR data. Organizations using this specific version of the software are affected.
💻 Affected Systems
- SourceCodester Human Resource Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized access to sensitive HR data (employee records, salaries, personal information), authentication bypass, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permissions restricting damage to non-critical data.
🎯 Exploit Status
Exploit code is publicly available on GitHub. The vulnerability is in a login-related parameter, making exploitation straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch exists. Consider the workarounds below or discontinue use of the software.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation to reject SQL special characters in the password parameter.
Web Application Firewall (WAF) Rule
allDeploy a WAF rule to block SQL injection patterns targeting the /hrm/user/ endpoint.
🧯 If You Can't Patch
- Isolate the HRM system on a separate network segment with strict access controls.
- Implement network-level filtering to restrict access to the /hrm/user/ endpoint to trusted IPs only.
🔍 How to Verify
Check if Vulnerable:
Test the /hrm/user/ endpoint with SQL injection payloads in the password parameter (e.g., ' OR '1'='1). Monitor for unexpected database errors or successful authentication bypass.Check Version:
Check the software version in the admin panel or by reviewing the source code files for version identifiers.Verify Fix Applied:
After applying workarounds, retest with the same payloads to ensure they are blocked or sanitized without allowing SQL execution.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax errors in application logs
- Multiple failed login attempts with SQL-like strings in the password field
- Unexpected database query patterns from the application server
Network Indicators:
- HTTP requests to /hrm/user/ containing SQL keywords (e.g., UNION, SELECT, OR) in POST parameters
SIEM Query:
source="web_server_logs" AND uri_path="/hrm/user/" AND (post_data LIKE "%OR%" OR post_data LIKE "%UNION%" OR post_data LIKE "%SELECT%")🔗 References
