CVE-2025-6961
📋 TL;DR
A critical SQL injection vulnerability exists in Campcodes Employee Management System 1.0, specifically in the /mark.php file's ID parameter. This allows remote attackers to execute arbitrary SQL commands on the database. Any organization using this vulnerable software version is affected.
💻 Affected Systems
- Campcodes Employee Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data manipulation, or full system takeover via SQL injection to RCE chaining.
Likely Case
Unauthorized access to sensitive employee data, credential theft, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and WAF rules blocking SQL injection patterns.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider migrating to alternative software if no fix is provided.
🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the /mark.php file and ID parameter.
Input Validation Filter
allImplement server-side input validation to sanitize the ID parameter, allowing only expected data types (e.g., numeric values).
🧯 If You Can't Patch
- Isolate the system on a segmented network with strict access controls.
- Implement database-level protections: use parameterized queries, least privilege database accounts, and enable SQL injection logging.
🔍 How to Verify
Check if Vulnerable:
Test the /mark.php endpoint with SQL injection payloads in the ID parameter (e.g., ID=1' OR '1'='1). Monitor for database errors or unexpected behavior.Check Version:
Check application files or documentation for version information. Typically found in README files, configuration files, or about pages.Verify Fix Applied:
After implementing workarounds, retest with SQL injection payloads to confirm they are blocked or properly handled without database errors.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts following SQL injection patterns
- Unexpected database queries from web server IP
Network Indicators:
- HTTP requests to /mark.php with SQL keywords in parameters (SELECT, UNION, etc.)
- Abnormal traffic patterns to database port from web server
SIEM Query:
source="web_logs" AND uri_path="/mark.php" AND (param="ID" AND value MATCHES "(?i).*SELECT.*|.*UNION.*|.*OR.*1=1.*")
