CVE-2026-3752
📋 TL;DR
This vulnerability allows remote attackers to execute SQL injection attacks via the Date parameter in the /daily-task-report.php file of SourceCodester Employee Task Management System. It affects all users running versions up to 1.0, potentially leading to unauthorized database access or manipulation. The exploit is publicly available, increasing the risk of widespread attacks.
💻 Affected Systems
- SourceCodester Employee Task Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could gain full control of the database, leading to data theft, deletion, or system compromise, including potential remote code execution if database privileges allow.
Likely Case
Unauthorized access to sensitive employee task data, such as personal information or task details, with possible data exfiltration or tampering.
If Mitigated
If proper input validation and SQL parameterization are in place, the impact is minimized to failed attack attempts with no data compromise.
🎯 Exploit Status
The exploit is simple to execute using publicly available scripts, requiring minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch is available. Monitor the vendor's website for updates and apply any future patches immediately. In the meantime, implement workarounds such as input validation or WAF rules.
🔧 Temporary Workarounds
Implement Input Validation and Sanitization
allAdd server-side validation to sanitize the Date parameter, rejecting malicious SQL characters.
Modify /daily-task-report.php to use prepared statements, e.g., in PHP: $stmt = $conn->prepare('SELECT * FROM tasks WHERE date = ?'); $stmt->bind_param('s', $date);
Deploy Web Application Firewall (WAF)
linuxConfigure WAF rules to block SQL injection attempts targeting the /daily-task-report.php endpoint.
Add custom rule to block requests with SQL keywords in the Date parameter, e.g., using ModSecurity: SecRule ARGS:Date "(?i:(union|select|insert|delete|update|drop|--|#|\/\*|\*\/|xp_))" "deny,status:403,id:1001"
🧯 If You Can't Patch
- Restrict network access to the application by placing it behind a firewall or VPN, limiting exposure to trusted users only.
- Monitor and audit database logs for unusual SQL queries or access patterns, and implement intrusion detection systems to alert on exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Test by sending a crafted request to /daily-task-report.php with a malicious Date parameter (e.g., Date=1' OR '1'='1) and check for SQL errors or unexpected responses in the application output.Check Version:
Check the application's version in its admin panel or configuration files; for SourceCodester systems, look in files like version.txt or database settings.Verify Fix Applied:
After applying workarounds, retest with the same malicious input; the application should reject the request or return an error without executing SQL, and logs should show blocked attempts.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs, such as UNION SELECT statements; HTTP logs showing requests to /daily-task-report.php with suspicious Date parameters containing SQL keywords.
Network Indicators:
- Incoming traffic to the web server on port 80/443 with payloads like ' OR '1'='1 in the URL parameters; spikes in error responses from the application.
SIEM Query:
source="web_logs" AND url="/daily-task-report.php" AND (param="Date" AND value MATCHES "(?i:union|select|insert|delete|update|drop|--|#|\/\*|\*\/)")
