How the CVE Works:
CVE-2025-3134 is a critical SQL injection vulnerability in Payroll Management System 1.0, specifically in the `/add_overtime.php` file. The flaw arises due to improper sanitization of the `rate` parameter, allowing attackers to inject malicious SQL queries. Remote exploitation is possible, enabling unauthorized database access, data manipulation, or system compromise. The vulnerability leverages insecure input handling, where user-supplied data is directly concatenated into SQL statements without validation or prepared statements. Attackers can exploit this by crafting payloads to bypass authentication, extract sensitive data, or execute arbitrary commands on the database server.
DailyCVE Form:
Platform: Payroll Management System
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 05/14/2025
What Undercode Say:
Exploitation:
- Craft a malicious HTTP request to `/add_overtime.php` with a tampered `rate` parameter:
POST /add_overtime.php HTTP/1.1 Host: target.com rate=1' OR 1=1;--
2. Use automated tools like SQLmap for exploitation:
sqlmap -u "http://target.com/add_overtime.php" --data="rate=1" --risk=3 --level=5
Protection:
- Patch the system by sanitizing inputs and using prepared statements:
$stmt = $conn->prepare("INSERT INTO overtime (rate) VALUES (?)"); $stmt->bind_param("d", $rate);
2. Deploy a WAF to filter SQLi payloads.
3. Restrict database user permissions to minimize impact.
Analytics:
- Attack Vector: Remote (HTTP)
- Impact: Confidentiality/Integrity Loss
- Mitigation Complexity: Low (code fix)
Detection:
grep -r "rate=\$_POST" /var/www/html/
Log Analysis:
SELECT FROM http_logs WHERE url LIKE '%add_overtime.php%' AND request LIKE '%--%';
