CVE-2025-13555: Critical SQL Injection Threatens Campcodes School File Management System 1.0

Overview

CVE-2025-13555 is a high-severity SQL injection vulnerability discovered in Campcodes School File Management System version 1.0. This vulnerability allows a remote attacker to execute arbitrary SQL commands by manipulating the stud_no parameter within the /index.php file, specifically related to the Login component. The exploit is publicly available, increasing the urgency for administrators to apply the necessary mitigation steps.

Technical Details

The vulnerability exists because the application fails to properly sanitize user-supplied input passed to the stud_no parameter during the login process. An attacker can craft a malicious SQL query within this parameter, potentially allowing them to bypass authentication, extract sensitive data, modify database records, or even compromise the entire system. The affected endpoint is /index.php within the Login component of the application. The attack is performed remotely without requiring prior authentication. The vulnerability resides in the lack of proper input validation and sanitization of the stud_no parameter.

CVSS Analysis

• CVSS Score: 7.3 (HIGH)
• Vector String: (Analysis not possible without complete vector string, estimate based on CVSS v3.x: AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) – Example Only
• This score indicates a significant risk due to the ease of exploitation (no authentication required, low attack complexity) and the potential impact (data compromise, system modification).

Possible Impact

Successful exploitation of CVE-2025-13555 can have severe consequences:

• Data Breach: Unauthorized access to sensitive student, faculty, and administrative data.
• Account Takeover: Attackers can gain control of user accounts, including those with administrative privileges.
• System Compromise: Full control of the database server, potentially leading to the compromise of the entire system.
• Denial of Service: Attackers might be able to disrupt the system’s availability for legitimate users.
• Data Manipulation: Alteration or deletion of critical data, leading to inaccuracies and operational disruptions.

Mitigation and Patch Steps

1. Apply the Patch: Check the Campcodes website for an official patch or update that addresses this vulnerability. If a patch is available, apply it immediately following the vendor’s instructions.
2. Input Validation: Implement robust input validation and sanitization on the stud_no parameter. Ensure that all user input is properly validated against expected patterns and that any potentially malicious characters are escaped or removed.
3. Parameterized Queries (Prepared Statements): Utilize parameterized queries (also known as prepared statements) when interacting with the database. This prevents SQL injection by treating user input as data rather than executable code.
4. Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious requests attempting to exploit this vulnerability. Configure the WAF with rules that specifically target SQL injection attacks.
5. Least Privilege Principle: Ensure that the database user account used by the application has only the necessary privileges. Avoid granting excessive permissions that could be exploited by an attacker.
6. Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the application and its infrastructure.
