CVE-2025-45947

Comprehensive Technical Analysis of CVE-2025-45947

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-45947 Description: An issue in phpgurukul Online Banquet Booking System V1.2 allows an attacker to execute arbitrary code via the /obbs/change-password.php file of the My Account - Change Password component. CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is likely due to the potential for remote code execution (RCE), which can lead to complete system compromise. The severity is further exacerbated by the ease of exploitation and the potential impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Code Execution (RCE): The primary attack vector is the ability to execute arbitrary code. This can be achieved by manipulating input parameters in the change-password.php file.
• Cross-Site Scripting (XSS): If the input is not properly sanitized, an attacker could inject malicious scripts that execute in the context of the user's session.
• SQL Injection: If the input is directly used in SQL queries without proper sanitization, an attacker could manipulate the database.

Exploitation Methods:

• Direct Code Injection: An attacker could inject PHP code directly into the change-password.php file by manipulating the input parameters.
• File Inclusion: If the application allows file inclusion, an attacker could include a malicious file that contains arbitrary code.
• Command Injection: If the application uses system commands based on user input, an attacker could inject malicious commands.

3. Affected Systems and Software Versions

Affected Software:

• phpgurukul Online Banquet Booking System V1.2

Affected Systems:

• Any system running the phpgurukul Online Banquet Booking System V1.2, including web servers, application servers, and any connected databases.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Apply the latest security patches provided by the vendor.
• Input Validation: Ensure all user inputs are properly validated and sanitized.
• Access Controls: Implement strict access controls to limit who can access the change-password.php file.
• Web Application Firewall (WAF): Deploy a WAF to detect and block malicious input patterns.

Long-Term Strategies:

• Code Review: Conduct a thorough code review to identify and fix similar vulnerabilities.
• Security Training: Provide security training for developers to prevent such vulnerabilities in future releases.
• Regular Audits: Perform regular security audits and penetration testing.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-45947 highlights the ongoing challenge of securing web applications against code injection vulnerabilities. This type of vulnerability can have severe consequences, including data breaches, system compromise, and loss of service. It underscores the importance of secure coding practices, regular patching, and continuous monitoring.

6. Technical Details for Security Professionals

Exploit Details:

• Vulnerable Component: /obbs/change-password.php
• Exploit Method: Injecting arbitrary code via input parameters.
• Example Exploit:

  <?php
  // Example of a malicious input that could be used to exploit the vulnerability
  $malicious_input = "'; system('uname -a'); //";
  ?>
  

Detection:

• Log Analysis: Monitor logs for unusual activity, such as unexpected system commands or file modifications.
• Intrusion Detection Systems (IDS): Use IDS to detect and alert on suspicious network traffic.

Remediation:

• Code Fix: Ensure all input parameters are properly sanitized and validated.

  <?php
  // Example of proper input sanitization
  $password = filter_input(INPUT_POST, 'password', FILTER_SANITIZE_STRING);
  ?>
