CVE-2025-7634

Comprehensive Technical Analysis of CVE-2025-7634

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-7634 CVSS Score: 9.8

The vulnerability in the WP Travel Engine – Tour Booking Plugin – Tour Operator Software for WordPress allows for Local File Inclusion (LFI) via the mode parameter. This vulnerability is critical due to its high CVSS score of 9.8, indicating a severe risk. The LFI vulnerability can lead to unauthorized access to sensitive files, execution of arbitrary PHP code, and potential full server compromise.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit this vulnerability without needing any authentication, making it highly accessible.
• Arbitrary File Inclusion: By manipulating the mode parameter, attackers can include and execute arbitrary .php files on the server.
• Code Execution: If attackers can upload .php files to the server, they can execute arbitrary PHP code, leading to complete control over the server.

Exploitation Methods:

• File Inclusion: Attackers can include files from the server, potentially accessing sensitive information or configuration files.
• Remote Code Execution (RCE): If attackers can upload a malicious .php file and include it via the mode parameter, they can execute arbitrary code.
• Data Exfiltration: Attackers can read sensitive files, such as database credentials or configuration files, leading to data breaches.

3. Affected Systems and Software Versions

Affected Software:

• WP Travel Engine – Tour Booking Plugin – Tour Operator Software for WordPress
• Versions: All versions up to and including 6.6.7

Affected Systems:

• Any WordPress installation using the affected plugin versions.
• Servers hosting WordPress sites with the vulnerable plugin installed.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update the Plugin: Ensure that the WP Travel Engine plugin is updated to a version higher than 6.6.7, where the vulnerability is patched.
• Disable the Plugin: If an update is not immediately available, consider disabling the plugin until a patch is released.
• Monitor for Suspicious Activity: Implement monitoring to detect any unusual file access or code execution attempts.

Long-Term Mitigations:

• Regular Updates: Maintain a regular update schedule for all plugins and WordPress core.
• Access Controls: Implement strict access controls and limit the permissions of the web server user.
• Web Application Firewall (WAF): Deploy a WAF to filter out malicious requests and protect against LFI and RCE attacks.
• File Upload Restrictions: Ensure that file uploads are restricted to non-executable file types and are stored in non-web-accessible directories.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-7634 highlights the ongoing risk posed by vulnerable plugins in the WordPress ecosystem. Given the widespread use of WordPress, such vulnerabilities can have a significant impact, affecting millions of websites. This underscores the importance of regular security audits, timely updates, and robust monitoring practices.

6. Technical Details for Security Professionals

Vulnerable Code Snippets:

• FilterTripsHtml.php (Line 72):

  include($_GET['mode']);
  

• LoadTripsHtml.php (Line 27):

  include($_GET['mode']);
  

Exploitation Example: An attacker could craft a URL like:

http://example.com/wp-content/plugins/wp-travel-engine/includes/classes/Core/Controllers/Ajax/FilterTripsHtml.php?mode=../../../../../../etc/passwd

This would attempt to include the /etc/passwd file, potentially exposing user information on a Unix-based system.

Detection and Response:

• Log Analysis: Review web server logs for unusual mode parameter values.
• Intrusion Detection Systems (IDS): Configure IDS to detect and alert on suspicious file inclusion attempts.
• Incident Response: Have a predefined incident response plan to quickly address and mitigate any detected exploitation attempts.

Conclusion: CVE-2025-7634 represents a significant risk to WordPress sites using the WP Travel Engine plugin. Immediate action is required to update the plugin and implement additional security measures to protect against potential exploitation. Regular security assessments and proactive monitoring are essential to mitigate such vulnerabilities in the future.
