Executive Summary

The WP Job Portal plugin for WordPress contains a vulnerability in the function 'WPJOBPORTALcustomfields::removeFileCustom' present in all versions up to and including 2.4.9. This vulnerability arises from insufficient validation of file paths, allowing authenticated users with Subscriber-level access or higher to delete arbitrary files on the server.

Because the file path is not properly validated, attackers can specify files outside the intended scope to delete. This can lead to deletion of critical files such as 'wp-config.php', which can then be exploited to achieve remote code execution on the server.

Impact Analysis

This vulnerability can have severe impacts including unauthorized deletion of important files on the server hosting the WordPress site.

• Authenticated attackers with low-level access (Subscriber or above) can delete arbitrary files.
• Deletion of critical files like 'wp-config.php' can lead to remote code execution, allowing attackers to run malicious code on the server.
• Such unauthorized file deletions can disrupt website functionality, cause data loss, and compromise the security and integrity of the server.

Detection Guidance

This vulnerability allows authenticated users with Subscriber-level access or higher to delete arbitrary files on the server via the WP Job Portal plugin's 'WPJOBPORTALcustomfields::removeFileCustom' function due to insufficient file path validation.

Detection on your system can involve monitoring for unusual file deletion activities, especially targeting critical files such as wp-config.php or other important server files.

Since the vulnerability requires authenticated access, reviewing WordPress user activity logs for suspicious file deletion requests or unexpected plugin function calls related to WP Job Portal can help detect exploitation attempts.

Specific commands to detect exploitation attempts are not provided in the available resources.

Mitigation Strategies

To mitigate this vulnerability, immediately update the WP Job Portal plugin to version 2.5.0 or later, where security fixes addressing this issue have been applied.

Restrict or review user permissions to ensure that only trusted users have Subscriber-level or higher access, as the vulnerability requires authenticated access.

Monitor and audit file deletion activities on the server to detect any unauthorized or suspicious deletions.

If an immediate update is not possible, consider temporarily disabling the WP Job Portal plugin to prevent exploitation.

Compliance Impact

The vulnerability in the WP Job Portal plugin allows authenticated attackers with Subscriber-level access and above to delete arbitrary files on the server, potentially leading to remote code execution.

Such unauthorized file deletion and possible remote code execution can compromise the confidentiality, integrity, and availability of data stored on the affected server.

This kind of security breach can impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data against unauthorized access and modification.

Specifically, if personal data governed by GDPR or protected health information under HIPAA is stored or processed on the affected server, this vulnerability could lead to data breaches, unauthorized data alteration, or service disruption, all of which are violations of these regulations.
