What the vulnerability does

01Description

The atec Debug plugin for WordPress is vulnerable to remote code execution in all versions up to, and including, 1.2.22 via the 'custom_log' parameter. This is due to insufficient sanitization when saving the custom log path. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute code on the server.

Explanation of Vulnerability in Simple Terms

02Summary

atec Debug versions 1.2.22 and earlier contain a code injection vulnerability that allows authenticated administrators to execute arbitrary PHP code on the site. An attacker with high-level administrative privileges can inject malicious code through the application, leading to full compromise of confidentiality, integrity, and availability. No user interaction is required once an attacker gains admin access.
