Atomicorp WAF Research Note: CVE-2024-9193

WHMpress <= 6.3-revision-0 - Unauthenticated Local File Inclusion to Arbitrary Options Update

Research Notes

This page documents research related to exploit techniques, attack behaviors, testing results, and WAF rule interactions associated with this vulnerability.

Research finding: this note documents observed WAF protections relevant to exploit techniques associated with this vulnerability.

These notes are not intended to represent the full set of vulnerabilities mitigated by Atomicorp products and should not be interpreted as a coverage matrix, certification list, or census of protected CVEs.

Atomicorp WAF protections are primarily designed around attack techniques and exploit behaviors rather than individual vulnerability identifiers. A published research note documents a positive research finding related to that CVE. If a CVE is absent from these notes, no conclusion should be drawn about protection status.

Vulnerability Description

The WHMpress - WHMCS WordPress Integration Plugin plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 6.3-revision-0 via the whmpress_domain_search_ajax_extended_results() function. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included. This makes it possible for unauthenticated attackers to update arbitrary options on the WordPress site. Utilizing the /admin/services.php file, this can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.
