CVE-2022-2633 in All-in-One Video Gallery Plugin
Summary
by MITRE • 09/06/2022
The All-in-One Video Gallery plugin for WordPress is vulnerable to arbitrary file downloads and blind server-side request forgery via the 'dl' parameter found in the ~/public/video.php file in versions up to, and including 2.6.0. This makes it possible for unauthenticated users to download sensitive files hosted on the affected server and forge requests to the server.

The CVE-2022-2633 vulnerability affects the All-in-One Video Gallery plugin for WordPress, representing a critical security flaw that exposes systems to unauthorized file access and server-side request forgery attacks. This vulnerability resides within the plugin's video.php file where an improperly validated 'dl' parameter allows malicious actors to manipulate file download operations. The issue impacts all versions up to and including 2.6.0, making it a widespread concern for WordPress installations using this particular plugin. The vulnerability's classification aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, and CWE-918, which covers server-side request forgery vulnerabilities.
The technical exploitation of this vulnerability occurs through the manipulation of the 'dl' parameter in the video.php file, enabling unauthenticated attackers to request arbitrary files from the server's filesystem. This blind server-side request forgery capability allows threat actors to access sensitive information including configuration files, database credentials, and other system resources that should remain protected. The vulnerability's impact extends beyond simple file access as it can facilitate further reconnaissance and potentially lead to complete system compromise. Attackers can leverage this flaw to download WordPress core files, plugin configurations, or even server-side scripts that contain sensitive data.
Operationally, this vulnerability creates significant risk for WordPress administrators who may not immediately detect the unauthorized file access attempts. The blind nature of the server-side request forgery means that attackers can make requests to internal services without direct visibility of responses, making detection more challenging. Organizations using the affected plugin version face potential data breaches, system compromise, and unauthorized access to sensitive information. The vulnerability particularly affects websites that host sensitive content or have plugins that store credentials in accessible locations, as the flaw can be exploited without authentication credentials.
Mitigation strategies for CVE-2022-2633 require immediate action from affected organizations. The primary recommendation involves upgrading the All-in-One Video Gallery plugin to a version that addresses this vulnerability, typically version 2.6.1 or later. System administrators should also implement network-level restrictions to prevent access to the vulnerable video.php endpoint and consider implementing web application firewalls to detect and block malicious requests. Additionally, organizations should conduct comprehensive security audits to identify any unauthorized file access that may have occurred and review server logs for evidence of exploitation attempts. The vulnerability's alignment with ATT&CK technique T1071.004 for application layer protocol manipulation emphasizes the need for robust network monitoring and traffic analysis to detect suspicious patterns in file download requests.
