Overview

The BadgeOS WordPress plugin (versions up to 3.7.1.6) contains an Insecure Direct Object Reference vulnerability identified as CVE-2023-2172. The vulnerability was discovered by Alex Thomas from Wordfence and publicly disclosed on July 5, 2023. The issue affects multiple handler functions within the plugin, including badgeosupdatestepsajaxhandler, badgeosupdateawardstepsajaxhandler, badgeosupdatedeductstepsajaxhandler, and badgeosupdateranksreqstepsajaxhandler (NVD).

Technical details

The vulnerability stems from improper validation and authorization checks in several AJAX handler functions. The CVSS v3.1 base score is 4.3 (Medium) with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N. This indicates that the vulnerability requires network access and low privileges to exploit, with potential impact limited to integrity (Wordfence).

Impact

When exploited, this vulnerability allows authenticated attackers with subscriber-level permissions or higher to overwrite arbitrary post titles within the WordPress installation. This could lead to content manipulation and potential site defacement (NVD).

Mitigation and workarounds

Site administrators should update the BadgeOS plugin to a version newer than 3.7.1.6. The vulnerability has been patched in the plugin's source code, with fixes implemented in multiple files including steps-ui.php, award-steps-ui.php, deduct-steps-ui.php, and rank-steps-ui.php (WordPress Plugin).
