CVE-2024-43919

YARPP <= 5.30.10 - Missing Authorization

Description

The YARPP – Yet Another Related Posts Plugin plugin for WordPress is vulnerable to unauthorized access due to a missing capability check in the ~/includes/yarpp_pro_set_display_types.php file in all versions up to, and including, 5.30.10. This makes it possible for unauthenticated attackers to set display types.

Type: plugin
CVSS Score: 5.3
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
CVE: CVE-2024-43919
Slug: yet-another-related-posts-plugin

Info

Not a clue what this actually does.

POC

Here's an example of a raw HTTP request that exploits the vulnerability in the YARPP plugin:

GET /wp-content/plugins/yet-another-related-posts-plugin/includes/yarpp_pro_set_display_types.php?ypsdt=false&types[]=post&types[]=page HTTP/1.1
Host: example.com

In this request:

• The ypsdt parameter is set to false to bypass the initial check in the code.
• The types[] parameter is used to specify the display types to set. In this example, post and page are passed as the types.
• The Host header specifies the target WordPress site hosting the vulnerable YARPP plugin.

When this request is sent to a WordPress site with a vulnerable version of the YARPP plugin installed, it will set the display types without requiring any authentication or authorization.
