CVE-2024-9106 PoC — WordPress plugin Wechat Social login 安全漏洞

Description

Wechat Social login <= 1.3.0 - Authentication Bypass

介绍

# CVE-2024-9106
Wechat Social login <= 1.3.0 - Authentication Bypass

# Description:
The Wechat Social login plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 1.3.0. This is due to insufficient verification on the user being supplied during the social login. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id. This is only exploitable if the app secret is not set, so it has a default empty value. Just add uid=1 or change the id number to the account you want to login in as. Only works for wechat.
