CVE-2024-53723 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the acbaltaci Google Plus Share and +1 Button plugin, which is used to integrate Google Plus sharing functionality on websites. This vulnerability allows attackers to perform stored Cross-Site Scripting (XSS) attacks by exploiting the lack of proper request validation and input sanitization. Specifically, the plugin fails to verify the authenticity of requests, enabling malicious actors to craft forged requests that, when processed by the vulnerable plugin, store malicious scripts within the application. These scripts execute in the browsers of users who visit the compromised pages, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The affected versions include all versions up to and including 1.0, with no patch currently available. The vulnerability was reserved and published in late November and early December 2024, respectively. Although no known exploits are reported in the wild, the combination of CSRF and stored XSS significantly increases the risk profile. The plugin is primarily used in WordPress environments, which are widely adopted globally, especially in North America, Europe, and parts of Asia. The absence of a CVSS score necessitates an expert severity assessment based on the vulnerability's characteristics.

The impact of CVE-2024-53723 is significant for organizations using the affected plugin. Successful exploitation can lead to stored XSS attacks, which allow attackers to execute arbitrary JavaScript in the context of users' browsers. This can result in theft of sensitive information such as session cookies, personal data, or credentials, enabling further compromise of user accounts or administrative access. Additionally, attackers may perform unauthorized actions on behalf of users, including changing settings or injecting further malicious content. The CSRF aspect means attackers can trick authenticated users into submitting malicious requests without their knowledge, increasing the attack surface. For organizations, this can lead to reputational damage, data breaches, and regulatory compliance issues. Since the plugin is used on websites, the availability impact is generally low, but integrity and confidentiality impacts are high. The lack of a patch means the vulnerability remains exploitable until mitigated or the plugin is removed.

To mitigate CVE-2024-53723, organizations should immediately assess whether their websites use the acbaltaci Google Plus Share and +1 Button plugin, especially versions up to 1.0. If found, the following steps are recommended: 1) Disable and remove the vulnerable plugin until a secure update is released. 2) Implement Web Application Firewall (WAF) rules to detect and block CSRF and XSS attack patterns targeting this plugin. 3) Employ anti-CSRF tokens in all forms and requests to ensure request authenticity. 4) Sanitize and validate all user inputs rigorously to prevent script injection. 5) Monitor web server and application logs for suspicious activities indicative of exploitation attempts. 6) Educate web administrators about the risks of using outdated or unmaintained plugins. 7) Consider replacing the plugin with a maintained and secure alternative that provides similar functionality without known vulnerabilities. 8) Regularly update all plugins and CMS components to their latest versions to reduce exposure to known vulnerabilities.
