Super Socializer is a popular WordPress plugin designed to integrate social sharing, social login, and social comments functionalities into WordPress websites. It is widely used by website owners to enhance user engagement and simplify the login process through social media accounts. The plugin supports a variety of social networks and provides flexibility in customization, making it a preferred choice for improving social interactivity on WordPress sites. Its purpose is to facilitate social media integration, thereby increasing website traffic and user interaction. This plugin is developed by Heateor.
CVE-2023-2779 identifies a Cross-Site Scripting (XSS) vulnerability within the Super Socializer plugin versions prior to 7.13.52. This security flaw arises from the plugin's failure to properly sanitize and escape a parameter before it is output back onto the page. As a result, attackers can execute malicious scripts in the context of the user's browser, particularly targeting administrators and other high-privileged users on WordPress sites. This vulnerability can be exploited to steal cookies, hijack sessions, or perform actions on behalf of users.
The XSS vulnerability in the Super Socializer plugin occurs within the handling of specific parameters used in the social sharing, social login, and social comments functionalities. An attacker can craft malicious content that, when processed by the plugin, leads to the execution of arbitrary JavaScript code in the context of the victim's browser. This particular issue is exemplified in the plugin's handling of AJAX requests to the admin-ajax.php file, where unsanitized input within the urls parameter can trigger the vulnerability. The lack of proper input validation allows for the injection of scripts that can be executed in a reflected XSS attack.
Exploitation of this XSS vulnerability could have several detrimental effects. Attackers could leverage this flaw to execute scripts that steal cookies or session tokens, enabling unauthorized access to user accounts. It could also lead to the manipulation of web page content, redirecting users to malicious sites, or phishing attacks aiming to collect sensitive information. Furthermore, exploiting this vulnerability against administrators could compromise the entire WordPress site, leading to broader security breaches and data theft.
