CVE-2023-2624 Scanner

The KiviCare WordPress Plugin is widely used for managing healthcare practice management applications within the WordPress platform. It is primarily utilized by medical professionals, clinics, and healthcare facilities to streamline and automate the workflow processes like appointment scheduling, patient management, and billing. This plugin is connected to the WordPress environment, making it flexible and easily accessible for users accustomed to this ecosystem. The plugin serves a critical function in ensuring that all healthcare management needs are met digitally through WordPress's interface. Its adaptability makes it particularly popular across a wide user base, ranging from small clinics to larger healthcare organizations. Ensuring its security is vital, given that it handles sensitive patient information and operational data which are valuable to users.

Cross-Site Scripting (XSS) is a prevalent vulnerability in web applications that allows attackers to insert malicious scripts into webpages viewed by other users. This specific vulnerability occurs due to the improper sanitization and escaping of the 'filterType' parameter in the KiviCare WordPress Plugin before version 3.2.1. When the application fails to handle this parameter securely, attackers can craft an input that causes the browser to execute malicious scripts. These scripts can manipulate the webpage content, steal sensitive information like session cookies, or even perform actions on behalf of the user without their consent. Addressing this vulnerability is crucial as it poses significant risks to the integrity and confidentiality of the web application.

The technical aspect of the vulnerability lies in the 'filterType' parameter within the KiviCare WordPress Plugin. When this parameter is not adequately sanitized and escaped, an attacker can inject a script payload via reflected XSS, which executes when the affected page is loaded. The vulnerable endpoint exists in the plugin's AJAX calls, where unsanitized user input can be embedded directly into the HTML structure of the application. If the vulnerability is exploited, the attacker's code could execute arbitrary scripts in a user's browser. The vulnerability typically involves sending a crafted request to the application to exploit the interpreted script context, allowing unauthorized access or data theft.

If malicious individuals exploit this vulnerability, the possible effects are significant. Attackers could gain unauthorized access to sensitive data, such as user credentials and session identifiers, leading to information disclosure. There is also the potential for session hijacking, where an attacker can assume the identity of a legitimate user. Additionally, the scripts could potentially manipulate the application to perform undesired actions on the user's behalf, leading to unauthorized operations or transactions. Users' trust could be diminished, and the application's overall integrity and reputation might be compromised, affecting its user base and market position.
