CVE-2023-44012 Scanner

mojoPortal is a popular content management system (CMS) used to build websites and web applications. Developed and maintained by the community, it is known for its ease of use and flexibility. It is employed by web developers, designers, and individuals looking for an intuitive web platform. mojoPortal allows users to create and manage dynamic content quickly. The CMS supports various features, such as blogs, forums, and e-commerce, making it versatile for multiple use cases. Its user-friendly interface and robust functionality make it an attractive choice for both personal and enterprise purposes.

The Cross-Site Scripting (XSS) vulnerability allows attackers to inject malicious scripts into web pages viewed by other users. This vulnerability can be exploited to execute scripts in the context of a user's browser, potentially leading to data theft or account compromise. It arises when applications do not properly sanitize user input in web requests. XSS vulnerabilities are a significant security risk because they can affect all users interacting with the compromised application. By leveraging this vulnerability, an attacker can manipulate the behavior of web pages and steal sensitive information. Proper input validation and output encoding are essential to prevent XSS attacks.

The vulnerability in mojoPortal occurs in its handling of the 'helpkey' parameter within the Help.aspx component. Injecting a script into this parameter can trigger an execution of arbitrary code on a victim's browser session. A common payload for such an attack is embedding an alert() function using SVG elements, simulating a harmless event. The system does not adequately filter these inputs, resulting in scripts being executed unintentionally. An attacker might craft a URL containing the malicious code and trick users into visiting it, thereby executing the code. This vulnerability’s criticality is amplified when victim interaction is required to exploit the flaw.

If exploited, this Cross-Site Scripting vulnerability can have several adverse effects. Attackers can steal cookies, session tokens, or other sensitive data that the browser uses to authenticate users. The compromised sessions could be used to impersonate users and gain unauthorized access to their accounts. Additionally, with a successful XSS attack, attackers might even spread malware to other users by injecting malicious scripts into the website content. The reputation of the web application could be affected, as users may lose trust due to security concerns. Finally, undisclosed user information may be exposed, leading to privacy violations and potential legal ramifications.
