Ayco Portal Content-Security-Policy Bypass Scanner

The Ayco Portal is used by financial institutions and individual investors for wealth management and financial planning. It serves as a digital platform for accessing personalized financial services and managing investment portfolios. The portal is commonly utilized by clients requiring sophisticated financial solutions and investment advice. Ayco Portal offers clients the ability to monitor and manage their financial transactions securely online. Its features are intended for wealth managers and clients emphasizing on data-driven investment strategies. Security of client data and compliance with industry standards are a high priority for the users of such platforms.

This scanner detects potential Cross-Site Scripting (XSS) vulnerabilities in the Ayco Portal. XSS is a type of security vulnerability that can be used by attackers to inject malicious scripts into web pages. Such vulnerabilities can expose sensitive user information and compromise the user’s browsing session. By matching specific patterns in headers and other parts of the request, the scanner can identify the presence of a Content-Security-Policy bypass. This kind of vulnerability can lead to unauthorized actions being performed on behalf of users in their browsers. Proper identification and remediation of XSS vulnerabilities are crucial for maintaining the security of web applications.

The scanner employs a mix of HTTP and headless navigations to test for the presence of a Content-Security-Policy header in responses from Ayco Portal. The scanner includes a fuzzing mechanism that attempts to inject JavaScript code into the application through its query strings. It specifically checks for the ability to execute a payload that may reflect or allow dynamic script execution, circumventing the normal CSP barriers. The tool waits for certain events in the DOM to confirm whether the vulnerability is present. The successful match of predefined patterns signifies the presence of XSS vulnerabilities requiring attention.

Exploiting a Cross-Site Scripting vulnerability can have several detrimental effects. Attackers could hijack user sessions and perform actions on behalf of authenticated users without detection. There’s a risk of data theft as malicious scripts can extract sensitive information from users. Users may also be redirected to phishing websites unknowingly, leading to further exploitation. If exploited, such vulnerabilities can undermine trust in the Ayco Portal's ability to securely handle user data. In the worst case, it could lead to regulatory non-compliance and loss of client data integrity.
