Google Maps content-security-policy-bypass-via Scanner

Google Maps is a widely used mapping service developed by Google, providing numerous features like street maps, street views, and real-time traffic conditions, making it a valuable tool for logistics and navigation. Businesses and developers embed Google Maps in their applications and websites to enhance user experience. The Google Maps API allows developers to integrate maps into various applications, providing geographical information and location-based services. Its ability to offer detailed location data aids in various sectors such as transport, tourism, and service delivery, offering route planning and proximity search. Businesses rely on Google Maps for advertising and to attract customers by precisely marking their physical locations on the digital map. Its usage spans globally, serving millions of users daily for both personal and professional purposes.

Cross-Site Scripting (XSS) vulnerabilities occur when an application includes user-supplied data in web pages without properly validating or encoding it, allowing attackers to execute arbitrary scripts in the context of other users. This particular vulnerability is a CSP bypass related to Google Maps which can potentially lead to XSS attacks. It targets the Content-Security-Policy implemented by websites using Google Maps, allowing for potential injection and execution of malicious scripts. XSS can lead to various problems, including the theft of session cookies, allowing attackers to impersonate legitimate users. Understanding and detecting XSS vulnerabilities is crucial for maintaining the security and integrity of web applications. This type of vulnerability is prevalent in dynamic content websites where user interaction is heavily involved.

The technical details involve exploiting Google Maps API through script injection by manipulating Content-Security-Policy headers. The vulnerable endpoint is typically the URL where Google Maps API is implemented, and the vulnerable parameter may include external script sources. This vulnerability exploits the way CSP is configured by unsuspecting developers, who fail to restrict script sources strictly. The payload used in detection includes injecting a script tag referencing an external Google Maps API script. Exploit success is determined by observing script execution within the browser context, bypassing the CSP. This kind of vulnerability emphasizes the need for strict CSP management and careful validation of external resources.

Exploiting this vulnerability can lead to significant security threats, including unauthorized script execution, data theft, and user session hijacking. Attackers may perform phishing attacks by manipulating the visual content displayed to users. Victims of such exploits could experience unauthorized actions carried out in their name, leading to financial and reputational damage. The integrity and confidentiality of the web application's data are compromised, potentially allowing attackers to spread further malware or hijack user credentials. Detecting and mitigating this vulnerability early is crucial for maintaining safe web environments for all users involved. Organizations must ensure their CSPs are correctly implemented to avoid such exploitation.
