Google Maps RU Content-Security-Policy Bypass Scanner

Google Maps RU is a popular mapping service used by individuals and businesses worldwide for navigation and location-based services. It provides APIs that are integrated into numerous websites and applications for displaying interactive maps, driving directions, and location searches. Businesses use it to provide customers with an easy way to locate their physical locations. Developers leverage its wide range of functionalities for building sophisticated location-aware applications. The service plays a pivotal role in various sectors, such as logistics, tourism, and retail, by optimizing route planning and improving user experience. Due to its extensive use, ensuring the security of its integrations is critical to prevent potential exploitation by attackers.

The vulnerability detected in this scanner pertains to a misconfigured Content-Security-Policy within Google Maps RU. It allows for the potential bypass of security controls meant to prevent Cross-Site Scripting (XSS) attacks. XSS vulnerabilities allow malicious code to be executed in the context of a user's browser. Attackers could exploit this to steal session cookies, deface websites, or redirect users to malicious sites. Detecting such vulnerabilities is crucial for maintaining the integrity and security of web applications that rely on Google Maps RU. The vulnerability requires immediate attention to prevent any potential exploitation scenarios.

The technical details of the vulnerability involve improper configuration of the Content-Security-Policy header, which should restrict the execution of untrusted scripts but fails to do so. The vulnerable endpoint in this case is any web application using Google Maps RU with this weak CSP configuration. Attackers can inject malicious scripts through legitimate Google Maps API calls. One such vector involves injecting a script tag that points to Google Maps’ own script, potentially bypassing the CSP and executing the injected script. This method largely hinges on using `alert(1)` within a callback parameter as part of a payload, proving the CSP bypass capability.

If exploited, attackers could execute arbitrary scripts in the user's browser. This could lead to the theft of sensitive information, such as authentication credentials or personal data, stored in users' sessions or cookies. Additionally, attackers could deliver malware or redirect users to phishing sites. Such attacks could undermine users' trust and lead to potential financial and reputational damage to affected organizations. Therefore, mitigation of this vulnerability is of utmost importance to safeguard against these possible outcomes.
