Cross-Site Scripting (XSS) is a vulnerability where attackers inject malicious scripts into web pages viewed by other users. This scanner identifies potential Content-Security-Policy (CSP) bypasses in Zendesk-powered websites, which could lead to XSS attacks. XSS vulnerabilities enable attackers to perform actions on behalf of users, steal session tokens, or redirect users to malicious websites. The exploitation of this vulnerability can result in unauthorized data access, modification, and theft. By detecting CSP bypasses, organizations can enhance their web security posture against XSS threats. Proactive detection aids in implementing appropriate defenses to mitigate these risks.

XSS vulnerabilities are often found where user-generated content is not properly sanitized. This scanner checks for the presence of Content-Security-Policy headers and attempts to exploit potential weaknesses using crafted payloads. It simulates potential attacks by injecting scripts via query parameters to assess if CSP rules are enforced correctly. The scanner navigates through targeted Zendesk endpoints and waits for potential XSS triggers to be activated. By analyzing the server's response and behavior, it determines if the CSP can be bypassed for script execution. Detecting such vulnerabilities allows web administrators to apply more stringent CSP configurations.

If an XSS vulnerability is exploited, attackers could gain the ability to execute arbitrary scripts in the user's context. This could result in user impersonation, unauthorized actions, or the manipulation of web content shown to the victim. Additionally, sensitive data such as authentication tokens or user credentials may be exposed, leading to further compromise. The impact of such exploitation might extend to reputation damage and violation of privacy regulations. It is crucial for organizations to address these vulnerabilities to protect users and maintain trust.
