Clickjacking Protection Misconfiguration Template

This report addresses a critical security vulnerability regarding Clickjacking Protection Misconfiguration within our application. Clickjacking Protection Misconfiguration occurs when the appropriate measures to prevent clickjacking attacks are not properly configured, leaving the application vulnerable to attacks where users are tricked into clicking on disguised or invisible elements. This report aims to detail the vulnerability, its potential impact, and recommendations for mitigation.

Description of the Vulnerability:

Clickjacking Protection Misconfiguration vulnerabilities arise when the X-Frame-Options or Content-Security-Policy (CSP) headers are not correctly configured to prevent the embedding of the application within an iframe or restrict which sites can embed the application. Without proper configuration, attackers can create malicious web pages that overlay the application with deceptive content, tricking users into unknowingly interacting with it, such as clicking on buttons or links.


The impact of Clickjacking Protection Misconfiguration can be severe, leading to security risks such as unauthorized actions performed by users, theft of sensitive information, or manipulation of user sessions. Attackers can exploit these vulnerabilities to trick users into performing unintended actions, such as making fraudulent transactions or revealing confidential data, potentially resulting in financial loss, reputational damage, or legal consequences for our organization.


The likelihood of exploitation depends on various factors, including the visibility and accessibility of the application within iframes, the security measures implemented to prevent clickjacking attacks, and the attacker's knowledge and motivation. However, given the ease of exploitation and the potential impact on user security and privacy, the risk associated with Clickjacking Protection Misconfiguration is significant if not properly mitigated.

Steps to Reproduce:

  1. Attempt to embed the application within an iframe on a malicious web page.
  2. Verify if the X-Frame-Options header is missing or set to allow embedding from any origin.
  3. Check if the Content-Security-Policy (CSP) header does not include the frame-ancestors directive or allows embedding from untrusted sources.
  4. Attempt to overlay the embedded application with deceptive content and trick users into interacting with it.

Recommendations for Developers:

  1. Configure X-Frame-Options Header: Set the X-Frame-Options header to DENY or SAMEORIGIN to prevent the application from being embedded within iframes from other domains.
  2. Implement Content-Security-Policy (CSP): Configure the Content-Security-Policy (CSP) header with the frame-ancestors directive to restrict which sites can embed the application, or use the frame-src directive to specify trusted sources for framing.


Addressing Clickjacking Protection Misconfiguration vulnerabilities is critical to protecting against unauthorized actions, data theft, and manipulation of user sessions within our application. By configuring the X-Frame-Options header and implementing Content-Security-Policy (CSP), we can mitigate the risks associated with Clickjacking Protection Misconfiguration and enhance the overall security posture of our systems.
