Active Mixed Content

How to Find & Report Active Mixed Content 

Active mixed content is considered a security risk because an attacker could potentially intercept or modify the active content, compromising the integrity and security of the page. For example, an attacker could inject malicious code into an insecure JavaScript file or modify the content displayed within an insecure iframe.

What is Mixed Content ? 

Mixed content refers to a situation where a web page contains both secure (HTTPS) and non-secure (HTTP) elements. It typically arises when a webpage is loaded over a secure connection (HTTPS), but certain resources within that page, such as images, scripts, or stylesheets, are referenced using insecure HTTP URLs.

The HTTP Content-Security-Policy (CSP) block-all-mixed-content directive prevents loading any assets over HTTP when the page uses HTTPS. All mixed content resource requests are blocked, including both active and passive mixed content

How to Find Active Mixed Content ?

 

STEP #1: . Open any site and copy its domain name.

STEP #2: Then open any mixed content checker online site, search the domain in it, you will get the URL(site) of active mixed content, open it.

STEP #3: After opening the link, you will have the site in your browser, then press F12, you will get the URL(HTTP) of the active mixed content.

Impact : 

Active mixed content can be exploited in man-in-the-middle attacks. If the active content is loaded over an insecure connection, an attacker positioned between the user and the server can intercept and modify the content, potentially compromising user interactions, stealing sensitive information, or performing other malicious activities.

Active mixed content poses a security risk because it can be intercepted or modified by attackers. If an insecure script or plugin is loaded, it could be tampered with to inject malicious code into the webpage, potentially leading to unauthorized access, data theft, or other security breaches.

Mitigation :

If your webpage relies on external services or APIs that provide active content, verify that they support HTTPS and update the URLs accordingly. Contact the service providers for guidance on migrating to HTTPS if necessary.

 Update the URLs of all active content to use a secure connection (HTTPS). This includes scripts, iframes, plugins, or any other active elements. Ensure that the references to these resources use "https://" instead of "http://".
