Loading vulnerability…
jQuery versions before 3.0.0 improperly handle cross-domain Ajax requests when the dataType option is omitted. A response served with the text/javascript content type can be automatically executed, allowing cross-site scripting in the context of a victim's browser.

This repository contains a single JavaScript file, 'xss.js', which demonstrates a proof-of-concept (POC) exploit for CVE-2015-9251, a cross-site scripting (XSS) vulnerability in jQuery versions prior to 3.0.0. The file contains a simple payload: an alert box that would be executed if the payload is successfully injected and executed in a vulnerable web application. There are no network endpoints, IP addresses, or file paths hardcoded in the exploit. The repository serves as a minimal demonstration of the XSS vulnerability, suitable for testing or educational purposes.
This repository provides a Proof of Concept (PoC) exploit for CVE-2015-9251, a Cross-Site Scripting (XSS) vulnerability in jQuery versions prior to 3.0.0. The repository contains three files: a README.md describing the vulnerability, a Python script (server.py) that starts a local HTTP server on port 8081 to serve a malicious JavaScript payload, and an HTML file (CVE-2015-9251.html) that acts as the exploit trigger. When the HTML file is opened in a browser and the 'Check' button is clicked, it uses jQuery to make an AJAX request to the local server for 'malicious.js'. The server responds with a JavaScript payload (alert(document.domain);), demonstrating the XSS vulnerability. The exploit is a classic browser-based XSS PoC, requiring the user to run the server and open the HTML file locally. No external targets or real-world endpoints are hardcoded; all actions occur on localhost for demonstration purposes.
This repository provides a Proof of Concept (PoC) exploit for CVE-2015-9251, a Cross-Site Scripting (XSS) vulnerability in jQuery versions prior to 3.0.0. The exploit demonstrates how an attacker can inject arbitrary JavaScript code via the 'callback' parameter in a JSONP request, due to insufficient sanitization in affected jQuery versions. The repository contains two files: a JavaScript file (CVE-2015-9251.js) with the exploit code, and a README.md with detailed instructions and background. The exploit is executed in a browser context and requires the target web application to use a vulnerable jQuery version and accept user-controlled JSONP callback parameters. The main endpoint targeted in the PoC is 'https://example.com/api?callback=alert(document.cookie)', which, if vulnerable, will execute the injected JavaScript and potentially expose sensitive data such as cookies.
This repository contains a proof-of-concept exploit for CVE-2015-9251, a cross-origin resource sharing (CORS) vulnerability in jQuery versions prior to 3.0.0. The main file, 'CVE-2015-9251.html', is an HTML page that loads a vulnerable version of jQuery and provides a button. When the button is clicked, it triggers a cross-origin AJAX request to 'https://sakurity.com/jqueryxss'. If the response is JavaScript (with Content-Type: text/javascript), it will be executed in the context of the page, demonstrating an XSS vulnerability. The repository is structured simply, with a single HTML exploit file and a minimal README. The exploit demonstrates the vulnerability but does not weaponize it beyond showing the XSS vector.
