Erjinzhi 10OA Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in Erjinzhi 10OA version 1.0, specifically within the '/trial/mvc/finder' endpoint. This issue arises from inadequate input sanitization of the 'name' parameter in GET requests, allowing remote attackers to inject arbitrary JavaScript payloads. The injected scripts are executed in the context of the user's browser, triggered by interactions such as mouse hovers.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where injected scripts are executed in the context of the victim's browser.

Reproduction

To reproduce this vulnerability, send a GET request to the '/trial/mvc/finder' endpoint with a 'name' parameter that includes a JavaScript payload, such as a script tag or an event handler. The injected script will be executed when the response is viewed in a browser, particularly if the payload is designed to run on mouse hover.

Remediation

It is recommended to implement proper input validation and output encoding for the 'name' parameter to prevent the injection of malicious scripts. Additionally, a Content Security Policy (CSP) can be applied to restrict the execution of unauthorized scripts.
