A Reflected Cross-Site Scripting (XSS) vulnerability has been discovered in the eDoc Intelligence eDoc Employee Job Application plugin for WordPress, which markets itself as the "Best WordPress Job Manager for Employees". This security vulnerability specifically affects versions n/a through 1.13 of the plugin. If left unpatched, this vulnerability could allow malicious actors to inject and execute arbitrary JavaScript code on the target site, potentially leading to theft of sensitive user information, session hijacking, and website defacement, among other serious consequences.

Exploit Details

The vulnerability results from "Improper Neutralization of Input During Web Page Generation", which means that the plugin fails to properly validate and sanitize user-supplied input before including it in the web page output. This specific vulnerability lies in the way the plugin handles input fields such as the "search" parameter. When a user submits a search query through the plugin, the input is not properly sanitized, allowing malicious scripts from untrusted sources to be executed in a user's browser.

A simple proof-of-concept exploit demonstrating this vulnerability could look like this

http://vulnerablewebsite.com/edoc-job-application-page/?search=<script>alert('XSS')</script>;

When visiting the above URL, instead of simply displaying the search results for the query, the user's browser would execute the JavaScript inside the angle brackets, in this case displaying a pop-up alert with the message "XSS".

For more technical details and information regarding this vulnerability, you can refer to the following sources:

3. Verify that your WordPress installation is also up-to-date, with the latest security patches and the most recent version of PHP and MySQL installed.
4. Employ a web application firewall (WAF) to block known malicious inputs and to help mitigate XSS vulnerabilities.
5. Regularly perform security audits and vulnerability scans on your website to ensure no other vulnerabilities are present.
