CVE-2022-43166 - Stored XSS in Rukovoditel v3.2.1 Global Entities Allows For Arbitrary Web Script Execution

In recent times, security researchers have uncovered yet another vulnerability that puts unsuspecting users at risk. This time, it pertains to the Rukovoditel v3.2.1, a popular open-source project management software. The vulnerability, designated as CVE-2022-43166, is a stored cross-site scripting (XSS) flaw that affects the software's Global Entities feature. This post will explore this vulnerability in detail, including an overview of the affected software, an explanation of cross-site scripting, and a discussion of the exploit that takes advantage of this vulnerability. Additionally, the post will provide example code snippets and links to the original references for users who want to learn more.

Affected Software

Rukovoditel is a versatile, open-source project management software designed to help teams streamline their daily workflows. It contains all of the features that one would expect from a modern project management tool, including task management, time tracking, reporting, and more. Users can find more information about Rukovoditel on its official website: https://www.rukovoditel.net/.

Cross-Site Scripting (XSS) Overview

Cross-site scripting is a common web-based vulnerability that arises from the ability of an attacker to inject malicious scripts into a website or application. These scripts then execute within the context of the user's browser, potentially leading to the theft of sensitive information, the manipulation of application functionality, or the complete defacing of a webpage.

The Exploit

The CVE-2022-43166 vulnerability stems from an injection point within the Global Entities feature of Rukovoditel v3.2.1. An authenticated attacker can exploit this vulnerability by crafting a malicious payload and injecting it into the "Name" parameter after clicking "Add New Entity." Upon executing this payload, the stored XSS vulnerability allows the attacker to run arbitrary web scripts or HTML.

The following code snippet demonstrates a simple proof-of-concept for exploiting this vulnerability

<script>alert('XSS');</script>

Exploitation of this vulnerability could have catastrophic consequences, especially in cases where the injected script sends sensitive user data to a remote attacker-controlled server or manipulates the application to perform actions against the user's will.
