A security vulnerability (CVE-2024-31843) has been discovered in the Italtel Embrace Version 1.6.4, a widely used unified communication system. This vulnerability allows authenticated users to execute arbitrary commands on the server's Operating System. This long-read post dives deep into the vulnerability details, provides code snippets, shares relevant links to the original references, and explores exploitation methods.

Vulnerability Details

Italtel Embrace, a popular Unified Communication and Collaboration (UC&C) platform, is found to be vulnerable to a Command Injection attack in version 1.6.4. The Web application running on Embrace fails to properly validate and clean up the input data received from the users. This security flaw potentially allows authenticated users to execute malicious commands at the server operating system level, compromising the entire system and the users' data.

The following are the steps to exploit the mentioned vulnerability

1. An attacker gains access to the Italtel Embrace Web application as an authenticated user. This can be achieved either by stealing login credentials or using social engineering techniques.

2. The attacker identifies a parameter in the Web application that is not being properly sanitized or checked before it is processed on the server side.

3. The attacker prepares a malicious command injection payload containing arbitrary server commands. An example of a simple payload can be:

| id |

This simple payload allows the attacker to run the id command on the server, which reveals the user permissions and details of the server.

4. The attacker successfully injects the payload using the vulnerable parameter in the Web application. If the application fails to sanitize the input and processes the command, it will execute the attacker's arbitrary commands on the server's Operating System.
