Description

The Telenium Online Web Application is vulnerable due to a PHP endpoint accessible to unauthenticated network users that improperly handles user-supplied input. This vulnerability occurs due to the insecure termination of a regular expression check within the endpoint. Because the input is not correctly validated or sanitized, an unauthenticated attacker can inject arbitrary operating system commands through a crafted HTTP request, leading to remote code execution on the server in the context of the web application service account.

Attack-Flow Graph

Executive Summary

The vulnerability in the Telenium Online Web Application is caused by a PHP endpoint that is accessible without authentication and improperly handles user input. Specifically, the endpoint fails to securely terminate a regular expression check, allowing an attacker to inject arbitrary operating system commands through a crafted HTTP request. This leads to remote code execution on the server with the privileges of the web application service account.

Impact Analysis

This vulnerability can have severe impacts as it allows an unauthenticated attacker to execute arbitrary commands on the server remotely. This can lead to full compromise of the server, unauthorized access to sensitive data, disruption of services, and potential use of the server as a foothold for further attacks within the network.
