Attack-Flow Graph

Executive Summary

This vulnerability in AirControl 1.4.2 allows unauthenticated attackers to execute arbitrary system commands remotely by injecting malicious Java expressions through the /.seam endpoint. Attackers craft a specially constructed URL containing these Java expressions, which the application executes with its system privileges, leading to remote code execution without needing to authenticate.

Impact Analysis

The vulnerability can lead to a complete compromise of the affected system since attackers can execute arbitrary commands with the application's system privileges. This can result in unauthorized access, data theft, system manipulation, or disruption of services.
