Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2019-25273 is an unquoted service path vulnerability found in Easy-Hide-IP version 5.0.0.3, specifically in the EasyRedirect service. The service executable path "C:\\Program Files\\Easy-Hide-IP\\rdr\\EasyRedirect.exe" is not enclosed in quotes. This allows local attackers to exploit the way Windows interprets paths with spaces, potentially injecting malicious executables.'}, {'type': 'paragraph', 'content': 'By placing a malicious executable in a location that Windows searches before the legitimate service executable, an attacker with local access can execute arbitrary code with elevated privileges.'}] [1, 2]

Impact Analysis

This vulnerability can allow a local attacker to escalate their privileges on the affected system by executing arbitrary code with the same privileges as the EasyRedirect service, which runs under the LocalSystem account.

Successful exploitation can lead to full system compromise, including unauthorized access to sensitive data, modification of system settings, and installation of persistent malware.
