info:
|
|
name: Sunhillo SureLine <8.7.0.1.1 - Unauthenticated OS Command Injection
|
|
author: gy741
|
|
severity: critical
|
|
description: Sunhillo SureLine <8.7.0.1.1 is vulnerable to OS command injection. The /cgi/networkDiag.cgi script directly incorporated user-controllable parameters within a shell command, allowing an attacker to manipulate the resulting command by injecting valid OS command input. The following POST request injects a new command that instructs the server to establish a reverse TCP connection to another system, allowing the establishment of an interactive remote shell session.
|
|
remediation: |
|
|
Upgrade to Sunhillo SureLine version 8.7.0.1.1 or later to mitigate this vulnerability.
