How the mentioned CVE works
CVE-2017-6078 exploits a critical flaw in the authentication mechanism between the SKYSEA Client View agent and its management console. The communication occurs over a custom TCP protocol. The vulnerability exists because the client agent does not properly validate authentication packets received from a console. An attacker can craft a malicious TCP packet with a specific size and send it directly to the client agent’s listening port. This malformed packet can bypass the authentication process entirely. Once the fake authentication is accepted, the attacker can communicate with the agent as a trusted management console. This privileged access allows the attacker to send further commands, ultimately leading to the execution of arbitrary operating system commands on the target system with SYSTEM-level privileges. The attack is unauthenticated and network-exploitable.
Platform: SKYSEA Client View
Version: 11.221.03 and earlier
Vulnerability: Improper Authentication
Severity: Critical
date: 2017-03-08
Prediction: 2017-04-15
What Undercode Say:
Analytics
`nmap -p 22351 `
`!/bin/python3 Craft malicious auth packet`
`import socket; sock = socket.socket(); sock.connect((TARGET_IP, 22351)); sock.send(MALICIOUS_PAYLOAD)`
How Exploit:
Attacker sends a specially crafted TCP packet to port 22351, bypassing authentication to gain console privileges and execute arbitrary system commands remotely without user interaction.
Protection from this CVE
Apply vendor patch. Block port 22351 at network perimeter. Upgrade to latest version.
Impact:
Complete system compromise. Unauthorized remote code execution with highest privileges.
