VNC Security Type Enforcement Failure Remote Authentication Bypass
The version of VNC server running on the remote host is affected by the following vulnerabilities : - A flaw exists in RealVNC due to an error when handling password authentication. A remote attacker can exploit this to bypass authentication by using a specially crafted request in which the clien...
RealVNC Remote Authentication Bypass Vulnerability
Description RealVNC is susceptible to an authentication-bypass vulnerability. This issue is due to a flaw in the authentication process of the affected package. Exploiting this issue allows attackers to gain unauthenticated, remote access to the VNC servers. RealVNC 4.1.1 is vulnerable to this...
CVE-2006-2206
The CVE-2006-2206 entry concerns UltraVNC 1.0.1 whose MS-Logon scheme uses weak XOR encryption for challenge/response. This weak cryptography permits an attacker on the network to sniff credentials and decrypt passwords, enabling privilege escalation.
Vulnerability in the way [email protected] handles MS-Logon Authentication.
