CVSS v3.1
Official Description
qemu-kvm before 0.11.0 disables VNC authentication when the password is cleared, which allows remote attackers to bypass authentication and establish VNC sessions.
Technical Analysis
CVE-2011-0011 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
