CVE-2011-1773

17
FAUCET Score

CVE-2011-1773 describes a vulnerability in virt-v2v versions prior to 0.8.4, affecting products like Red Hat Enterprise Linux and virt-v2v, where the VNC console password is not preserved during guest conversion. This allows local attackers to bypass VNC authentication by connecting without a password. With a CVSS score of 4.4 (AV:L/AC:M/Au:N/C:P/I:P/A:P), this vulnerability has a low attack complexity and requires local access, potentially leading to partial confidentiality, integrity, and availability compromise. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, indicating a low current threat landscape.
