Even for servers that do not have these particular bugs, the general variant of the attack, which works against any SSLv2 server, can be conducted in under 8 hours at a total cost of $440.”

“You’re just as much at risk if your site’s certificate or key is used anywhere else on a server that does support SSLv2,” security researchers noted. “Common examples include SMTP, IMAP, and POP mail servers, and secondary HTTPS servers used for specific web applications.”

SSLv2 certificate has been offered since 90s and noted to be vulnerable to get years, so most servers now use a distinct protocol. Nevertheless, it’s right now emerged that even permitting SSLv2 is actually a threat to modern servers and consumers.
