Kerio MailServer IMAP Server Login Command Denial of Service Vulnerability Vulnerability Scan


Vulnerability Scan Summary
Checks how KMS IMAP server responds to login requests

Detailed Explanation for this Vulnerability Test

Synopsis :

The remote IMAP server is prone to denial of service attacks.

Description :

The remote host is running Kerio MailServer, a commercial mail server
available for Windows, Linux, and Mac OS X platforms.

it receives certain malformed IMAP LOGIN commands. An unauthenticated
remote attacker can exploit this issue to deny access to legitimate
users.

Note that the application may not terminate immediately but only after
an administrator acknowledges a console message.
