| Bug vulnerability class | Denial Of Service |
| Bug description | The target is running at least one instance of MailEnable's IMAP service. A flaw exists in MailEnable Professional Edition versions 1.5a-d that results in this service crashing if it receives a SEARCH command. An authenticated user could send this command either on purpose as a denial of service attack or unwittingly since some IMAP clients, such as IMP and Vmail, use it as part of the normal login process. |
| Bug solution | Upgrade to MailEnable Professional 1.5e. |
