Bug affected | Kerio MailServer prior 6.0.3 |
Bug not affected | Kerio MailServer newer than 6.0.2 |
Bug vulnerability class | Unknown |
Bug description | The remote host is running a version of Kerio MailServer prior to 6.0.3. There is an undisclosed flaw in the remote version of this server which might allow an attacker to execute arbitrary code on the remote host. |
Bug solution | The server should be deactivated or de-installed if not necessary. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8025). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software. Upgrade the software to the latest version. |
