Two vulnerabilities were identified in MailEnable, which could be exploited by attackers to execute arbitrary commands or create and rename arbitrary directories.
The first issue is due to stack overflow errors in the IMAP service (MEIMAPS.EXE) that does not properly handle specially crafted mailbox names passed to "select", "create", "delete", "rename", "subscribe" and "unsubscribe" commands, which could be exploited by authenticated attackers to compromise a vulnerable server.
The second vulnerability is due to an input validation error in the IMAP service (MEIMAP.EXE) that does not properly handle specially crafted mailbox names passed to the "create" and "rename" commands, which may be exploited by authenticated attackers to create or rename arbitrary directories.
