Description |
A remote overflow exists in Kerio MailServer. The integrated web server fails to validate user input to the "folder" variable in the "add_acl" module resulting in a buffer overflow in several variables. With a specially crafted request, an attacker can cause the execution of arbitrary code resulting in a loss of integrity.

Technical |
If an attacker sets the folder as "~adminlocalhost/INBOX" and clicks it, the mail server will stop with an access violation. The add_acl module "add_name" variable is also vulnerable to an overflow when provided an overly long name.
An attacker must have an account in the webmail system to exploit the buffer overflow, or build a specially crafted URL and trick a registered user with open session into clicking the link.
