DESCRIPTION:
A vulnerability has been reported in IBM Lotus Domino, which can be
exploited by malicious people to bypass certain security
restrictions.

The vulnerability is caused due to an error in the Server Controller
authentication mechanism, which does not properly verify the
COOKIEFILE path before using it to retrieve a user's credentials.
This can be exploited to bypass the authentication mechanism by
providing a malicious UNC path to COOKIEFILE.

Successful exploitation may allow execution of arbitrary code.

SOLUTION:
Restrict access to the affected service to trusted hosts only.

PROVIDED AND/OR DISCOVERED BY:
