SECUNIA ADVISORY ID:
SA20323

VERIFY ADVISORY:
http://secunia.com/advisories/20323/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
Open-Xchange 0.x
http://secunia.com/product/6735/

DESCRIPTION:
Cemil Degirmenci has reported a security issue in Open-Xchange, which
potentially can be exploited by malicious people to bypass certain
security restrictions.

The problem is caused due to a default user with known username and
password being added to the ldap-server server during installation
(mailman/secret). This can be exploited to gain access to the IMAP
server, or to gain access to the system if the ldap-server is used
for pam authentication.

The security issue has been reported in version 0.8.2.

Note: The problem reportedly only affects the open-source version of
Open-Xchange.

SOLUTION:
The security issue will reportedly be fixed in the next version.

Change the password and the logon shell of the "mailman" user.
