Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
A vulnerability in DBMail could allow for passwordless login to any
account under certain configurations.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
DBMail is a mail storage and retrieval daemon that uses SQL databases
as its data store. IMAP and POP3 can be used to retrieve mails from the
database.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-mail/dbmail < 2.2.9 >=3D 2.2.9=
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
A vulnerability in DBMail's authldap module when used in conjunction
with an Active Directory server has been reported by vugluskr. When
passing a zero length password to the module, it tries to bind
anonymously to the LDAP server. If the LDAP server allows anonymous
binds, this bind succeeds and results in a successful authentication to
DBMail.
Impact
=3D=3D=3D=3D=3D=3D
By passing an empty password string to the server, an attacker could be
able to log in to any account.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All DBMail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dnet-mail/dbmail-2.2.9"
