PACKAGE : imp
SUMMARY : Session hijacking vulnerability
DATE : 2001-11-16 18:24:00
ID : CLA-2001:437

RELEASES : 5.0, 5.1, 6.0, 7.0

DESCRIPTION
Imp is a webmail system which uses the Horde[3] framework.
Joao Pedro Goncalves reported[1] a vulnerability[2] in the Imp
webmail system which could be used by a remote attacker to access a
victim's email.
It is possible to include a script in an URL via html tags. Since
these tags are not treated appropriately in previous versions (<=
2.2.6) of Imp, such scripts can be executed by an unsuspecting user
if clicked on when viewing an email. By emailing such a crafted URL
to an user and having this user click on it, the attacker is able to
retrieve the authentication cookies used in the webmail session, thus
gaining access to the user's webmail account.
SOLUTION
The authors have released a new version to addresses this
vulnerability. It is recommended that all administrators deploying
the Imp webmail system apply the upgrade.
