-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : imp SUMMARY : Session hijacking vulnerability DATE : 2001-11-16 18:24:00 ID : CLA-2001:437 RELEVANT 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.
