Previous versions (such as GroupWise 7.x) of GroupWise are likely also vulnerable but are no longer supported. Customers on earlier versions of GroupWise should, at a minimum, upgrade their GWIAs and associated Domains to version 8.02HP2 in order to secure their system.
SituationThe GroupWise Internet Agent (GWIA) has a vulnerability in the way that it parses the TZID variable within a received VCALENDAR message, which could potentially allow an unauthenticated remote attacker to execute arbitrary code on vulnerable installations of GWIA. This vulnerability affects GWIA running on all supported server OS platforms (Windows, SuSE Linux, & NetWare).
ResolutionTo resolve this security issue, update GWIA to version 8.02 Hot Patch 2 (or later).
