Synopsis
========
Multiple vulnerabilities in eGroupWare may lead to execution of
arbitrary PHP code, the ability to upload malicious files and
cross-site scripting attacks.
Background
==========
eGroupWare is a suite of web-based group applications including
calendar, address book, messenger and email.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/egroupware < 1.4.004 >= 1.4.004
Description
===========
A vulnerability has been reported in FCKEditor due to the way that file
uploads are handled in the file
editor/filemanager/upload/php/upload.php when a filename has multiple
file extensions (CVE-2008-2041). Another vulnerability exists in the
_bad_protocol_once() function in the file
phpgwapi/inc/class.kses.inc.php, which allows remote attackers to
bypass HTML filtering (CVE-2008-1502).
Impact
======
The first vulnerability can be exploited to upload malicious files and
execute arbitrary PHP code provided that a directory is writable by the
webserver. The second vulnerability can be exploited by remote
attackers via a specially crafted URL in order to conduct cross-site
scripting attacks.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All eGroupWare users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/egroupware-1.4.004"
