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"
