Synopsis |
19 |
======== |
20 |
|
21 |
Multiple vulnerabilities in eGroupWare may lead to execution of |
22 |
arbitrary PHP code, the ability to upload malicious files and |
23 |
cross-site scripting attacks. |
24 |
|
25 |
Background |
26 |
========== |
27 |
|
28 |
eGroupWare is a suite of web-based group applications including |
29 |
calendar, address book, messenger and email. |
30 |
|
31 |
Affected packages |

Description |
40 |
=========== |
41 |
|
42 |
A vulnerability has been reported in FCKEditor due to the way that file |
43 |
uploads are handled in the file |
44 |
editor/filemanager/upload/php/upload.php when a filename has multiple |
45 |
file extensions (CVE-2008-2041). Another vulnerability exists in the |
46 |
_bad_protocol_once() function in the file |
47 |
phpgwapi/inc/class.kses.inc.php, which allows remote attackers to |
48 |
bypass HTML filtering (CVE-2008-1502). |
49 |
|
50 |
Impact |
51 |
====== |
52 |
|
53 |
The first vulnerability can be exploited to upload malicious files and |
54 |
execute arbitrary PHP code provided that a directory is writable by the |
55 |
webserver. The second vulnerability can be exploited by remote |
56 |
attackers via a specially crafted URL in order to conduct cross-site |
57 |
scripting attacks. |
58 |
|
59 |
Workaround |
60 |
========== |
61 |
|
62 |
There is no known workaround at this time. |
63 |
|
64 |
Resolution |
65 |
========== |
66 |
|
67 |
All eGroupWare users should upgrade to the latest version: |
68 |
|
69 |
# emerge --sync |
70 |
# emerge --ask --oneshot --verbose ">=www-apps/egroupware-1.4.004" |
71 |
