Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities have been discovered in phpCollab allowing for |
19 |
remote injection of shell commands, PHP code and SQL statements. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
phpCollab is a web-enabled groupware and project management software |
25 |
written in PHP. It uses SQL-based database backends. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 www-apps/phpcollab <= 2.5_rc3 Vulnerable! |
34 |
------------------------------------------------------------------- |
35 |
NOTE: Certain packages are still vulnerable. Users should migrate |
36 |
to another package if one is available or wait for the |
37 |
existing packages to be marked stable by their |
38 |
architecture maintainers. |

Description |
41 |
=========== |
42 |
|
43 |
Multiple vulnerabilities have been found in phpCollab: |
44 |
|
45 |
* rgod reported that data sent to general/sendpassword.php via the |
46 |
loginForm parameter is not properly sanitized before being used in an |
47 |
SQL statement (CVE-2006-1495). |
48 |
|
49 |
* Christian Hoffmann of Gentoo Security discovered multiple |
50 |
vulnerabilites where input is insufficiently sanitized before being |
51 |
used in an SQL statement, for instance in general/login.php via the |
52 |
loginForm parameter. (CVE-2008-4303). |
53 |
|
54 |
* Christian Hoffmann also found out that the variable |
55 |
$SSL_CLIENT_CERT in general/login.php is not properly sanitized |
56 |
before being used in a shell command. (CVE-2008-4304). |
57 |
|
58 |
* User-supplied data to installation/setup.php is not checked before |
59 |
being written to include/settings.php which is executed later. This |
60 |
issue was reported by Christian Hoffmann as well (CVE-2008-4305). |
61 |
|
62 |
Impact |
63 |
====== |
64 |
|
65 |
These vulnerabilities enable remote attackers to execute arbitrary SQL |
66 |
statements and PHP code. NOTE: Some of the SQL injection |
67 |
vulnerabilities require the php.ini option "magic_quotes_gpc" to be |
68 |
disabled. Furthermore, an attacker might be able to execute arbitrary |
69 |
shell commands if "register_globals" is enabled, "magic_quotes_gpc" is |
70 |
disabled, the PHP OpenSSL extension is not installed or loaded and the |
71 |
file "installation/setup.php" has not been deleted after installation. |
72 |
|
73 |
Workaround |
74 |
========== |
75 |
|
76 |
There is no known workaround at this time. |
77 |
|
78 |
Resolution |
79 |
========== |
80 |
|
81 |
phpCollab has been removed from the Portage tree. We recommend that |
82 |
users unmerge phpCollab: |
83 |
|
84 |
# emerge --unmerge "www-apps/phpcollab" |
