Synopsis
========
Multiple vulnerabilities have been discovered in phpCollab allowing for
remote injection of shell commands, PHP code and SQL statements.
Background
==========
phpCollab is a web-enabled groupware and project management software
written in PHP. It uses SQL-based database backends.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/phpcollab <= 2.5_rc3 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
Description
===========
Multiple vulnerabilities have been found in phpCollab:
* rgod reported that data sent to general/sendpassword.php via the
loginForm parameter is not properly sanitized before being used in an
SQL statement (CVE-2006-1495).
* Christian Hoffmann of Gentoo Security discovered multiple
vulnerabilites where input is insufficiently sanitized before being
used in an SQL statement, for instance in general/login.php via the
loginForm parameter. (CVE-2008-4303).
* Christian Hoffmann also found out that the variable
$SSL_CLIENT_CERT in general/login.php is not properly sanitized
before being used in a shell command. (CVE-2008-4304).
* User-supplied data to installation/setup.php is not checked before
being written to include/settings.php which is executed later. This
issue was reported by Christian Hoffmann as well (CVE-2008-4305).
Impact
======
These vulnerabilities enable remote attackers to execute arbitrary SQL
statements and PHP code. NOTE: Some of the SQL injection
vulnerabilities require the php.ini option "magic_quotes_gpc" to be
disabled. Furthermore, an attacker might be able to execute arbitrary
shell commands if "register_globals" is enabled, "magic_quotes_gpc" is
disabled, the PHP OpenSSL extension is not installed or loaded and the
file "installation/setup.php" has not been deleted after installation.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
phpCollab has been removed from the Portage tree. We recommend that
users unmerge phpCollab:
# emerge --unmerge "www-apps/phpcollab"
