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"
