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" References ========== [ 1 ] CVE-2006-1495 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1495 [ 2 ] CVE-2008-4303 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4303 [ 3 ] CVE-2008-4304 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4304 [ 4 ] CVE-2008-4305 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4305 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200812-20.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
