CVE-2008-4304 Information

Description

general/login.php in phpCollab 2.5 rc3 and earlier allows remote attackers to execute arbitrary commands via shell metacharacters in unspecified input related to the SSL_CLIENT_CERT environment variable. NOTE: in some environments SSL_CLIENT_CERT always has a base64-encoded string value which may impose constraints on injection for typical shells.
