Apache HTTP Server and IBM HTTP Server contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when function ap_resolve_env() in server/util.c expands environment variable constructs from configuration files such as .htaccess or httpd.conf. For an attacker to exploit the flaw they would need to carefully craft malicious configuration files and have write access to the legitimate copies. This flaw may lead to a loss of confidentiality.
