Multiple PHP remote file inclusion vulnerabilities in b2evolution allow remote attackers to execute arbitrary PHP code via a URL in the (1) inc_path parameter to (a) a_noskin.php, (b) a_stub.php, (c) admin.php, (d) contact.php, (e) default.php, (f) index.php, and (g) multiblogs.php in blogs/; the (2) view_path and (3) control_path parameters to blogs/admin.php; and the (4) skins_path parameter to (h) blogs/contact.php and (i) blogs/multiblogs.php.  NOTE: this issue is disputed by CVE, since the inc_path, view_path, control_path, and skins_path variables are all initialized in conf/_advanced.php before they are used
