Elgg 1.7.6 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by vendors/simpletest/test/visual_test.php and certain other files.

Directory traversal vulnerability in _css/js.php in Elgg 1.5, when magic_quotes_gpc is disabled, allows remote attackers to read arbitrary files via a .. (dot dot) in the js parameter. NOTE: some of these details are obtained from third party information.
