Google dork: "by Pivot - 1.40.5" +'Dreadwind' -pivotlog.net
vulnerability:
search.php - lines 98-109:
... // Set the template for the tags page if (!isset($Pivot_Vars['t']) || empty($Pivot_Vars['t'])) { if (isset($Weblogs[$Current_weblog]['extra_template']) && ($Weblogs[$Current_weblog]['extra_template']!="") ) { $template = $Weblogs[$Current_weblog]['extra_template']; } else { $template = $Weblogs[$Current_weblog]['archive_template']; } } else { $template = $Pivot_Vars['t']; }
$template_html = load_template($template); ...
't' argument is passed to load_template() function without checks
see load_template() function in /modules/module_parser.php - lines 778-797
... function load_template($basename) { global $template_cache, $Paths;
$filename = $Paths['templates_path'].$basename;
if (isset($template_cache[$basename])) { return $template_cache[$basename]; } else {
if (!(file_exists($filename))) { $filename = $Paths['templates_path']."entrypage_template.html"; } $filetext=implode("", file($filename)); // <----------------------------|_ lol !!!
$template_cache[$basename]=$filetext;
return $filetext; }
} ...
our argument is passed to a file() function, so, regardless of php settings, we can see php files at screen trough directory traversal attacks, including the configuration file (pv_cfg_settings.php), which cointains the admin credentials (username/md5 hash/sessions...)
note: 't' can be passed as GET or POST ----------------------------------------------------------------------------
