* Use a more secure command line building methodPeter Wu2014-07-208-73/+100
| | | | | | | | | | | | | | | | | | | Previously, a command is built by string concatenation. Here, the distinction between a value and multiple params got lost. Solve this by using an array for shell arguments. As the escaping is now removed from the `rrd_gen_graph` function, the canvas style needs to manually add those quotes to make the JS code still work. That only supports double-quotes, so hopefully nobody creates a name with a double quote as that would break the fragile JS command line parser. Separate the rrdtool options from the rrdtool graph command to make the `$graph_type == 'canvas'` option work (it would otherwise not understand the `rrdtool graph - -a PNG` option). Merge the SVG and PNG cases as they are the same except for the Content-Type header. Fix a missing html escape in a debug style.
* security: Add missing input validation for pluginPeter Wu2014-07-201-1/+1
| | | | | | | This is a security bug. The contents of the file are not immediately disclosed, but it could disclose environment information to the attacker (when display_errors=1 and an ancient PHP version is used that does not check for '\0' in `file_exists()`).
* Fix type confusionPeter Wu2014-07-202-4/+8
| | | | | | | | | index.php expects that collectd_hosts() always return an array for array_diff. Since an empty array evaluates to FALSE anyway, do not change the type and just return the empty array. In base.php, if no files are returned, the loop is never called and three variables are not initialized. Do it now.
* Defensive programming: more urlencode/htmlentitiesPeter Wu2014-07-204-52/+61
| | | | | | | | | | | | | | | | | | Make build_url return an URL, not HTML. This separates presentation from data. plugin_header's return value is unused, remove the unnecessary return. At places where `printf("<tag att='%s'>", $x);` is used, it is now converted to `printf("<tag att=\"%s\">", htmlentities($x));` since the single quote is not escaped by default by htmlentities. In case the canvas style is used, JS should use `textContent` instead of `innerHTML` to avoid reading `&quot;` instead of `"`. Nobody (should) use(s) IE6 anymore, so it is a safe change. While at it, use the standard charset attribute of meta to specify the character set (UTF-8).

* Escape HTML in GET-provided hostnameNicolas Iooss2014-06-302-4/+4
| | | | | | | A malicious user can enter javascript code in "h" GET parameter and this code gets executed because this parameter is copied in the HTML output without any escaping. This patch escape the output before it is checked it is valid.

| | | | | | | array_merge resets the index, while in case of $this->colors and $this->legend, we'd like to keep the index. An irq plugin sample: array(1 => 1, 'ERR' => 'ERR') must not become array(0 => 1, 'ERR' => 'ERR') after an array_merge.

* graph.php: use JSON plugins instead of including PHP plugin filesPim van den Berg2014-05-1296-2792/+2248
| | | | | | | | | | | | A couple of big changes here. A lot of logic moved to graph.php. The PHP plugin files have been rewritten to JSON. In these JSON files *everything* is optional. Also *NOT* having a JSON plugin file won't block you from having a graph. The JSON will just make the graphs prettier (by having a title, y-axis title, legend, colors, etc..). The Collectd types.db file is parsed and used to determine RRD content. When things are not defined in the JSON it will fallback to a default.

* type/base: always use rainbow_colors and overwrite them afterwardsPim van den Berg2014-05-031-3/+4
| | | | | | Since the previous commit [type/base: show tinstances not defined in $this->order in graph] all type instances that are not defined in the plugin, are colored black. This way you always have nice colors.
* type/base: show tinstances not defined in $this->order in graphPim van den Berg2014-05-031-6/+5
| | | | | | Previously if $this->order was defined in a graph, only type instances that were defined in $this->order showed up in the graph. Now it merges $this->order and the type instances.

| | | | | | | | | This means we have to check the return value of these functions for example before doing a foreach. We can't just do a foreach and assume the return value of a function is an array, while it can be false and results in a PHP warning. Closes: https://github.com/pommi/CGP/pull/68
