Date published: Jan 13, 2011

*Vulnerability Information*

Class: Directory Traversal

Remotely Exploitable: Yes

Locally Exploitable: Yes

*Software Description*

Provides end-to-end FlexPod management and automation across physical,

virtual, compute, storage and network resources.

Create internal private clouds rapidly with internal standards and

procedures to maximize the infrastructure investments.

*Vulnerability Description*

jQuery File Tree is a configurable, AJAX file browser plugin for the jQuery

javascript library utilised within the Cloupia application framework.

Unauthenticated access to this module allows a remote attacker to browse

the entire file system of the host server, beyond the realm of the web

service itself.

Cloupia are aware of this flaw and are releasing a patch to mitigate

access. End users are urged to update immediately by contacting the vendor.

* **Technical Description*

The following process performed as an attacker to exploit this

vulnerability would be as follows:

The code for the jQuery File Tree Java-Server-Page file reads as follows:

<%@ page

String dir = request.getParameter("dir");

if (dir == null) {

return;

}

if (dir.charAt(dir.length()-1) == '\\') {

dir = dir.substring(0, dir.length()-1) + "/";

} else if (dir.charAt(dir.length()-1) != '/') {

dir += "/";

}

if (new File(dir).exists()) {

String[] files = new File(dir).list(new FilenameFilter() {

public boolean accept(File dir, String name) {

return name.charAt(0) != '.';

}

});

Arrays.sort(files, String.CASE_INSENSITIVE_ORDER);

out.print("<ul class=\"jqueryFileTree\" style=\"display:

none;\">");

// All dirs

for (String file : files) {

out.print("<li class=\"directory

collapsed\"><a href=\"#\" rel=\"" + dir + file + "/\">"

+ file + "</a></li>");

}

}

// All files

for (String file : files) {

if (!new File(dir, file).isDirectory()) {

int dotIndex = file.lastIndexOf('.');

String ext = dotIndex > 0 ?

file.substring(dotIndex + 1) : "";

out.print("<li class=\"file ext_" + ext +

"\"><a href=\"#\" rel=\"" + dir + file + "\">"

+ file + "</a></li>");

}

}

out.print("</ul>");
