DESCRIPTION:
Some vulnerabilities have been discovered in Wikipad, which can be
exploited by malicious users to manipulate certain data and by
malicious people to disclose potentially sensitive information and to
conduct cross-site scripting and cross-site request forgery attacks.

1) Input passed to the "id" parameter in pages.php is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

2) Input passed to the "id" parameter in pages.php (when "action" is
set to "edit") is not properly verified before being used to access
files. This can be exploited to view and modify  files with a "*.txt"
extension through directory traversal attacks.

Successful exploitation to modify files requires editing rights.

3) The application allows users to perform certain actions via HTTP
requests without performing proper validity checks to verify the
requests. This can be exploited to e.g. manipulate certain data when
a logged-in user with editing rights visits a specially crafted web
page.

The vulnerabilities are confirmed in version 1.6. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified. Do not browse untrusted web sites or follow untrusted links
while being logged-in to the application.
