TITLE:
telepark.wiki Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA37391

VERIFY ADVISORY:
http://secunia.com/advisories/37391/

DESCRIPTION:
Some vulnerabilities have been reported in telepark.wiki, which can
be exploited by malicious people to conduct cross-site scripting
attacks, bypass certain security restrictions, disclose sensitive
information, and compromise a vulnerable system.

1) Input appended to the URL after index.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
the context of an affected site.

2) An error due to improper authentication verification in
/ajax/deletePage.php can be exploited to delete pages without any
user credentials.

3) An error due to improper authentication verification in
/ajax/deleteComment.php can be exploited to delete comments without
any user credentials.

4) Input passed via various parameters to multiple scripts is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local resources via
directory traversal attacks.

Examples:
http://[host]/getjs.php?css=[code]
http://[host]/getcsslocal.php?css=[code]
http://[host]/upload.php?group=[code]

5) A vulnerability is caused due to the /ajax/addComment.php script
not properly verifying uploaded files. This can be exploited to
execute arbitrary PHP code by uploading a PHP file with a specially
crafted file name containing a NULL byte.

The vulnerabilities are reported in versions prior to 2.4.25.

SOLUTION:
Update to version 2.4.25 or later.
