Patch Published: N/A
CVE [?]: CVE-2006-4602
CPE [?]: cpe:/a:tikiwiki:tikiwiki

Synopsis

The remote web server contains a PHP script that allows uploading of arbitrary files.

Description

The 'jhot.php' script included with the version of TikiWiki installed on the remote host allows an unauthenticated attacker to upload arbitrary files to a known directory within the web server's document root. Provided PHP's 'file_uploads' setting is enabled, which is true by default, this flaw can be exploited to execute arbitrary code on the affected host, subject to the privileges of the web server user id.

Solution

Either remove the affected 'jhot.php' script or upgrade to TikiWiki 1.9.5 or later.

Public Exploits

Target Network Port(s): 80
Target Asset(s): Services/www
Exploit Available: True (Metasploit Framework, Exploit-DB, Core Impact)
