TikiWiki unserialize() Function Arbitrary Code Execution

high Nessus Plugin ID 61733

Language:

Synopsis

The remote web server hosts an application that allows arbitrary code execution.

Description

The version of the TikiWiki installed on the remote host contains a flaw that could allow a remote attacker to execute arbitrary code. The 'unserialize()' function is not properly sanitized before being used in the 'lib/banners/bannerlib.php', 'tiki-print_multi_pages.php', 'tiki-send_objects.php' and 'tiki-print_pages.php' scripts.

Successful exploitation of the vulnerability requires that the 'multiprint' feature is enabled, the PHP setting 'display_errors' must be set to 'On', and a PHP version older than 5.3.4 must be in use to allow poison NULL bytes in filesystem-related functions.

Solution

Upgrade to version 8.4 or later.
