PHP iCalendar Cookie Data Traversal Local File Inclusion

medium Nessus Plugin ID 21083

Language:

Synopsis

The remote web server contains a PHP application that is affected by a local file include flaw.

Description

The remote host appears to be running PHP iCalendar, a web-based iCal file viewer / parser written in PHP.

The version of PHP iCalendar installed on the remote host fails to sanitize input to cookie data normally used to store language and template user preferences before using it in a PHP 'include()' function in 'functions/init.inc.php'. An unauthenticated attacker can exploit this issue to view arbitrary files and possibly to execute arbitrary PHP code on the affected host.

Successful exploitation of this issue does not necessarily depend on the setting of PHP's 'magic_quotes_gpc'. For code execution, it does, though, require that an attacker be able to write to files on the remote host, perhaps by injection into the web server's error log.

Note that there may also be a vulnerability in this version of PHP iCalendar in which an attacker can gain administrative access to the application by manipulating cookie values, although Nessus has not tested for it explicitly.

Solution

Unknown at this time.
