Description:
rgod has discovered two vulnerabilities in PHP iCalendar, which can be exploited by malicious people to disclose potentially sensitive information and to compromise a vulnerable system.
1) Input passed to the "cookie_language" and the "cookie_style" parameters in the "phpicalendar" cookie is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.
The vulnerability may be related to:
SA17328
2) Missing access control to the calendar upload directory can be exploited to upload arbitrary PHP files by passing a specially-crafted PUT request with a filename containing a NULL character in the "X-WR-CALNAME" parameter to publish.ical.php.
Successful exploitation requires that "phpicalendar_publishing" is set to 1 in config.inc.php.
The vulnerabilities have been confirmed in version 2.21. Other versions may also be affected.
