DESCRIPTION:
Aliaksandr Hartsuyeu has discovered a vulnerability in PHP Event
Calendar, which can be exploited by malicious users to manipulate
certain information and conduct script insertion attacks.

Input passed to the "username" and "password" fields when updating
user information isn't properly sanitised before being stored. This
can be exploited to manipulate another user's user information and
inject arbitrary HTML and script code, which will be executed in a
user's browser session in context of an affected site when the
malicious user data is viewed.

The vulnerability has been confirmed in version 1.5. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
