DESCRIPTION:
Two vulnerabilities have been reported in Mahara, which can be
exploited by malicious users to conduct script insertion attacks and
by malicious people to conduct cross-site scripting attacks.

1) Input passed via the URL to e.g. htdocs/admin/users/changeuser.php
is not properly sanitised in htdocs/auth/lib.php before being returned
to the user after redirection to the login form. This can be exploited
to execute arbitrary HTML and script code in a user's browser session
in context of an affected site.

2) Input passed via "Insert/Edit Image" within an Edit blog is not
properly sanitised before being used. This can be exploited to insert
arbitrary HTML and script code, which will be executed in a user's
browser session in context of an affected site if malicious data is
viewed.

The vulnerabilities are reported in versions prior to 1.5.2 and prior
to 1.4.3.

SOLUTION:
Update to version 1.5.2 or 1.4.3.

PROVIDED AND/OR DISCOVERED BY:
1) The vendor credits Emanuel Bronshtein.
2) Reported by the vendor.
