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 request forgery attacks.

1) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. delete blog posts by tricking
a logged in administrative user into visiting a malicious web site.

2) Certain input passed via Pieform select box options is not
properly sanitised before being displayed to the user. 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
when the malicious data is being viewed.

The vulnerabilities are reported in versions prior to 1.2.7 and
1.3.4.

SOLUTION:
Update to version 1.2.7 or 1.3.4.

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