Description Andrej Nemec 2016-11-07 09:06:01 UTC

Multiple security issues were reported in Moodle CMS and announced via CVENEW mail.

CVE-2016-9186:

Unrestricted file upload vulnerability in the "legacy course files" and
"file manager" modules in Moodle 3.1.2 allows remote authenticated
users to execute arbitrary code by uploading a file with an executable
extension, and then accessing it via unspecified vectors.

This one should be Windows specific.

CVE-2016-9187:

Unrestricted file upload vulnerability in the double extension support
in the "image" module in Moodle 3.1.2 allows remote authenticated users
to execute arbitrary code by uploading a file with an executable
extension, and then accessing it via unspecified vectors.

CVE-2016-9188:

Cross-site scripting (XSS) vulnerabilities in Moodle CMS on or before
3.1.2 allow remote attackers to inject arbitrary web script or HTML via
the s_additionalhtmlhead, s_additionalhtmltopofbody, and
s_additionalhtmlfooter parameters.
