DESCRIPTION:
Two vulnerabilities have been reported in the PMK Shadowbox extension
for TYPO3, which can be exploited by malicious people to disclose
potentially sensitive information and conduct cross-site scripting
attacks.

1) Certain input passed to filenames is not properly verified before
being used to download files. This can be exploited to download
arbitrary files from local resources.

2) Certain input passed to filenames is not properly sanitised before
being returned to the user. This can be exploited to execute arbitrary
HTML and script code in a user's browser session in context of an
affected site.

The vulnerabilities are reported in version 3.2.0 and prior.

SOLUTION:
Update to version 3.2.1.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
