DESCRIPTION:
Tatercrispies has reported a vulnerability in Invision Gallery, which
can be exploited by malicious people to conduct script insertion
attacks.
The vulnerability is caused due to an input validation error in the
image upload handling. This can exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site by uploading a specially crafted valid image containing embedded
HTML and script code with an image file extension not matching the
image type (e.g. a valid GIF file with a ".jpg" file extension).
This is related to:
SA17295
Successful exploitation requires that the malicious image is accessed
directly in the Microsoft Internet Explorer browser (i.e. not
referenced via an image tag).
SOLUTION:
Edit the source code to ensure that images are properly validated
before being uploaded.
