Key facts

Description

Interpretation conflict in phpBB 2.0.17, with remote avatars and avatar uploading enabled, allows remote authenticated users to inject arbitrary web script or HTML via an HTML file with a GIF or JPEG file extension, which causes the HTML to be executed by a victim who views the file in Internet Explorer, which renders malformed image types as HTML, enabling cross-site scripting (XSS) attacks. NOTE: it could be argued that this vulnerability is due to a design flaw in Internet Explorer (CVE-2005-3312) and the proper fix should be in that browser; if so, then this should not be treated as a vulnerability in phpBB.
