# Vuln Title: The CollabNet Subversion Edge Management Frontend does not # implement clickjacking protection # # Date: 28.06.2015 # Author: otr # Software Link: https://www.open.collab.net/downloads/svnedge # Vendor: CollabNet # Version: 4.0.11 # Tested on: Fedora Linux # Type: Clickjacking # # Risk: Medium # Status: public/fixed # Fixed version: 5.0 Timeline: 2014-10-09 Flaw Discovered 2014-10-20 Vendor contacted 2014-10-21 Vendor response 2014-12-08 Vendor fix proposal 2014-12-08 Extension of embargo to 19.4.2015 2015-05-04 Extension of embargo until release of version 5.0 2015-05-18 Release of version 5.0 and public disclosure Summary: It might be possible for a web page controlled by an attacker to load the content of this response within an iframe on the attacker's page. The application's response does not set a suitable X-Frame-Options header in order to prevent framing attacks. Fix proposal: To effectively prevent framing attacks, the application should return a response header with the name X-Frame-Options and the value DENY to prevent framing altogether, or the value SAMEORIGIN to allow framing only by pages on the same origin as the response itself. Vendor fix: X-Frame-Options is set by default to DENY. It is configurable.
