Improper URL Scheme Validation in Google Chrome WebUI Controller Factory

CVE-2015-1266 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:P/A:N

content/browser/webui/content_web_ui_controller_factory.cc in Google Chrome before 43.0.2357.130 does not properly consider the scheme in determining whether a URL is associated with a WebUI SiteInstance, which allows remote attackers to bypass intended access restrictions via a similar URL, as demonstrated by use of http://gpu when there is a WebUI class for handling chrome://gpu requests.
