Improper Flag Setting in Mozilla Firefox Allows for URL Spoofing

CVE-2016-5268 · MEDIUM Severity

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

Mozilla Firefox before 48.0 does not properly set the LINKABLE and URI_SAFE_FOR_UNTRUSTED_CONTENT flags of about: URLs that are used for error pages, which makes it easier for remote attackers to conduct spoofing attacks via a crafted URL, as demonstrated by misleading text after an about:neterror?d= substring.
