CVE-2015-7188
|
| Summary | Security researcher Michał Bentkowski reported that adding white-space characters to hostnames that are IP addresses can bypass same-origin policy. This flaw was caused by trailing whitespaces being evaluated differently when parsing IP addresses instead of alphanumeric hostnames. This could lead to a cross-site script (XSS) attack. In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts. |
