CVE-2011-3377

First published: Fri Sep 30 2011(Updated: )

Deepak Bhole discovered a flaw in the Same Origin Policy (SOP) implementation in the IcedTea project Web browser plugin. A malicious applet could use this flaw to bypass SOP protection and open connections to any sub-domain of the second-level domain of the applet's origin, as well as any sub-domain of the domain that is the suffix of the origin second-level domain. For example, IcedTea-Web plugin allowed applet from some.host.example.com to connect to other.host.example.com, www.example.com, and example.com, as well as www.ample.com or ample.com.
