Status: ModifiedMedium (5)—
LiveConnect in Mozilla Firefox before 2.0.0.13 and SeaMonkey before 1.1.9 does not properly parse the content origin for jar: URIs before sending them to the Java plugin, which allows remote attackers to access arbitrary ports on the local machine. NOTE: this is closely related to CVE-2008-1195.
CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
