CVE-2008-3173: Microsoft Internet Explorer

Medium severity, CVSS 6.8. EPSS: 11.3% chance of exploitation in the next 30 days.

Microsoft Internet Explorer allows web sites to set cookies for domains that have a public suffix with more than one dot character, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session, aka "Cross-Site Cooking." NOTE: this issue may exist because of an insufficient fix for CVE-2004-0866.
