CVE-2004-1155: Microsoft Ie

High severity, CVSS 7.5. EPSS: 12.6% chance of exploitation in the next 30 days.

Internet Explorer 5.01 through 6 allows remote attackers to spoof arbitrary web sites by injecting content from one window into another window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability. NOTE: later research shows that Internet Explorer 7 on Windows XP SP2 is also vulnerable.

Affected products

• Microsoft Ie: version 5.0.1 only; version 5.2.3 only; version 6.0 only; version 7.0 only
• Microsoft Internet Explorer: version 5.0.1 only; version 5.5 only; version 6.0 only
