Firefox/Mozilla let attackers inject content into other sites

CVE-2004-1156 · published 21 years ago
Summary

Versions of Firefox before 1.0.1 and Mozilla before 1.7.6 can be tricked into displaying fake web pages by inserting content from one browser window into another that belongs to a different site. This could cause users to believe they are on a trusted site when they are not. Upgrade to the latest browser releases to close this risk.

Mozilla before 1.7.6, and Firefox before 1.0.1, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target 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.
