Microsoft Internet Explorer fails to properly validate cached HTTPS contents, allowing an attacker to obtain information or spoof information on a secure web site.
The HTTPS protocol is used to provide authentication, encryption, integrity, and non-repudiation services to web applications. Microsoft Internet Explorer (IE) does not properly validate cached HTTPS content. An attacker could exploit this vulnerability by creating a web site with the same host name as the legitimate HTTPS protected web site. When the attacker's web site is viewed, the contents are cached. If the attacker redirects the victim's browser to the legitimate web site, the attacker's cached contents are then displayed within the context of that web site. The cached content could include script code, images, or other locally cached items.
An attacker may be able to spoof information on a secure web site. Using script, an attacker may be able to retrieve cookies or other information from a secure web session.
