Description

Microsoft IIS contains a flaw that may allow a malicious user to access and hijack Session ID cookies. The issue is due to .ASP in IIS using the same Session ID cookies on secure and non-secure web pages. By controlling the communications channel and requesting the non-secure pages on the same website, a remote attacker can obtain the Session ID cookie in plaintext and use it to connect to the user's session with the secure page, resulting in a loss of confidentiality and integrity.
