[原文]IIS 4.0 and 5.0 .ASP pages send the same Session ID cookie for secure and insecure web sessions, which could allow remote attackers to hijack the secure web session of the user if that user moves to an insecure session, aka the "Session ID Cookie Marking" vulnerability.
Microsoft IIS .ASP Session ID Disclosure and Hijacking
Remote / Network Access
Loss of Confidentiality,
Loss of Integrity
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.
Currently, there are no known workarounds or upgrades to correct this issue. However, Microsoft has released a patch to address this vulnerability.
