AV:N/AC:L/Au:N/C:P/I:P/A:P

Variant of the "IIS Cross-Site Scripting" vulnerability as originally discussed in MS:MS00-060 (CVE-2000-0746) allows a malicious web site operator to embed scripts in a link to a trusted site, which are returned without quoting in an error message back to the client. The client then executes those scripts in the same context as the trusted site.

AV:N/AC:L/Au:N/C:P/I:P/A:P

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.

AV:N/AC:L/Au:N/C:P/I:P/A:P

Vulnerabilities in IIS 4.0 and 5.0 do not properly protect against cross-site scripting (CSS) attacks. They allow a malicious web site operator to embed scripts in a link to a trusted site, which are returned without quoting in an error message back to the client. The client then executes those scripts in the same context as the trusted site, aka the "IIS Cross-Site Scripting" vulnerabilities.

Infoleak
AV:N/AC:M/Au:N/C:P/I:P/A:N

The undocumented TRACK method in Microsoft Internet Information Services (IIS) 5.0 returns the content of the original request in the body of the response, which makes it easier for remote attackers to steal cookies and authentication credentials, or bypass the HttpOnly protection mechanism, by using TRACK to read the contents of the HTTP headers that are returned in the response, a technique that is similar to cross-site tracing (XST) using HTTP TRACE.

The (1) CertGetCertificateChain, (2) CertVerifyCertificateChainPolicy, and (3) WinVerifyTrust APIs within the CryptoAPI for Microsoft products including Microsoft Windows 98 through XP, Office for Mac, Internet Explorer for Mac, and Outlook Express for Mac, do not properly verify the Basic Constraints of intermediate CA-signed X.509 certificates, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack for SSL sessions, as originally reported for Internet Explorer and IIS.
