Directory traversal vulnerability in CodeBrws.asp in Microsoft IIS 5.0 allows remote attackers to view source code and determine the existence of arbitrary files via a hex-encoded "%c0%ae%c0%ae" string, which is the Unicode representation for ".." (dot dot).

Microsoft IIS 5.0 and 5.1 allows remote attackers to cause a denial of service (CPU consumption) via an HTTP request with a Host header that contains a large number of "/" (forward slash) characters.

Multiple cross-site scripting (XSS) vulnerabilities in the administrative web pages for Microsoft Internet Information Server (IIS) 4.0 through 5.1 allow remote attackers to execute HTML script as other users through (1) a certain ASP file in the IISHELP virtual directory, or (2) possibly other unknown attack vectors.

A typographical error in the script source access permissions for Internet Information Server (IIS) 5.0 does not properly exclude .COM files, which allows attackers with only write permissions to upload malicious .COM files, aka "Script Source Access Vulnerability."

IIS 5.0 and 5.1 allows remote attackers to cause a denial of service (crash) via malformed WebDAV requests that cause a large amount of memory to be assigned.

Unknown vulnerability in the hosting process (dllhost.exe) for Microsoft Internet Information Server (IIS) 4.0 through 5.1 allows remote attackers to gain privileges by executing an out of process application that acquires LocalSystem privileges, aka "Out of Process Privilege Elevation."

IIS 5 and 5.1 supporting WebDAV methods allows remote attackers to determine the internal IP address of the system (which may be obscured by NAT) via (1) a PROPFIND HTTP request with a blank Host header, which leaks the address in an HREF property in a 207 Multi-Status response, or (2) via the WRITE or MKCOL method, which leaks the IP in the Location server header.

Buffer overflow in the chunked encoding transfer mechanism in IIS 4.0 and 5.0 allows attackers to execute arbitrary code via the processing of HTR request sessions, aka "Heap Overrun in HTR Chunked Encoding Could Enable Web Server Compromise."

The MSDTC (Microsoft Distributed Transaction Service Coordinator) for Microsoft Windows 2000, Microsoft IIS 5.0 and SQL Server 6.5 through SQL 2000 0.0 allows remote attackers to cause a denial of service (crash or hang) via malformed (random) input.

Cross-site scripting vulnerability for Internet Information Server (IIS) 4.0, 5.0 and 5.1 allows remote attackers to execute arbitrary script as other web users via the error message used in a URL redirect (""302 Object Moved") message.
