Buffer overflow in ISAPI extension (idq.dll) in Index Server 2.0 and Indexing Service 2000 in IIS 6.0 beta and earlier allows remote attackers to execute arbitrary commands via a long argument to Internet Data Administration (.ida) and Internet Data Query (.idq) files such as default.ida, as commonly exploited by Code Red.
Buffer overflow in the ScStoragePathFromUrl function in the WebDAV service in Internet Information Services (IIS) 6.0 in Microsoft Windows Server 2003 R2 allows remote attackers to execute arbitrary code via a long header beginning with "If: <http://" in a PROPFIND request, as exploited in the wild in July or August 2016.
Unspecified vulnerability in Microsoft IIS 6.0, 7.0, and 7.5, when Extended Protection for Authentication is enabled, allows remote authenticated users to execute arbitrary code via unknown vectors related to "token checking" that trigger memory corruption, aka "IIS Authentication Memory Corruption Vulnerability."
Microsoft Internet Information Services (IIS) 6.0 allows remote attackers to cause a denial of service (server instability or device hang), and possibly obtain sensitive information (device communication traffic); and might allow attackers with physical access to execute arbitrary code after connecting a data stream to a device COM port; via requests for a URI containing a '/' immediately before and after the name of a DOS device, as demonstrated by the /AUX/.aspx URI, which bypasses a blacklist for DOS device requests.
Buffer overflow in Microsoft Internet Information Services (IIS) 5.0, 5.1, and 6.0 allows local and possibly remote attackers to execute arbitrary code via crafted Active Server Pages (ASP).
Microsoft IIS 5.1 and 6 allows remote attackers to spoof the SERVERNAME variable to bypass security checks and conduct various attacks via a GET request with an http://localhost URI, which makes it appear as if the request is coming from localhost.
The WebDAV Message Handler for Internet Information Services (IIS) 5.0, 5.1, and 6.0 allows remote attackers to cause a denial of service (memory and CPU exhaustion, application crash) via a PROPFIND request with an XML message containing XML elements with a large number of attributes.
Microsoft IIS 5.0 and 6.0 allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a "Transfer-Encoding: chunked" header and a Content-Length header, which causes IIS to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka "HTTP Request Smuggling."
Unspecified vulnerability in the IIS connector in Adobe JRun 4.0 Updater 6, and ColdFusion MX 6.1 and 7.0 Enterprise, when using Microsoft IIS 6, allows remote attackers to cause a denial of service via unspecified vectors, involving the request of a file in the JRun web root.
Microsoft Internet Information Services (IIS) 6.0, when DNS resolution is enabled for client IP addresses, allows remote attackers to inject arbitrary text into log files via an HTTP request in conjunction with a crafted DNS response, as demonstrated by injecting XSS sequences, related to an "Inverse Lookup Log Corruption (ILLC)" issue.
