| CVE-2011-5279
|

|
| CVE-2009-4445
|
6.0Microsoft Internet Information Services (IIS), when used in conjunction with unspecified third-party upload applications, allows remote attackers to create empty files with arbitrary extensions via a filename containing an initial extension followed by a : (colon) and a safe extension, as demonstrated by an upload of a .asp:.jpg file that results in creation of an empty .asp file, related to support for the NTFS Alternate Data Streams (ADS) filename syntax. NOTE: it could be argued that this is a vulnerability in the third-party product, not IIS, because the third-party product should be applying its extension restrictions to the portion of the filename before the colon.
|
| CVE-2009-4444
|
6.0Microsoft Internet Information Services (IIS) 5.x and 6.x uses only the portion of a filename before a ; (semicolon) character to determine the file extension, which allows remote attackers to bypass intended extension restrictions of third-party upload applications via a filename with a (1) .asp, (2) .cer, or (3) .asa first extension, followed by a semicolon and a safe extension, as demonstrated by the use of asp.dll to handle a .asp;.jpg file.
|
| CVE-2009-2521
|

|
| CVE-2007-2815
|
10.0The "hit-highlighting" functionality in webhits.dll in Microsoft Internet Information Services (IIS) Web Server 5.0 only uses Windows NT ACL configuration, which allows remote attackers to bypass NTLM and basic authentication mechanisms and access private web directories via the CiWebhitsfile parameter to null.htw.
|
| CVE-2006-0026
|

|
| CVE-2005-2089
|
4.3Microsoft 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."
|
| CVE-2003-1567
|
5.8The 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.

|
| CVE-2002-1695
|

|
| CVE-2002-1694
|
5.0Microsoft Internet Information Server (IIS) 4.0 opens log files with FILE_SHARE_READ and FILE_SHARE_WRITE permissions, which could allow remote attackers to modify the log file contents while IIS is running.

|
| CVE-2002-1180
|

|
| CVE-2002-0422
|
2.6IIS 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.
|
| CVE-2002-0419
|
5.0Information leaks in IIS 4 through 5.1 allow remote attackers to obtain potentially sensitive information or more easily conduct brute force attacks via responses from the server in which (2) in certain configurations, the server IP address is provided as the realm for Basic authentication, which could reveal real IP addresses that were obscured by NAT, or (3) when NTLM authentication is used, the NetBIOS name of the server and its Windows NT domain are revealed in response to an Authorization request. NOTE: this entry originally contained a vector (1) in which the server reveals whether it supports Basic or NTLM authentication through 401 Access Denied error messages. CVE has REJECTED this vector; it is not a vulnerability because the information is already available through legitimate use, since authentication cannot proceed without specifying a scheme that is supported by both the client and the server.
