Microsoft Internet Information

Cross-site scripting vulnerability (XSS) in the ASP function responsible for redirection in Microsoft Internet Information Server (IIS) 4.0, 5.0, and 5.1 allows remote attackers to embed a URL containing script in a redirection message.

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 .NET Framework 1.1 SP1, 2.0 SP1 and SP2, 3.5, 3.5 SP1, 3.5.1, and 4.0, as used for ASP.NET in Microsoft Internet Information Services (IIS), provides detailed error codes during decryption attempts, which allows remote attackers to decrypt and modify encrypted View State (aka __VIEWSTATE) form data, and possibly forge cookies or read application files, via a padding oracle attack, aka "ASP.NET Padding Oracle Vulnerability."

IIS 4.0 and 5.0 does not properly restrict access to certain types of files when their parent folders have less restrictive permissions, which could allow remote attackers to bypass access restrictions to some files, aka the "File Permission Canonicalization" vulnerability.

Microsoft 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.

Microsoft 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.

The IP Security feature in Microsoft Internet Information Services (IIS) 8.0 and 8.5 does not properly process wildcard allow and deny rules for domains within the "IP Address and Domain Restrictions" list, which makes it easier for remote attackers to bypass an intended rule set via an HTTP request, aka "IIS Security Feature Bypass Vulnerability."

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.

IIS 5.0 allows remote attackers to obtain source code for .ASP files and other scripts via an HTTP GET request with a "Translate: f" header, aka the "Specialized Header" vulnerability.

Stack consumption vulnerability in the FTP Service in Microsoft Internet Information Services (IIS) 5.0 through 7.0 allows remote authenticated users to cause a denial of service (daemon crash) via a list (ls) -R command containing a wildcard that references a subdirectory, followed by a .. (dot dot), aka "IIS FTP Service DoS Vulnerability."

IIS 4.0 and 5.0 does not properly perform ISAPI extension processing if a virtual directory is mapped to a UNC share, which allows remote attackers to read the source code of ASP and other files, aka the "Virtualized UNC Share" vulnerability.

Scripting.FileSystemObject in asp.dll for Microsoft IIS 4.0 and 5.0 allows local or remote attackers to cause a denial of service (crash) via (1) creating an ASP program that uses Scripting.FileSystemObject to open a file with an MS-DOS device name, or (2) remotely injecting the device name into ASP programs that internally use Scripting.FileSystemObject.

IIS 4.0 and 5.0 allows remote attackers to obtain fragments of source code by appending a +.htr to the URL, a variant of the "File Fragment Reading via .HTR" vulnerability.

IIS 5.0 allows remote attackers to cause a denial of service via a series of malformed WebDAV requests.

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).

IIS 4.05 and 5.0 allow remote attackers to cause a denial of service via a long, complex URL that appears to contain a large number of file extensions, aka the "Malformed Extension Data in URL" vulnerability.

The w3svc.dll ISAPI filter in Front Page Server Extensions and ASP.NET for Internet Information Server (IIS) 4.0, 5.0, and 5.1 does not properly handle the error condition when a long URL is provided, which allows remote attackers to cause a denial of service (crash) when the URL parser accesses a null pointer.

The FTP service in Internet Information Server (IIS) 4.0, 5.0 and 5.1 allows attackers who have established an FTP session to cause a denial of service via a specially crafted status request containing glob characters.

A misconfiguration in IIS 5.0 with Index Server enabled and the Index property set allows remote attackers to list directories in the web root via a Web Distributed Authoring and Versioning (WebDAV) search.

The shtml.exe program in the FrontPage extensions package of IIS 4.0 and 5.0 allows remote attackers to determine the physical path of HTML, HTM, ASP, and SHTML files by requesting a file that does not exist, which generates an error message that reveals the path.

Microsoft Internet Information Services (IIS) 5.0 and 5.1 allows remote attackers to cause a denial of service via a long WebDAV request with a (1) PROPFIND or (2) SEARCH method, which generates an error condition that is not properly handled.

Microsoft IIS 5.1 and 6 allows remote attackers to spoof the SERVER_NAME 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.

IIS 2.0 and 3.0 allows remote attackers to read the source code for ASP pages by appending a . (dot) to the end of the URL.

The ASP function Response.AddHeader in Microsoft Internet Information Server (IIS) 4.0 and 5.0 does not limit memory requests when constructing headers, which allow remote attackers to generate a large header to cause a denial of service (memory consumption) with an ASP page.

Information 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.

IIS 5.0 and Microsoft Exchange 2000 allow remote attackers to cause a denial of service (memory allocation error) by repeatedly sending a series of specially formatted URL's.

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.

Microsoft IIS 5.0 allows remote attackers to cause a denial of service via an HTTP request with a content-length value that is larger than the size of the request, which prevents IIS from timing out the connection.

The SMTP service in Microsoft Internet Information Services (IIS) 4.0 and 5.0 allows remote attackers to bypass anti-relaying rules and send spam or spoofed messages via encapsulated SMTP addresses, a similar vulnerability to CVE-1999-0682.

Microsoft IIS 4.0 and 5.0 with the IISADMPWD virtual directory installed allows a remote attacker to cause a denial of service via a malformed request to the inetinfo.exe program, aka the "Undelimited .HTR Request" vulnerability.

IIS 5.0 and 4.0 allows remote attackers to read the source code for executable web server programs by appending "%3F+.htr" to the requested URL, which causes the files to be parsed by the .HTR ISAPI extension, aka a variant of the "File Fragment Reading via .HTR" vulnerability.

Microsoft Internet Information Services (IIS) 5.0 does not log requests that use the TRACK method, which allows remote attackers to obtain sensitive information without detection.

IIS 4.0 allows a remote attacker to obtain the real pathname of the document root by requesting non-existent files with .ida or .idq extensions.

Vulnerability in IIS 5.0 allows remote attackers to cause a denial of service (restart) via a long, invalid WebDAV request.

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.

An administrative script from IIS 3.0, later included in IIS 4.0 and 5.0, allows remote attackers to cause a denial of service by accessing the script without a particular argument, aka the "Absent Directory Browser Argument" vulnerability.

FrontPage Server Extensions (FPSE) in IIS 4.0 and 5.0 allows remote attackers to cause a denial of service via a malformed form, aka the "Malformed Web Form Submission" vulnerability.

CRLF injection vulnerability in the CGI implementation in Microsoft Internet Information Services (IIS) 4.x and 5.x on Windows NT and Windows 2000 allows remote attackers to modify arbitrary uppercase environment variables via a \n (newline) character in an HTTP header.

Microsoft Internet Information Server (IIS) 5.1 allows remote attackers to view path information via a GET request to (1) /_vti_pvt/access.cnf, (2) /_vti_pvt/botinfs.cnf, (3) /_vti_pvt/bots.cnf, or (4) /_vti_pvt/linkinfo.cnf.

Microsoft Internet Information Server (IIS) 5.1 may allow remote attackers to view the contents of a Frontpage Server Extension (FPSE) file, as claimed using an HTTP request for colegal.htm that contains .. (dot dot) sequences.
