Microsoft Internet Information Services 5.0

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 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.

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.

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."

Buffer overflow in the FTP Service in Microsoft Internet Information Services (IIS) 5.0 through 6.0 allows remote authenticated users to execute arbitrary code via a crafted NLST (NAME LIST) command that uses wildcards, leading to memory corruption, aka "IIS FTP Service RCE and DoS Vulnerability."

The WebDAV extension in Microsoft Internet Information Services (IIS) 5.0 on Windows 2000 SP4 does not properly decode URLs, which allows remote attackers to bypass authentication, and possibly read or create files, via a crafted HTTP request, aka "IIS 5.0 WebDAV Authentication Bypass Vulnerability," a different vulnerability than CVE-2009-1535.

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.

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.

Integer overflow in the Internet Printing Protocol (IPP) ISAPI extension in Microsoft Internet Information Services (IIS) 5.0 through 7.0 on Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, and Server 2008 allows remote authenticated users to execute arbitrary code via an HTTP POST request that triggers an outbound IPP connection from a web server to a machine operated by the attacker, aka "Integer Overflow in IPP Service Vulnerability."

Unspecified vulnerability in Microsoft Internet Information Services (IIS) 5.0 through 7.0 allows local users to gain privileges via unknown vectors related to file change notifications in the TPRoot, NNTPFile\Root, or WWWRoot folders.

The "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.

Microsoft Windows XP has weak permissions (FILE_WRITE_DATA and FILE_READ_DATA for Everyone) for %WINDIR%\pchealth\ERRORREP\QHEADLES, which allows local users to write and read files in this folder, as demonstrated by an ASP shell that has write access by IWAM_machine and read access by IUSR_Machine.

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 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.

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."

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 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.

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.

Buffer overflow in ssinc.dll for Microsoft Internet Information Services (IIS) 5.0 allows local users to execute arbitrary code via a web page with a Server Side Include (SSI) directive with a long filename, aka "Server Side Include Web Pages Buffer Overrun."

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.

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.

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.

Off-by-one error in the CodeBrws.asp sample script in Microsoft IIS 5.0 allows remote attackers to view the source code for files with extensions containing with one additional character after .html, .htm, .asp, or .inc, such as .aspx files.

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).

Cross-site scripting vulnerability (XSS) in the missing template handler in Macromedia ColdFusion MX allows remote attackers to execute arbitrary script as other users by injecting script into the HTTP request for the name of a template, which is not filtered in the resulting 404 error message.
