Microsoft Internet Information 5.0

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.

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."

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.

ISM.DLL in IIS 4.0 and 5.0 allows remote attackers to read file contents by requesting the file and appending a large number of encoded spaces (%20) and terminated with a .htr extension, aka the ".HTR File Fragment Reading" or "File Fragment Reading via .HTR" vulnerability.

Buffer overflow in Internet Information Server (IIS) 4.0, 5.0, and 5.1 allows remote attackers to spoof the safety check for HTTP headers and cause a denial of service or execute arbitrary code via HTTP header field values.

IIS 4.0 and 5.0 .ASP pages send the same Session ID cookie for secure and insecure web sessions, which could allow remote attackers to hijack the secure web session of the user if that user moves to an insecure session, aka the "Session ID Cookie Marking" vulnerability.

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.

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 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.

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 4.0 and 5.0 allows remote attackers to cause a denial of service by sending many URLs with a large number of escaped characters, aka the "Myriad Escaped Characters" Vulnerability.

In IIS, an attacker could determine a real path using a request for a non-existent URL that would be interpreted by Perl (perl.exe).

Microsoft IIS 5.0 allows remote attackers to spoof web log entries via an HTTP request that includes hex-encoded newline or form-feed characters.

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.

Vulnerabilities in IIS 4.0 and 5.0 do not properly protect against cross-site scripting (CSS) attacks. They allow a malicious web site operator to embed scripts in a link to a trusted site, which are returned without quoting in an error message back to the client. The client then executes those scripts in the same context as the trusted site, aka the "IIS Cross-Site Scripting" vulnerabilities.

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."

Variant of the "IIS Cross-Site Scripting" vulnerability as originally discussed in MS:MS00-060 (CVE-2000-0746) allows a malicious web site operator to embed scripts in a link to a trusted site, which are returned without quoting in an error message back to the client. The client then executes those scripts in the same context as the trusted site.

Buffer overflow in ssinc.dll in IIS 5.0 and 4.0 allows local users to gain system privileges via a Server-Side Includes (SSI) directive for a long filename, which triggers the overflow when the directory name is added, aka the "SSI privilege elevation" vulnerability.

IIS 5.0 uses relative paths to find system files that will run in-process, which allows local users to gain privileges via a Trojan horse file, aka the "System file listing privilege elevation" 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.

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.

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.

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.

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.

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.
