The Remote Data Service (RDS) DataFactory component of Microsoft Data Access Components (MDAC) in IIS 3.x and 4.x exposes unsafe methods, which allows remote attackers to execute arbitrary commands.
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).
In IIS and other web servers, an attacker can attack commands as SYSTEM if the server is running as SYSTEM and loading an ISAPI extension.
A buffer overflow in the FTP list (ls) command in IIS allows remote attackers to conduct a denial of service and, in some cases, execute arbitrary commands.
IIS 3.0 with the iis-fix hotfix installed allows remote intruders to read source code for ASP programs by using a %2e instead of a . (dot) in the URL.
When IIS is run with a default language of Chinese, Korean, or Japanese, it allows a remote attacker to view the source code of certain files, a.k.a. "Double Byte Code Page".
IIS newdsn.exe CGI script allows remote users to overwrite files.
Trend Micro Virus Control System (TVCS) 1.8 running with IIS allows remote attackers to cause a denial of service (memory consumption) in IIS via multiple URL requests for ActiveSupport.exe.
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.
Sample Internet Data Query (IDQ) scripts in IIS 3 and 4 allow remote attackers to read files via a .. (dot dot) attack.
Frontpage Server Extensions allows remote attackers to determine the name of the anonymous account via an RPC POST request to shtml.dll in the /vtibin/ virtual directory.
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.
Buffer overflow in FTP server in Microsoft IIS 3.0 and 4.0 allows local and sometimes remote attackers to cause a denial of service via a long NLST (ls) command.
IIS 3.x and 4.x does not distinguish between pages requiring encryption and those that do not, which allows remote attackers to cause a denial of service (resource exhaustion) via SSL requests to the HTTPS port for normally unencrypted files, which will cause IIS to perform extra work to send the files over SSL.
The Sun HotSpot Performance Engine VM allows a remote attacker to cause a denial of service on any server running HotSpot via a URL that includes the [ character.
FileSystemObject (FSO) in the showfile.asp Active Server Page (ASP) allows remote attackers to read arbitrary files by specifying the name in the file parameter.
IIS 3.0 allows remote attackers to cause a denial of service via a request to an ASP page in which the URL contains a large number of / (forward slash) characters.
IIS 3.0 and 4.0 on x86 and Alpha allows remote attackers to cause a denial of service (hang) via a malformed GET request, aka the IIS "GET" vulnerability.
Denial of service in IIS using long URLs.
In IIS, remote attackers can obtain source code for ASP files by appending "::$DATA" to the URL.
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.
Information from SSL-encrypted sessions via PKCS #1.
Microsoft Windows XP has weak permissions (FILEWRITEDATA and FILEREADDATA 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 IWAMmachine and read access by IUSRMachine.
IIS 4.0 allows remote attackers to obtain the internal IP address of the server via an HTTP 1.0 request for a web page which is protected by basic authentication and has no realm defined.
