CVSS v3.1 |
| Buffer overflow in IIS 4.0 allows remote attackers to cause a denial of service via a malformed request for files with .HTR, .IDC, or .STM extensions. |
| 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. |
| Buffer overflow in fpcount.exe in IIS 4.0 with FrontPage Server Extensions allows remote attackers to execute arbitrary commands. |
| The Winmsdp.exe sample file in IIS 4.0 and Site Server 3.0 allows remote attackers to read arbitrary files. |
| 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. |
| When IIS 2 or 3 is upgraded to IIS 4, ism.dll is inadvertently left in /scripts/iisadmin, which does not restrict access to the local machine and allows an unauthorized user to gain access to sensitive server information, including the Administrator's password. |
| 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. |
| The Microsoft MS01-014 and MS01-016 patches for IIS 5.0 and earlier introduce a memory leak which allows attackers to cause a denial of service via a series of requests. |
| IIS does not properly canonicalize URLs, potentially allowing remote attackers to bypass access restrictions in third-party software via escape characters, aka the "Escape Character Parsing" vulnerability. |
| IIS 4.0 and Site Server 3.0 allow remote attackers to read source code for ASP files if the file is in a virtual directory whose name includes extensions such as .com, .exe, .sh, .cgi, or .dll, aka the "Virtual Directory Naming" vulnerability. |
| Sample Internet Data Query (IDQ) scripts in IIS 3 and 4 allow remote attackers to read files via a .. (dot dot) attack. |
| Norton Internet Security 2001 opens log files with FILE_SHARE_READ and FILE_SHARE_WRITE permissions, which could allow remote attackers to modify the log file contents while Norton Internet Security is running. |
| Buffer overflow in ISAPI extension (idq.dll) in Index Server 2.0 and Indexing Service 2000 in IIS 6.0 beta and earlier allows remote attackers to execute arbitrary commands via a long argument to Internet Data Administration (.ida) and Internet Data Query (.idq) files such as default.ida, as commonly exploited by Code Red. |
| IIS 4.0 allows attackers to cause a denial of service by requesting a large buffer in a POST or PUT command which consumes memory, aka the "Chunked Transfer Encoding Buffer Overflow Vulnerability." |
| IIS 4.0 with URL redirection enabled allows remote attackers to cause a denial of service (crash) via a malformed request that specifies a length that is different than the actual length. |
| 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 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. |
| Microsoft IIS 4.0 and before, when installed on a FAT partition, allows a remote attacker to obtain source code of ASP files via a URL encoded with Unicode. |
| 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. |
| 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. |
