CVSS v3.1 |
| 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. |
| Microsoft Internet Information Services (IIS) server 4.0 SP4, without certain hotfixes released for SP4, does not require authentication credentials under certain conditions, which allows remote attackers to bypass authentication requirements, as demonstrated by connecting via Microsoft Visual InterDev 6.0. |
| 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. |
| Frontpage Server Extensions allows remote attackers to determine the name of the anonymous account via an RPC POST request to shtml.dll in the /_vti_bin/ virtual directory. |
| Sample Internet Data Query (IDQ) scripts in IIS 3 and 4 allow remote attackers to read files via a .. (dot dot) attack. |
| 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." |
| Vulnerability in Microsoft Windows NT 4.0 allows remote attackers to cause a denial of service in IIS by sending it a series of malformed requests which cause INETINFO.EXE to fail, aka the "Invalid URL" vulnerability. |
| Microsoft IIS for Far East editions 4.0 and 5.0 allows remote attackers to read source code for parsed pages via a malformed URL that uses the lead-byte of a double-byte character. |
| IIS 4.0 does not properly restrict access for the initial session request from a user's IP address if the address does not resolve to a DNS domain, aka the "Domain Resolution" vulnerability. |
| By default, IIS 4.0 has a virtual directory /IISADMPWD which contains files that can be used as proxies for brute force password attacks, or to identify valid users on the system. |
| The Microsoft MS00-060 patch for IIS 5.0 and earlier introduces an error which allows attackers to cause a denial of service via a malformed request. |
| FTP service in IIS 5.0 and earlier allows remote attackers to enumerate Guest accounts in trusted domains by preceding the username with a special sequence of characters. |
| 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 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 before, when installed on a FAT partition, allows a remote attacker to obtain source code of ASP files via a URL encoded with Unicode. |
| Cross-site scripting vulnerability in Help File search facility for Internet Information Server (IIS) 4.0, 5.0 and 5.1 allows remote attackers to embed scripts into another user's session. |
| 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. |
| 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. |
