Buffer Overflow
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Buffer overflow in the ScStoragePathFromUrl function in the WebDAV service in Internet Information Services (IIS) 6.0 in Microsoft Windows Server 2003 R2 allows remote attackers to execute arbitrary code via a long header beginning with "If: <http://" in a PROPFIND request, as exploited in the wild in July or August 2016.

AV:N/AC:H/Au:N/C:P/I:P/A:P

The IP Security feature in Microsoft Internet Information Services (IIS) 8.0 and 8.5 does not properly process wildcard allow and deny rules for domains within the "IP Address and Domain Restrictions" list, which makes it easier for remote attackers to bypass an intended rule set via an HTTP request, aka "IIS Security Feature Bypass Vulnerability."

CRLF Injection
AV:N/AC:L/Au:N/C:N/I:P/A:N

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.

XSS
AV:N/AC:M/Au:N/C:N/I:P/A:N

Cross-site scripting (XSS) vulnerability in EMC RSA Authentication Agent 7.1 before 7.1.1 for Web for Internet Information Services, and 7.1 before 7.1.1 for Web for Apache, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

First published (updated )
Severity
2.1
AV:L/AC:L/Au:N/C:P/I:N/A:N

EMC RSA Authentication API before 8.1 SP1, RSA Web Agent before 5.3.5 for Apache Web Server, RSA Web Agent before 5.3.5 for IIS, RSA PAM Agent before 7.0, and RSA Agent before 6.1.4 for Microsoft Windows use an improper encryption algorithm and a weak key for maintaining the stored data of the node secret for the SecurID Authentication API, which allows local users to obtain sensitive information via cryptographic attacks on this data.

Buffer Overflow
AV:N/AC:L/Au:N/C:C/I:C/A:C

Heap-based buffer overflow in the TELNETSTREAMCONTEXT::OnSendData function in ftpsvc.dll in Microsoft FTP Service 7.0 and 7.5 for Internet Information Services (IIS) 7.0, and IIS 7.5, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a crafted FTP command, aka "IIS FTP Service Heap Buffer Overrun Vulnerability." NOTE: some of these details are obtained from third party information.

AV:N/AC:L/Au:N/C:P/I:P/A:N

Microsoft .NET Framework 1.1 SP1, 2.0 SP1 and SP2, 3.5, 3.5 SP1, 3.5.1, and 4.0, as used for ASP.NET in Microsoft Internet Information Services (IIS), provides detailed error codes during decryption attempts, which allows remote attackers to decrypt and modify encrypted View State (aka VIEWSTATE) form data, and possibly forge cookies or read application files, via a padding oracle attack, aka "ASP.NET Padding Oracle Vulnerability."

Buffer Overflow
AV:N/AC:M/Au:N/C:N/I:N/A:P

Stack consumption vulnerability in the ASP implementation in Microsoft Internet Information Services (IIS) 5.1, 6.0, 7.0, and 7.5 allows remote attackers to cause a denial of service (daemon outage) via a crafted request, related to asp.dll, aka "IIS Repeated Parameter Request Denial of Service Vulnerability."

Buffer Overflow
AV:N/AC:M/Au:N/C:C/I:C/A:C

Buffer overflow in Microsoft Internet Information Services (IIS) 7.5, when FastCGI is enabled, allows remote attackers to execute arbitrary code via crafted headers in a request, aka "Request Header Buffer Overflow Vulnerability."

AV:N/AC:M/Au:S/C:P/I:P/A:P

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.

AV:N/AC:L/Au:N/C:N/I:N/A:P

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."

AV:N/AC:L/Au:N/C:P/I:P/A:P

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.

First published (updated )
Severity
7.5
AV:N/AC:L/Au:N/C:P/I:P/A:P

The WebDAV extension in Microsoft Internet Information Services (IIS) 5.1 and 6.0 allows remote attackers to bypass URI-based protection mechanisms, and list folders or read, create, or modify files, via a %c0%af (Unicode / character) at an arbitrary position in the URI, as demonstrated by inserting %c0%af into a "/protected/" initial pathname component to bypass the password protection on the protected\ folder, aka "IIS 5.1 and 6.0 WebDAV Authentication Bypass Vulnerability," a different vulnerability than CVE-2009-1122.

AV:N/AC:L/Au:N/C:N/I:P/A:N

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.

Infoleak
AV:N/AC:M/Au:N/C:P/I:P/A:N

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.

AV:L/AC:L/Au:N/C:C/I:C/A:C

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.

AV:N/AC:L/Au:N/C:C/I:C/A:C

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.

Infoleak
AV:N/AC:L/Au:N/C:P/I:N/A:N

Adobe ColdFusion MX 7 through 7.0.2, and JRun 4, when run on Microsoft IIS, allows remote attackers to read arbitrary files, list directories, or read source code via a double URL-encoded NULL byte in a ColdFusion filename, such as a CFM file.

AV:N/AC:L/Au:N/C:P/I:P/A:P

Microsoft Internet Information Services (IIS) 5.1 permits the IUSRMachine account to execute non-EXE files such as .COM files, which allows attackers to execute arbitrary commands via arguments to any .COM file that executes those arguments, as demonstrated using win.com when it is in a web directory with certain permissions.

AV:L/AC:M/Au:N/C:P/I:P/A:P

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.
