Top vulnerabilities
CVE-2008-0075Unspecified vulnerability in Microsoft Internet Information Services (IIS) 5.1 through 6.0 allows remote attackers to execute arbitrary code via crafted inputs to ASP pages.
CVE-2001-0500Buffer 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.
CVE-1999-1376Buffer overflow in fpcount.exe in IIS 4.0 with FrontPage Server Extensions allows remote attackers to execute arbitrary commands.
CVE-1999-1011The 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.
CVE-1999-0874Buffer 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.
CVE-1999-0407By 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.
CVE-2009-3023Buffer overflow in the FTP Service in Microsoft Internet Information Services (IIS) 5.0 through 6.0 allows remote authenticated users to execute arbitrary code via a crafted NLST (NAME LIST) command that uses wildcards, leading to memory corruption, aka "IIS FTP Service RCE and DoS Vulnerability."
CVE-2010-1256Unspecified vulnerability in Microsoft IIS 6.0, 7.0, and 7.5, when Extended Protection for Authentication is enabled, allows remote authenticated users to execute arbitrary code via unknown vectors related to "token checking" that trigger memory corruption, aka "IIS Authentication Memory Corruption Vulnerability."
CVE-2007-0087Microsoft Internet Information Services (IIS), when accessed through a TCP connection with a large window size, allows remote attackers to cause a denial of service (network bandwidth consumption) via a Range header that specifies multiple copies of the same fragment. NOTE: the severity of this issue has been disputed by third parties, who state that the large window size required by the attack is not normally supported or configured by the server, or that a DDoS-style attack would accomplish the same goal
CVE-1999-0449The ExAir sample site in IIS 4 allows remote attackers to cause a denial of service (CPU consumption) via a direct request to the (1) advsearch.asp, (2) query.asp, or (3) search.asp scripts.
CVE-2007-2897Microsoft Internet Information Services (IIS) 6.0 allows remote attackers to cause a denial of service (server instability or device hang), and possibly obtain sensitive information (device communication traffic); and might allow attackers with physical access to execute arbitrary code after connecting a data stream to a device COM port; via requests for a URI containing a '/' immediately before and after the name of a DOS device, as demonstrated by the /AUX/.aspx URI, which bypasses a blacklist for DOS device requests.
CVE-2002-0869Unknown 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."
CVE-2002-0364Buffer 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."
CVE-2002-0150Buffer 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.
CVE-2002-0149Buffer overflow in ASP Server-Side Include Function in IIS 4.0, 5.0 and 5.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via long file names.
CVE-2002-0148Cross-site scripting vulnerability in Internet Information Server (IIS) 4.0, 5.0 and 5.1 allows remote attackers to execute arbitrary script as other users via an HTTP error page.
CVE-2002-0147Buffer overflow in the ASP data transfer mechanism in Internet Information Server (IIS) 4.0, 5.0, and 5.1 allows remote attackers to cause a denial of service or execute code, aka "Microsoft-discovered variant of Chunked Encoding buffer overrun."
CVE-2002-0079Buffer overflow in the chunked encoding transfer mechanism in Internet Information Server (IIS) 4.0 and 5.0 Active Server Pages allows attackers to cause a denial of service or execute arbitrary code.
CVE-2002-0075Cross-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.
CVE-2002-0074Cross-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.
CVE-2002-0071Buffer overflow in the ism.dll ISAPI extension that implements HTR scripting in Internet Information Server (IIS) 4.0 and 5.0 allows attackers to cause a denial of service or execute arbitrary code via HTR requests with long variable names.
CVE-2001-0334FTP service in IIS 5.0 and earlier allows remote attackers to cause a denial of service via a wildcard sequence that generates a long string when it is expanded.
CVE-2001-0333Directory traversal vulnerability in IIS 5.0 and earlier allows remote attackers to execute arbitrary commands by encoding .. (dot dot) and "\" characters twice.
CVE-2000-1104Variant 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.
CVE-2000-0970IIS 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.
