As part of this processing, IIS checks for delimiters that are supposed to mark boundaries within the headers. By constructing a carefully chosen HTTP request, and intruder to cause IIS to incorrectly parse an HTTP header, and place the incorrect results into a buffer that is too small. For more information, see [Microsoft Security Bulletin MS02-018](<http://www.microsoft.com/technet/security/bulletin/ms02-018.asp>). \n \n--- \n \n### Impact \n\nAn intruder can interrupt the ordinary operation of a vulnerable IIS server or execute arbitrary code with the privileges of ASP ISAPI extension, ASP.DLL. On IIS 4.0, ASP.DLL runs as part of the operating system thus allowing an intruder to take full administrative control. On IIS 5.0 and 5.1, ASP.DLL runs with the privileges of the IWAM__computername_ account. \n \n--- \n \n### Solution \n\nApply a patch as described in [Microsoft Security Bulletin MS02-018](<http://www.microsoft.com/technet/security/bulletin/ms02-018.asp>). \n \n--- \n \nUntil a patch can be applied, you may wish to disable the ASP ISAPI extension by using the IIS Lockdown tool, available at <http://www.microsoft.com/technet/security/tools/locktool.asp>.

Microsoft&#39;s bulletin is available at\r\n\r\n http://www.microsoft.com/technet/security/bulletin/MS02-018.asp\r\n\r\n Additional information about these vulnerabilities is available at\r\n\r\n http://www.kb.cert.org/vuls\r\n\r\n\r\n VU#363715 CAN-2002-0071 Microsoft Internet Information Server &#40;IIS&#41;\r\n vulnerable to heap overflow during processing of crafted\r\n &quot;.htr&quot; request by &quot;ISM.DLL&quot; ISAPI filter\r\n\r\n VU#883091 CAN-2002-0074 Microsoft Internet Information Server &#40;IIS&#41;\r\n contains cross-site scripting vulnerability in IIS Help\r\n Files search facility\r\n\r\n VU#886699 CAN-2002-0148 Microsoft Internet Information Server &#40;IIS&#41;\r\n contains cross-site scripting vulnerability in HTTP error\r\n page results\r\n\r\n VU#520707 CAN-2002-0075 Microsoft Internet Information Server &#40;IIS&#41;\r\n contains cross-site scripting vulnerability in redirect\r\n response messages\r\n\r\n VU#412203 CAN-2002-0073 Microsoft Internet Information Server &#40;IIS&#41;\r\n vulnerable to DoS via malformed FTP connection status\r\n request\r\n\r\n VU#454091 CAN-2002-0150 Microsoft Internet Information Server &#40;IIS&#41;\r\n vulnerable to buffer overflow via inaccurate checking of\r\n delimiters in HTTP header fields\r\n\r\n VU#721963 CAN-2002-0149 Microsoft Internet Information Server &#40;IIS&#41;\r\n buffer overflow in server-side includes &#40;SSI&#41; containing\r\n long invalid file name\r\n\r\n VU#521059 CAN-2002-0072 Microsoft Internet Information Server &#40;IIS&#41;\r\n vulnerable to DoS when URL request exceeds maximum\r\n allowed length\r\n\r\n VU#610291 CAN-2002-0079 Microsoft Internet Information Server &#40;IIS&#41;\r\n buffer overflow in chunked encoding transfer mechanism\r\n\r\n VU#669779 CAN-2002-0147 Microsoft Internet Information Server &#40;IIS&#41;\r\n buffer overflow in chunked encoding transfer mechanism\r\n\r\n\r\nII. Impact\r\n\r\n For many of the vulnerabilities, an intruder could execute arbitrary\r\n code with privileges that vary according to which version of IIS is\r\n running. In general, IIS 4.0 permits an intruder to execute code with\r\n complete administrative privileges, while IIS 5.0 and 5.1 permit an\r\n intruder to execute code with the privileges of the IWAM_computername\r\n account.\r\n\r\nIII. Solution\r\n\r\n Microsoft Corporation has released Microsoft Security Bulletin\r\n MS02-018, which announces the availability of a cumulative patch to\r\n address a variety of problems. We strongly encourage you to read this\r\n bulletin and take the appropriate corrective measures. MS02-018 is\r\n available at\r\n\r\n http://www.microsoft.com/technet/security/bulletin/MS02-018.asp\r\n\r\n In addition to applying the patch, or until it can be applied, we\r\n recommend the following actions:\r\n\r\n * Use the IIS Lockdown tool and URLScan to eliminate or reduce the\r\n impact of some of these vulnerabilites; they may also eliminate or\r\n reduce other vulnerabilities that have not yet been discovered.\r\n The IIS Lockdown tool can also be used to disable ASP if it&#39;s not\r\n needed. More information about the IIS Lockdown tool and URLScan\r\n can be found at\r\n\r\n http://www.microsoft.com/technet/security/tools/locktool.asp\r\n \r\n http://www.microsoft.com/technet/security/URLScan.asp\r\n\r\n * As Microsoft has recommended for quite some time, disable the HTR\r\n ISAPI extension unless it is absolutely required.\r\n * Disable anonymous FTP unless it is required.\r\n * Don&#39;t give login credentials on IIS servers to untrusted users.\r\n _________________________________________________________________\r\n\r\n Our thanks to Microsoft Corporation for the information contained in\r\n their advisory.

These vulnerabilities\r\nvary in severity from mild to critical. A remote attacker may exploit\r\none or more of these vulnerabilities to cause a target Web server to\r\ncrash, execute arbitrary commands on the server, or gain complete\r\ncontrol of a target IIS server.\r\n\r\nAffected Versions:\r\n\r\nMicrosoft Internet Information Server 4.0\r\nMicrosoft Internet Information Server 5.0\r\nMicrosoft Internet Information Server 5.1\r\n\r\nNote: IIS 6.0 Beta build 3605 and earlier are also affected.\r\n\r\nDescription:\r\n\r\nMicrosoft released a Security Bulletin on April 10, 2002 detailing new\r\ncumulative patches for IIS 4.0, 5.0, and 5.1. These patches contain all\r\nprevious security patches for each version as well as patches for ten\r\nnew vulnerabilities.\r\n\r\nHeap Buffer overflow in ASP chunked encoding routines\r\n&#40;CAN-2002-0079&#41;\r\n\r\nASP &#40;Active Server Pages&#41; is enabled on all IIS installations by\r\ndefault. ASP is used to dynamically generate HTML pages on the server\r\nand deliver them to a client. IIS improperly handles specially-crafted\r\nchunked encoding queries to ASP pages. Chunked encoding is used in\r\nsituations when a client supplies the server with a variable amount of\r\ninformation. If the client supplies data using chunked encoding, the\r\nserver dynamically allocates memory according to the size of each\r\nincoming chunk. IIS improperly adds the sizes of these allocated chunks,\r\nwhich may overwrite memory. Successful exploitation of this\r\nvulnerability may crash a vulnerable server, allowing remote attackers\r\nto execute arbitrary commands on the server with IWAM_computername\r\nprivileges. This account is equivalent to an unprivileged normal user.\r\nThis vulnerability affects IIS versions 4.0 and 5.0.\r\n\r\nBuffer overflow within the ASP data transfer mechanism\r\n&#40;CAN-2002-0147&#41;\r\n\r\nThis vulnerability is similar to the previous vulnerability and affects\r\nIIS versions 4.0, 5.0, and 5.1.\r\n\r\nBuffer overflow in IIS HTTP header delimiter parsing\r\n&#40;CAN-2002-0150&#41;\r\n\r\nIt may be possible for remote attackers to create a special request to\r\nbypass IIS delimiter parsing. IIS 4.0, 5.0, and 5.1 may incorrectly\r\nparse this request and overflow a buffer, which may lead to a denial of\r\nservice attack or the ability to execute arbitrary code on the target\r\nserver with IWAM_computername privileges.\r\n\r\nBuffer overflow in IIS ASP Server-Side Include routines\r\n&#40;CAN-2002-0149&#41;\r\n\r\nASP scripts sometimes process external files in order to function\r\ncorrectly. If an attacker sends a specific query to an overly long\r\nfilename, this name may be processed within the ASP script as a server-\r\nside include &#40;SSI&#41;. A buffer overflow may be triggered if the length of\r\nthe filename is longer than the static buffer within the SSI routine.\r\nThis vulnerability affects IIS 4.0, 5.0, and 5.1. Successful\r\nexploitation of this vulnerability may crash the server or allow an\r\nattacker to execute arbitrary code on the target server with\r\nIWAM_computername privileges.\r\n\r\n\r\nBuffer overflow in the HTR ISAPI extension\r\n&#40;CAN-2002-0071&#41;\r\n\r\nHTR was the predecessor to ASP and is considered a legacy technology.\r\nHTR remains in use today to handle password management in IIS. It may be\r\npossible for an attacker to send a malformed HTR request to a vulnerable\r\nIIS 4.0 or 5.0 server to cause a denial of service attack. An attacker\r\nmay also use this vulnerability to run arbitrary commands with\r\nIWAM_computername privileges. HTR files need not be present on the\r\nserver for attackers to exploit this vulnerability.\r\n\r\nDenial of service caused by improper handling of error conditions in\r\nISAPI filters\r\n&#40;CAN-2002-0072&#41;\r\n\r\nIf vulnerable ISAPI filters within IIS 4.0, 5.0, and 5.1 receive a URL\r\nof an illegal length, IIS will improperly rewrite the URL with a null\r\nvalue and attempt to send the error back to the client that requested\r\nthe URL. Before the request is sent, IIS attempts to operate on the null\r\nvalue, which causes a fault that crashes the server.\r\n\r\nDenial of service in the IIS 4.0, 5.0 and 5.1 FTP &#40;File Transfer\r\nProtocol&#41; service\r\n&#40;CAN-2002-0073&#41;\r\n\r\nIIS improperly handles specially-crafted status requests on current FTP\r\nsessions. When an attacker sends this type of request to an IIS server,\r\nit may lead to improper access of uninitialized memory, which may result\r\nin a denial of service to FTP and Web services.\r\n\r\nCross-Site Scripting &#40;CSS&#41; vulnerabilities present in IIS 4.0, 5.0 and\r\n5.1\r\n&#40;CAN-2002-0074&#41;\r\n&#40;CAN-2002-0148&#41;\r\n&#40;CAN-2002-0075&#41;\r\n\r\nCSS vulnerabilities rely on the ability of an attacker to lure users to\r\ntheir rogue Web servers. When a user visits a specific page on a rogue\r\nWeb server, the request for the URL is relayed to a third-party site\r\nusing active scripting. If this third-party site is trusted by the user,\r\nthe attacker\u2019s Web site is trusted just like the third-party site,\r\ninheriting that the same level of privilege. IIS contains CSS\r\nvulnerabilities when searching IIS help files, viewing HTTP error pages,\r\nand notifying a user when a request has been redirected.\r\n\r\nRecommendations:\r\n\r\nX-Force recommends that all affected IIS customers apply the following\r\nMicrosoft supplied patches immediately:\r\n\r\nMicrosoft IIS 4.0:\r\nhttp://www.microsoft.com/Downloads/Release.asp?ReleaseID=37931\r\nMicrosoft IIS 5.0:\r\nhttp://www.microsoft.com/Downloads/Release.asp?ReleaseID=37824\r\nMicrosoft IIS 5.1:\r\nhttp://www.microsoft.com/Downloads/Release.asp?ReleaseID=37857\r\n\r\nRealSecure Network Sensor may trigger several signatures in response to\r\nthe IIS attacks described in this advisory.
