Microsoft Internet Explorer 3.0

Remote command execution in Microsoft Internet Explorer using .lnk and .url files.

Microsoft Internet Explorer before 8 uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack.

Microsoft Internet Explorer before 8 displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.

jscript.dll in Microsoft Internet Explorer 6.0 SP1 and earlier allows remote attackers to cause a denial of service (application crash) via a Shockwave Flash object that contains ActionScript code that calls VBScript, which in turn calls the Javascript document.write function, which triggers a null dereference.

Microsoft Internet Explorer 6.0.2900.2180 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption) via a long Unicode string argument to the write method, a related issue to CVE-2009-2479. NOTE: it was later reported that 7.0.6000.16473 and earlier are also affected.

Microsoft Internet Explorer 6.0.2900.2180 and earlier allows remote attackers to cause a denial of service (CPU consumption and application hang) via JavaScript code with a long string value for the hash property (aka location.hash), a related issue to CVE-2008-5715.

The JavaScript implementation in Microsoft Internet Explorer 8.0 and earlier does not properly restrict the set of values contained in the object returned by the getComputedStyle method, which allows remote attackers to obtain sensitive information about visited web pages by calling this method.

Microsoft Internet Explorer 9 and earlier does not properly restrict cross-zone drag-and-drop actions, which allows user-assisted remote attackers to read cookie files via vectors involving an IFRAME element with a SRC attribute containing an http: URL that redirects to a file: URL, as demonstrated by a Facebook game, related to a "cookiejacking" issue, aka "Drag and Drop Information Disclosure Vulnerability." NOTE: this vulnerability exists because of an incomplete fix in the Internet Explorer 9 release.

Microsoft Internet Explorer 8 and earlier, and Internet Explorer 9 beta, does not properly restrict cross-zone drag-and-drop actions, which allows user-assisted remote attackers to read cookie files via vectors involving an IFRAME element with a SRC attribute containing a file: URL, as demonstrated by a Facebook game, related to a "cookiejacking" issue.

The Cascading Style Sheets (CSS) implementation in Microsoft Internet Explorer 8.0 and earlier does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.

Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.3, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .html at the end of the query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character.

Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.5, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .shtml at the end of the query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1578 and CVE-2011-1587.

Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.4, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .html located before a ? (question mark) in a query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1578.

Cross-site scripting (XSS) vulnerability in Bugzilla 2.4 through 2.22.7, 3.0.x through 3.3.x, 3.4.x before 3.4.12, 3.5.x, 3.6.x before 3.6.6, 3.7.x, 4.0.x before 4.0.2, and 4.1.x before 4.1.3, when Internet Explorer before 9 or Safari before 5.0.6 is used for Raw Unified mode, allows remote attackers to inject arbitrary web script or HTML via a crafted patch, related to content sniffing.

Internet Explorer 5.0 and 5.01 allows remote attackers to bypass the cross frame security policy and read files via the external.NavigateAndFind function.

JavaScript in Internet Explorer 3.x and 4.x, and Netscape 2.x, 3.x and 4.x, allows remote attackers to monitor a user's web activities, aka the Bell Labs vulnerability.

Internet Explorer 3.x to 4.01 allows a remote attacker to insert malicious content into a frame of another web site, aka frame spoofing.

Internet Explorer 4.0 and 5.0 allows a malicious web site to obtain client cookies from another domain by including that domain name and escaped characters in a URL, aka the "Unauthorized Cookie Access" vulnerability.

By default, Internet Explorer 5.0 and other versions enables the "Navigate sub-frames across different domains" option, which allows frame spoofing.

Internet Explorer 3 records a history of all URL's that are visited by a user in DAT files located in the Temporary Internet Files and History folders, which are not cleared when the user selects the "Clear History" option, and are not visible when the user browses the folders because of tailored displays.
