Microsoft » Internet Explorer : Security Vulnerabilities, CVEs, (Bypass)

Microsoft Internet Explorer 11 and Microsoft Edge allow remote attackers to conduct content-spoofing attacks via a crafted URL, aka "Microsoft Browser Spoofing Vulnerability."

Microsoft Internet Explorer 9 through 11 and Microsoft Edge allow remote attackers to conduct content-spoofing attacks via a crafted URL, aka "Microsoft Browser Spoofing Vulnerability."

Microsoft Internet Explorer 9 through 11 allows remote attackers to trick users into making TCP connections to a restricted port via a crafted web site, aka "Internet Explorer Security Feature Bypass Vulnerability."

The User Mode Code Integrity (UMCI) implementation in Device Guard in Microsoft Internet Explorer 11 allows remote attackers to bypass a code-signing protection mechanism via unspecified vectors, aka "Internet Explorer Security Feature Bypass."

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.

Microsoft Internet Explorer 8, and possibly other versions, detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."

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.

Cross-domain vulnerability in Microsoft Internet Explorer 5.01 SP4, 6, and 7 allows remote attackers to access restricted information from other domains via JavaScript that uses the Object data type for the value of a (1) location or (2) location.href property, related to incorrect determination of the origin of web script, aka "Window Location Property Cross-Domain Vulnerability." NOTE: according to Microsoft, CVE-2008-2948 and CVE-2008-2949 are duplicates of this issue, probably different attack vectors.
