Internet Explorer

Microsoft Internet Explorer 5.01, 5.5 and 6.0 does not properly check the Cascading Style Sheet input parameter for Modal dialogs, which allows remote attackers to read files on the local system via a web page containing script that creates a dialog and then accesses the target files, aka "Modal Dialog script execution."Show less

Microsoft Internet Explorer 5.01, 5.5 and 6.0 does not properly check parameters that are passed during third party rendering, which could allow remote attackers to execute arbitrary web script, aka the "Third Party Plugin Rendering" vulnerability, a different vulnerability than CVE-2003-0233.Show less

Buffer overflow in URLMON.DLL in Microsoft Internet Explorer 5.01, 5.5 and 6.0 allows remote attackers to execute arbitrary code via an HTTP response containing long values in (1) Content-type and (2) Content-encoding fields.Show less

The showHelp() function in Microsoft Internet Explorer 5.01, 5.5, and 6.0 supports certain types of pluggable protocols that allow remote attackers to bypass the cross-domain security model and execute arbitrary code, aka "Improper Cross Domain Security Validation with ShowHelp functionality."Show less

Microsoft Internet Explorer 5.5 and 6.0 allows remote attackers to bypass the cross-domain security model to run malicious script or arbitrary programs via dialog boxes, aka "Improper Cross Domain Security Validation with dialog box."Show less

Microsoft Internet Explorer 6.0 and possibly others allows remote attackers to upload arbitrary file contents when users press a key corresponding to the JavaScript (1) event.ctrlKey or (2) event.shiftKey onkeydown event contained in a webpage. NOTE: it was reported that the vendor has disputed the severity of this issue.Show less

Internet Explorer 6.0 does not warn users when an expired certificate authority (CA) certificate is submitted to the user and a newer CA certificate is in the user's local repository, which could allow remote attackers to decrypt web sessions via a man-in-the-middle (MITM) attack.Show less

Cross-site scripting (XSS) vulnerability in ftp.htt in Internet Explorer 5.5 and 6.0, when running on Windows 2000 with "Enable folder view for FTP sites" and "Enable Web content in folders" selected, allows remote attackers to inject arbitrary web script or HTML via the hostname portion of an FTP URL.Show less

Internet Explorer 5.0, 5.0.1 and 5.5 with JavaScript execution enabled allows remote attackers to determine the existence of arbitrary files via a script tag with a src parameter that references a non-JavaScript file, then using the onError event handler to monitor the results.Show less

Microsoft Internet Explorer 5.0.1 through 6.0 on Windows 2000 or Windows XP allows remote attackers to cause a denial of service (crash) via an OBJECT tag that contains a crafted CLASSID (CLSID) value of "CLSID:00022613-0000-0000-C000-000000000046".Show less

Microsoft Internet Explorer 6.0, when handling an expired CA-CERT in a webserver's certificate chain during a SSL/TLS handshake, does not prompt the user before searching for and finding a newer certificate, which may allow attackers to perform a man-in-the-middle attack. NOTE: it is not clear whether this poses a vulnerability.Show less

Microsoft Internet Explorer 5.0 through 6.0 allows remote attackers to cause a denial of service (crash) via an object of type "text/html" with the DATA field that identifies the HTML document that contains the object, which may cause infinite recursion.Show less

The browser history feature in Microsoft Internet Explorer 5.5 through 6.0 allows remote attackers to execute arbitrary script as other users and steal authentication information via cookies by injecting JavaScript into the URL, which is executed when the user hits the Back button.Show less

Internet Explorer 5.5 and 6.0 allows remote attackers to bypass the cross-domain security model and access information on the local system or in other domains, and possibly execute code, via cached methods and objects, aka "Cross Domain Verification via Cached Methods."Show less
