IIS 4.0 and 5.0 allows remote attackers to read documents outside of the web root, and possibly execute arbitrary commands, via malformed URLs that contain UNICODE encoded characters, aka the "Web Server Folder Traversal" vulnerability.Show less

The Cenroll ActiveX control (xenroll.dll) for Terminal Server Editions of Windows NT 4.0 and Windows NT Server 4.0 before SP6 allows remote attackers to cause a denial of service (resource consumption) by creating a large number of arbitrary files on the target machine.Show less

Microsoft Virtual Machine (VM) in Internet Explorer 4.x and 5.x allows an unsigned applet to create and use ActiveX controls, which allows a remote attacker to bypass Internet Explorer's security settings and execute arbitrary commands via a malicious web page or email, aka the "Microsoft VM ActiveX Component" vulnerability.Show less

Buffer overflow in the System Monitor ActiveX control in Windows 2000 allows remote attackers to execute arbitrary commands via a long LogFileName parameter in HTML source code, aka the "ActiveX Parameter Validation" vulnerability.Show less

Microsoft Exchange Server 5.5 does not properly handle a MIME header with a blank charset specified, which allows remote attackers to cause a denial of service via a charset="" command, aka the "Malformed MIME Header" vulnerability.Show less

Microsoft Windows 2000 before Service Pack 2 (SP2), when running in a non-Windows 2000 domain and using NTLM authentication, and when credentials of an account are locally cached, allows local users to bypass account lockout policies and make an unlimited number of login attempts, aka the "Domain Account Lockout" vulnerability.Show less

When a Microsoft Office 2000 document is launched, the directory of that document is first used to locate DLL's such as riched20.dll and msi.dll, which could allow an attacker to execute arbitrary commands by inserting a Trojan Horse DLL into the same directory as the document.Show less

The Windows 2000 telnet client attempts to perform NTLM authentication by default, which allows remote attackers to capture and replay the NTLM challenge/response via a telnet:// URL that points to the malicious server, aka the "Windows 2000 Telnet Client NTLM Authentication" vulnerability.Show less

The web-based folder display capability in Microsoft Internet Explorer 5.5 on Windows 98 allows local users to insert Trojan horse programs by modifying the Folder.htt file and using the InvokeVerb method in the ShellDefView ActiveX control to specify a default execute option for the first file that is listed in the folder.Show less

IIS 4.0 and 5.0 does not properly restrict access to certain types of files when their parent folders have less restrictive permissions, which could allow remote attackers to bypass access restrictions to some files, aka the "File Permission Canonicalization" vulnerability.Show less
