The default configuration of Microsoft Windows uses the Web Proxy Autodiscovery Protocol (WPAD) without static WPAD entries, which might allow remote attackers to intercept web traffic by registering a proxy server using WINS or DNS, then responding to WPAD requests, as demonstrated using Internet Explorer. NOTE: it could be argued that if an attacker already has control over WINS/DNS, then web traffic could already be intercepted by modifying WINS or DNS records, so this would not cross privilege boundaries and would not be a vulnerability. It has also been reported that DHCP is an alternate attack vector.

Microsoft Data Access Component Internet Publishing Provider 8.103.2519.0 and earlier allows remote attackers to bypass Security Zone restrictions via WebDAV requests.

Information disclosure vulnerability in Microsoft Windows 2000 telnet service allows remote attackers to determine the existence of user accounts such as Guest, or log in to the server without specifying the domain name, via a malformed userid.

The HTML Help facility in Microsoft Windows 98, 98 Second Edition, Millennium Edition, NT 4.0, NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP uses the Local Computer Security Zone when opening .chm files from the Temporary Internet Files folder, which allows remote attackers to execute arbitrary code via HTML mail that references or inserts a malicious .chm file containing shortcuts that can be executed, aka "Code Execution via Compiled HTML Help File."

Integer overflow in the CryptoAPI component in Microsoft Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 allows man-in-the-middle attackers to spoof arbitrary SSL servers and other entities via an X.509 certificate that has a malformed ASN.1 Object Identifier (OID) and was issued by a legitimate Certification Authority, aka "Integer Overflow in X.509 Object Identifiers Vulnerability."

Buffer overflows in Microsoft Network Monitor (Netmon) allow remote attackers to execute arbitrary commands via a long Browser Name in a CIFS Browse Frame, a long SNMP community name, or a long username or filename in an SMB session, aka the "Netmon Protocol Parsing" vulnerability. NOTE: It is highly likely that this candidate will be split into multiple candidates.

Microsoft Windows XP and Windows 2000, when configured to send administrative alerts and the "Do not overwrite events (clear log manually)" option is set, does not notify the administrator when the log reaches its maximum size, which allows local users and remote attackers to avoid detection.

The Windows Media Player control in Microsoft Windows 2000 allows remote attackers to execute arbitrary script in the local computer zone via an ASX filename that contains javascript, which is executed in the local context in a preview panel.

DHCP clients with ICMP Router Discovery Protocol (IRDP) enabled allow remote attackers to modify their default routes.

The registry in Windows NT can be accessed remotely by users who are not administrators.

Buffer overflow in the Microsoft Message Queue Manager (MSQM) allows remote attackers to cause a denial of service (RPC service crash) via a queue registration request.

By default, DNS servers on Windows NT 4.0 and Windows 2000 Server cache glue records received from non-delegated name servers, which allows remote attackers to poison the DNS cache via spoofed DNS responses.

Ezboo webstats, possibly 3.0.3, allows remote attackers to bypass authentication and gain access via a direct request to (1) update.php and (2) config.php.

Buffer overflow in the ShellExecute API function of SHELL32.DLL in Windows 2000 before SP4 may allow attackers to cause a denial of service or execute arbitrary code via a long third argument.

A NETBIOS/SMB share password is the default, null, or missing.

The cryptographic challenge of SMB authentication in Windows 95 and Windows 98 can be reused, allowing an attacker to replay the response and impersonate a user.

Terminal Services Manager MMC in Windows 2000 and XP trusts the Client Address (IP address) that is provided by the client instead of obtaining it from the packet headers, which allows clients to spoof their public IP address, e.g. through a Network Address Translation (NAT).

NETBIOS share information may be published through SNMP registry keys in NT.

Macintosh clients, when using NT file system volumes on Windows 2000 SP1, create subdirectories and automatically modify the inherited NTFS permissions, which may cause the directories to have less restrictive permissions than intended.

Microsoft Windows 2000 before Update Rollup 1 for SP4 does not record the IP address of a Windows Terminal Services client in a security log event if the client connects successfully, which could make it easier for attackers to escape detection.

The SECEDIT command on Microsoft Windows 2000 before Update Rollup 1 for SP4, when using a security template to set Access Control Lists (ACLs) on folders, does not apply ACLs on folders that are listed after a long folder entry, which could result in less secure permissions than specified by the template.

Unspecified vulnerability in the Servlet Engine/Web Container in IBM WebSphere Application Server (WAS) before 6.1.0.7 has unknown impact and attack vectors.

Buffer overflow in a function in User32.dll on Windows NT through Server 2003 allows local users to execute arbitrary code via long (1) LB_DIR messages to ListBox or (2) CB_DIR messages to ComboBox controls in a privileged application.

The NtSetLdtEntries function in the programming interface for the Local Descriptor Table (LDT) in Windows NT 4.0 and Windows 2000 allows local attackers to gain access to kernel memory and execute arbitrary code via an expand-down data segment descriptor descriptor that points to protected memory.

The Utility Manager in Microsoft Windows 2000 executes winhlp32.exe with system privileges, which allows local users to execute arbitrary code via a "Shatter" style attack using a Windows message that accesses the context sensitive help button in the GUI, as demonstrated using the File Open dialog in the Help window, a different vulnerability than CVE-2004-0213.

The component for the Virtual DOS Machine (VDM) subsystem in Windows NT 4.0 and Windows 2000 does not properly validate system structures, which allows local users to access protected kernel memory and execute arbitrary code.

A Windows NT domain user or administrator account has a default, null, blank, or missing password.

Windows NT RSHSVC program allows remote users to execute arbitrary commands.

Unspecified vulnerability in the kernel in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, through Vista SP1, and Server 2008 allows local users to execute arbitrary code via unknown vectors related to improper input validation. NOTE: it was later reported that one affected function is NtUserFnOUTSTRING in win32k.sys.

The Graphics Rendering Engine in Microsoft Windows 2000 through 2000 SP4 and Windows XP through SP2 maps GDI Kernel structures on a global shared memory section that is mapped with read-only permissions, but can be remapped by other processes as read-write, which allows local users to cause a denial of service (memory corruption and crash) and gain privileges by modifying the kernel structures.

Microsoft Windows does not properly enforce the Autorun and NoDriveTypeAutoRun registry values, which allows physically proximate attackers to execute arbitrary code by (1) inserting CD-ROM media, (2) inserting DVD media, (3) connecting a USB device, and (4) connecting a Firewire device; (5) allows user-assisted remote attackers to execute arbitrary code by mapping a network drive; and allows user-assisted attackers to execute arbitrary code by clicking on (6) an icon under My Computer\Devices with Removable Storage and (7) an option in an AutoPlay dialog, related to the Autorun.inf file. NOTE: vectors 1 and 3 on Vista are already covered by CVE-2008-0951.

Microsoft SQL Server before Windows 2000 SP4 allows local users to gain privileges as the SQL Server user by calling the xp_fileexist extended stored procedure with a named pipe as an argument instead of a normal file.
