An attacker that opened a named pipe with the same name can use it to gain the token of another user by listening for connections and abusing ImpersonateNamedPipeClient(). The iTopVPNmini.exe component of iTop VPN 3.2 will try to connect to datastate_iTopVPN_Pipe_Server on a loop. When the path of the program to be executed is sent, there is a local privilege escalation in which the service program executes the path with system privileges. A thread may exist with a specific command. In addition, the service program does not verify the user when communicating. In this case, the Named Pipe is also given Read and Write rights to the general user. The user process communicates with a service of system authority called ACCsvc through a named pipe. When the path of the program to be executed is sent, there is a local privilege escalation in which the service program executes the path with system privileges.Īcer Care Center 4.00.30xx before contains a local privilege escalation vulnerability.

Jenkins WMI Windows Agents Plugin 1.8 and earlier includes the Windows Remote Command library which has a buffer overflow vulnerability that may allow users able to connect to a named pipe to execute commands on the Windows agent machine.Īcer QuickAccess 2.01.300x before and 3.00.30xx before contains a local privilege escalation vulnerability. Typically, after the BSOD, the victim SMBv3 server will reboot. For most systems, this attack requires authentication, except in the special case of Windows Domain Controllers, where unauthenticated users can always open named pipes as long as they can establish an SMB session. By sending a malformed FileNormalizedNameInformation SMBv3 request over a named pipe, an attacker can cause a Blue Screen of Death (BSOD) crash of the Windows kernel.

Microsoft Windows SMBv3 suffers from a null pointer dereference in versions of Windows prior to the April, 2022 patch set. Nokia Fastmile 3tg00118abad52 is affected by an authenticated path traversal vulnerability which allows attackers to read any named pipe file on the system. As a workaround, ensure that `pipe_mode` is set first after initializing a `ServerOptions`. Named pipes were introduced to Tokio in version 1.7.0, so releases older than 1.7.0 are not affected. The fix will also be present in all releases starting from version 1.24.0. Remote clients may only access the named pipe if the named pipe's associated path is accessible via a publicly shared folder (SMB). If the application has previously configured `reject_remote_clients` to `true`, this effectively undoes the configuration. Starting with version 1.7.0 and prior to versions 1.18.4, 1.20.3, and 1.23.1, when configuring a Windows named pipe server, setting `pipe_mode` will reset `reject_remote_clients` to `false`.

Tokio is a runtime for writing applications with Rust. A local authenticated malicious user could potentially send malicious input to a named pipe in order to elevate privileges on the system. Dell Alienware Command Center versions 5.5.37.0 and prior contain an Improper Input validation vulnerability.
