Advantech WebAccess is prone to a buffer overflow vulnerability on the RPC interface that could permit the execution of arbitrary remote code. A remote attacker can exploit this vulnerability to execute arbitrary code and completely compromise the computer.

The specific flaw exists within bwnodeip.exe, which is accessed through the 70022 IOCTL in the webvrpcs process. The process does not properly validate the length of user-supplied data prior to copying it to a fixed-length buffer.

The specific flaw exists within bwnodeip.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The process does not properly validate the length of user-supplied data prior to copying it to a fixed-length buffer.

This vulnerability allows local attackers to escalate privileges on vulnerable installations of VirIT eXplorer Anti-Virus. An attacker must first obtain the ability to execute non-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of crafted IOCTL by the VIAGLT64.SYS kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in an arbitrary write condition. An attacker can leverage this vulnerability to execute arbitrary code under the context of kernel. This module will elevate the privileges of the current agent instead of installing a new one.

The user can write 0 where he wants. This can be used to write SecurityDescriptor and write system processes.

An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory.

An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory.

An elevation of privilege vulnerability exists when Windows improperly handles calls to Advanced Local Procedure Call (ALPC).An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Local DCOM DCE/RPC connections can be reflected back to a listening TCP socket allowing access to an NTLM authentication challenge for LocalSystem user which can be replayed to the local DCOM activation service. An attacker who successfully exploited this vulnerability could bypass security and gain elevated privileges on a targeted system. In order to successfully exploit this vulnerability, the source agent must be running in the context of a Windows service application, as the module require special permissions to create a new agent with elevated privileges.

This module exploits a vulnerability in snapd which incorrectly validates and parses the remote socket address when performing access controls on its UNIX socket. A local attacker could use this to access privileged socket APIs and obtain administrator privileges.
