Insufficient IOCTL access control allows local relocation of arbitrary physical memory

A local low privileged attacker can move arbitrary physical memory content via TcRouter.sys because of exposed IOCTL function calls resulting in a full compromise of the affected devices.

Insufficient IOCTL access control allows local access to arbitrary physical memory

A local low privileged attacker can access arbitrary physical memory or define its mapping via TcRouter.sys because of exposed IOCTL function calls resulting in a full compromise of the affected devices.

Insufficient IOCTL access control allows local access to I/O ports

A local low privileged attacker or process can access I/O ports via TcRouter.sys because of exposed IOCTL function calls resulting in a full compromise of the affected devices.

Beckhoff: Deserialization of untrusted data by TwinCAT 3 Engineering

An unauthenticated attacker can trick a local user into executing arbitrary commands by opening a deliberately manipulated project file with an affected engineering tool. These arbitrary commands are executed in the user context.

Beckhoff: Performing privileged operations and gaining administrator access

A local low privileged attacker can bypass the authentication of the Device Manager user interface, allowing them to perform privileged operations and gain administrator access.

Beckhoff: Arbitrary code execution within privileged processes

A low privileged remote attacker can execute arbitrary code by sending specially crafted calls to the web service of the Device Manager or locally via an API and can cause integer overflows which then may lead to arbitrary code execution within privileged processes.

Beckhoff: Local command injection via TwinCAT Package Manager

A local user with administrative access rights can enter specialy crafted values for settings at the user interface (UI) of the TwinCAT Package Manager which then causes arbitrary OS commands to be executed.

Beckhoff: XSS Vulnerability in TwinCAT 3 HMI Server

An high privileged remote attacker can inject arbitrary content into the custom CSS field on the affected devices due to improper neutralization of input during web page generation ('Cross-site Scripting').

Beckhoff: Information leak via Beckhoff Device Manager

A low privileged remote attacker may be able to disclose confidential information from the memory of a privileged process by sending specially crafted calls to the Device Manager web service that cause an out-of-bounds read operation under certain circumstances due to ASLR and thereby potentially copy confidential information into a response.

Beckhoff Embedded PC Images and TwinCAT Components Exposed Dangerous Method or Function

Beckhoff Embedded PC images before 2014-10-22 and Automation Device Specification (ADS) TwinCAT components might allow remote attackers to obtain access via the (1) Windows CE Remote Configuration Tool, (2) CE Remote Display service, or (3) TELNET service.

Beckhoff Embedded PC Images and TwinCAT Components Improper Restriction of Excessive Authentication Attempts

Beckhoff Embedded PC images before 2014-10-22 and Automation Device Specification (ADS) TwinCAT components do not restrict the number of authentication attempts, which makes it easier for remote attackers to obtain access via a brute-force attack.

Beckhoff IPC Diagnostics before 1.8 does not properly restrict access to functions in /config, which allows remote attackers to cause a denial of service (reboot or shutdown), create arbitrary users, or possibly have unspecified other impact via a crafted request, as demonstrated by a beckhoff.com:service:cxconfig:1#Write SOAP action to /upnpisapi.

Beckhoff TwinCAT 2.11.0.2004 and earlier allows remote attackers to cause a denial of service via a crafted request to UDP port 48899, which triggers an out-of-bounds read.

Beckhoff: Improper input neutralization vulnerability in the IPC-Diagnostics package in TwinCAT/BSD

The IPC-Diagnostics package in TwinCAT/BSD is susceptible to improper input neutralization by a low-privileged local attacker.

Beckhoff: Open redirect in TwinCAT/BSD package authelia-bhf

The package authelia-bhf included in Beckhoffs TwinCAT/BSD is prone to an open redirect that allows a remote unprivileged attacker to redirect a user to another site. This may have limited impact to integrity and does solely affect anthelia-bhf the Beckhoff fork of authelia.

Beckhoff: Relative path traversal vulnerability through TwinCAT OPC UA Server

TwinCAT OPC UA Server in TF6100 and TS6100 in product versions before 4.3.48.0 or with TcOpcUaServer versions below 3.2.0.194 are prone to a relative path traversal that allow administrators to create or delete any files on the system.

A Denial-of-Service vulnerability exists in BECKHOFF Ethernet TCP/IP Bus Coupler BK9000. After an attack has occurred, the device's functionality can be restored by rebooting.

Incorrect Access Control in Beckhoff Automation GmbH & Co. KG CX9020 with firmware version CX9020_CB3011_WEC7_HPS_v602_TC31_B4016.6 allows remote attackers to bypass authentication via the "CE Remote Display Tool" as it does not close the incoming connection on the Windows CE side if the credentials are incorrect.

BECKHOFF: DoS-Vulnerability for TwinCAT OPC UA Server and IPC Diagnostics UA Server

TwinCAT OPC UA Server in versions up to 2.3.0.12 and IPC Diagnostics UA Server in versions up to 3.1.0.1 from Beckhoff Automation GmbH & Co. KG are vulnerable to denial of service attacks. The attacker needs to send several specifically crafted requests to the running OPC UA server. After some of these requests the OPC UA server is no longer responsive to any client. This is without effect to the real-time functionality of IPCs.

Beckhoff: Privilege Escalation through TwinCat System

The default installation path of the TwinCAT XAR 3.1 software in all versions is underneath C:\TwinCAT. If the directory does not exist it and further subdirectories are created with permissions which allow every local user to modify the content. The default installation registers TcSysUI.exe for automatic execution upon log in of a user. If a less privileged user has a local account he or she can replace TcSysUI.exe. It will be executed automatically by another user during login. This is also true for users with administrative access. Consequently, a less privileged user can trick a higher privileged user into executing code he or she modified this way. By default Beckhoff’s IPCs are shipped with TwinCAT software installed this way and with just a single local user configured. Thus the vulnerability exists if further less privileged users have been added.
