VAR-201610-0668
Vulnerability from variot - Updated: 2025-11-18 15:29Beckhoff 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 is an industrial control system that is installed in the control cabinet and can be functionally configured. Automation Device Specification (ADS) TwinCAT Components is a PC real-time controller software product. Beckhoff Embedded PC images have a security vulnerability in versions prior to 2014-10-22 and in the Automation Device Specificatios TwinCAT component. Multiple Beckhoff Products are prone to multiple security-bypass vulnerabilities. Successfully exploiting these issues may allow attackers to perform unauthorized actions. This may lead to other attacks

VAR-201610-0667
Vulnerability from variot - Updated: 2025-11-18 15:29Beckhoff 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. Supplementary information : CWE Vulnerability type by CWE-254: Security Features ( Security function ) Has been identified. http://cwe.mitre.org/data/definitions/254.htmlRound robin by a third party (brute-force) Access may be gained through an attack. Beckhoff Embedded PC Images is an industrial control system that is installed in the control cabinet and can be functionally configured. A remote attacker can exploit the vulnerability to gain access by implementing a brute force attack. Multiple Beckhoff Products are prone to multiple security-bypass vulnerabilities. Successfully exploiting these issues may allow attackers to perform unauthorized actions. This may lead to other attacks

"data": "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. Supplementary information : CWE Vulnerability type by CWE-254: Security Features ( Security function ) Has been identified. http://cwe.mitre.org/data/definitions/254.htmlRound robin by a third party (brute-force) Access may be gained through an attack. Beckhoff Embedded PC Images is an industrial control system that is installed in the control cabinet and can be functionally configured. A remote attacker can exploit the vulnerability to gain access by implementing a brute force attack. Multiple Beckhoff Products are prone to multiple security-bypass vulnerabilities. \nSuccessfully exploiting these issues may allow attackers to perform unauthorized actions. This may lead to other attacks",

VAR-201506-0271
Vulnerability from variot - Updated: 2025-04-13 23:34Beckhoff 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. Supplementary information : CWE Vulnerability type by CWE-284: Improper Access Control ( Inappropriate access control ) Has been identified. http://cwe.mitre.org/data/definitions/284.htmlService disruption through a crafted request by a third party ( Reboot or shutdown ) It can be unspecified, such as being in a state or creating an arbitrary user. Beckhoff IPC Diagnostics is a set of support software pre-installed in all Beckhoff IPC/PLC (Programmable Logic Controllers) running on the Microsoft Windows operating system. Beckhoff IPC diagnostics is prone to multiple authentication-bypass vulnerabilities. An attacker can exploit these issues to bypass the authentication mechanism and perform unauthorized actions. This may aid in further attacks

VAR-201109-0179
Vulnerability from variot - Updated: 2025-04-11 23:05Beckhoff 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 TwinCAT is a PC-based software solution that provides complete CNC functionality. TwinCAT is prone to a denial-of-service vulnerability. Attackers can exploit this issue to crash the application, denying service to legitimate users. TwinCAT 2.11 R2 Build 2032 is vulnerable. Other versions may also be affected

VAR-201911-0393
Vulnerability from variot - Updated: 2024-11-23 23:11When Beckhoff TwinCAT is configured to use the Profinet driver, a denial of service of the controller could be reached by sending a malformed UDP packet to the device. This issue affects TwinCAT 2 version 2304 (and prior) and TwinCAT 3.1 version 4204.0 (and prior). Beckhoff TwinCAT Contains a vulnerability related to division by zero.Service operation interruption (DoS) There is a possibility of being put into a state. Beckhoff TwinCAT is a software system consisting of a real-time environment and a real-time system that executes control programs in the development environment of the German Beckhoff company. This system is mainly used for PLC (Programmable Logic Controller) programming, diagnostics, and system configuration.
There are security vulnerabilities in Beckhoff TwinCAT 2 Build 2304 and earlier and 3.1 Build 4024.0 and earlier

VAR-201803-2203
Vulnerability from variot - Updated: 2024-11-23 22:52Kernel drivers in Beckhoff TwinCAT 3.1 Build 4022.4, TwinCAT 2.11 R3 2259, and TwinCAT 3.1 lack proper validation of user-supplied pointer values. An attacker who is able to execute code on the target may be able to exploit this vulnerability to obtain SYSTEM privileges. Beckhoff TwinCAT Contains an input validation vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The Beckhoff TwinCAT system software \"remodels\" any compatible PC into a real-time controller with a multi-PLC system, NC axis control system, programming environment and operator station, replacing traditional PLC and NC/CNC controllers and operating equipment. There is an untrusted pointer reference vulnerability in TwinCAT. Beckhoff TwinCAT is prone to multiple local privilege-escalation vulnerabilities. Beckhoff TwinCAT 2 and 3.1 are vulnerable

VAR-201912-1212
Vulnerability from variot - Updated: 2024-11-23 22:51Beckhoff Embedded Windows PLCs through 3.1.4024.0, and Beckhoff Twincat on Windows Engineering stations, allow an attacker to achieve Remote Code Execution (as SYSTEM) via the Beckhoff ADS protocol. Beckhoff Embedded Windows PLCs and Beckhoff Twincat Contains an input validation vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. Beckhoff TwinCAT is a set of programming software for programmable logic controllers (PLCs) from the German company Beckhoff.
There are security holes in Beckhoff TwinCAT 2/3. An attacker could use the Beckhoff ADS protocol to exploit this vulnerability to execute code with SYSTEM permissions
