GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

VAR-201804-1569

Vulnerability from variot - Updated: 2023-12-18 13:33

Wago 750 Series PLCs with firmware version 10 and prior include a remote attack may take advantage of an improper implementation of the 3 way handshake during a TCP connection affecting the communications with commission and service tools. Specially crafted packets may also be sent to Port 2455/TCP/IP, used in Codesys management software, which may result in a denial-of-service condition of communications with commissioning and service tools. Wago 750 series PLC Vulnerabilities exist in the firmware of improper shutdown and release of resources.Service operation interruption (DoS) There is a possibility of being put into a state. 750-880, 750-881, 750-852, etc. are all WAGO750 series Ethernet switches. The WAGO750 series has a denial of service vulnerability that can be exploited to cause a denial of service state to communicate with debug and service tools. Multiple WAGO Products are prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause denial-of-service condition. WAGO 750 Series PLCs, etc. are editable logic controller products of Germany WAGO Company. There is a security vulnerability in WAGO 750 Series PLCs using firmware version 10 and earlier. The vulnerability is caused by the program not implementing the three-way handshake correctly

    "data": "Wago 750 Series PLCs with firmware version 10 and prior include a remote attack may take advantage of an improper implementation of the 3 way handshake during a TCP connection affecting the communications with commission and service tools. Specially crafted packets may also be sent to Port 2455/TCP/IP, used in Codesys management software, which may result in a denial-of-service condition of communications with commissioning and service tools. Wago 750 series PLC Vulnerabilities exist in the firmware of improper shutdown and release of resources.Service operation interruption (DoS) There is a possibility of being put into a state. 750-880, 750-881, 750-852, etc. are all WAGO750 series Ethernet switches. The WAGO750 series has a denial of service vulnerability that can be exploited to cause a denial of service state to communicate with debug and service tools. Multiple WAGO Products are prone to a denial-of-service vulnerability. \nAn attacker can exploit this issue to cause denial-of-service condition. WAGO 750 Series PLCs, etc. are editable logic controller products of Germany WAGO Company. There is a security vulnerability in WAGO 750 Series PLCs using firmware version 10 and earlier. The vulnerability is caused by the program not implementing the three-way handshake correctly",
