 Vulnerability Advisories

JTEKT TOYOPUC products – CVE-2021-27458

An attacker could prevent Ethernet communication from being established in the affected products by manipulating the link parameter or changing its state.

JTEKT Corporation recommends that users apply the suggested mitigation so an unauthorized user cannot stop the establishment of Ethernet communications between devices.

WAGO 750 Series Denial of Service – CVE-2018-8836

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. This may result in a denial-of-service condition relating to communications with commissioning and service tools.
