Yubico YubiKey 5 Series devices with firmware before 5.7.0 and YubiHSM 2 devices with firmware before 2.4.0 allow an ECDSA secret-key extraction attack (that requires physical access and expensive equipment) in which an electromagnetic side channel is present because of a non-constant-time modular inversion for the Extended Euclidean Algorithm, aka the EUCLEAK issue. Other uses of an Infineon cryptographic library may also be affected.

- BehobenFirmware <4.52 installed on CODESYS Key series 3codesys_psirt
Update the CODESYS Key firmware to version 4.52. Updating the firmware also protects the future usage of additional CODESYS Key features by the CODESYS software and general usage by other software. The update can be installed, for example, via the CodeMeter Control Center.
- BehobenFirmware 4.5.2phoenix_contact_psirt
Phoenix Contact strongly recommends upgrading affected ESL STICK USB A s to firmware version 4.5.2 which fixes this vulnerability.

Phoenix Contact strongly recommends upgrading affected ESL STICK USB A s to firmware version 4.5.2 which fixes this vulnerability.
https://www.wibu.com/support/faq/codemeter-hardware-general.html#faq-29694 - MitigationFirmware <4.52 installed on CODESYS Key series 3codesys_psirt
Regardless of the vulnerability described here, CODESYS GmbH recommends that physical access to the CODESYS Key should only be granted to authorized persons. Especially in the case of productive control systems, removal of the CODESYS Key can affect the controlled machine or process. This generally recommended restriction of access also reduces the attack surface for this vulnerability, as its exploitation requires physical access.
