Description

This security bulletin contains information about 1 vulnerability.

1) Improper Authorization (CVE-ID: CVE-2023-40660)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows an attacker to bypass authorization process.

The vulnerability exists due to a logic error in the authorization process. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. An attacker with physical proximity to the system can bypass the OS logon/screen for small permanently connected tokens to computers.

Remediation

Install update from vendor's website.
