1) Improper Authorization
EUVDB-ID: #VU82973
Risk: Low
CVSSv3.1: 6.6 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-40660
CWE-ID:
CWE-285 - Improper Authorization
Exploit availability: No
DescriptionThe 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.
MitigationInstall updates from vendor's repository.
