Test ID:1.3.6.1.4.1.25623.1.0.104634
Category:General
Title:OpenBSD OpenSSH 8.9 - 9.2 Unspecified Vulnerability
Summary:OpenBSD OpenSSH is prone to an unspecified vulnerability.
Description:Summary:
OpenBSD OpenSSH is prone to an unspecified vulnerability.

Vulnerability Insight:
ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
per-hop destination constraints (ssh-add -h ...) added in OpenSSH 8.9, a logic error prevented the
constraints from being communicated to the agent. This resulted in the keys being added without
constraints. The common cases of non-smartcard keys and keys without destination constraints are
unaffected. This problem was reported by Luci Stanescu.

Affected Software/OS:
OpenBSD OpenSSH versions starting from 8.9 and prior to 9.3.

Solution:
Update to version 9.3 or later.

CVSS Score:
10.0

CVSS Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C
