CVSS v3.1
Official Description
WRQ Reflection for Secure IT Windows Server 6.0 (formerly known as F-Secure SSH server) processes access and deny lists in a case-sensitive manner, when previous versions were case-insensitive, which might allow remote attackers to bypass intended restrictions and login to accounts that should be denied.
Technical Analysis
CVE-2005-2771 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
