CVE-2009-1477
CWE-310Published: May 27, 2009· Updated: Jun 16, 2026

CVSS v3.1
Official Description
The https web interfaces on the ATEN KH1516i IP KVM switch with firmware 1.0.063, the KN9116 IP KVM switch with firmware 1.1.104, and the PN9108 power-control unit have a hardcoded SSL private key, which makes it easier for remote attackers to decrypt https sessions by extracting this key from their own switch and then sniffing network traffic to a switch owned by a different customer.
Technical Analysis
CVE-2009-1477 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.
