6.1
CVSS v3.1
Official Description
Open redirect vulnerability in Cybozu Garoon 4.2.4 to 4.10.1 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via the Login Screen.
Technical Analysis
CVE-2019-5946 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
