CRITICAL9.8EPSS 0.15%Undertow client not checking server identity presented by server certificate in https connections
Published: 2/23/2023Modified: 4/28/2026
Description
The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.
Affected packages (2)
- Debian/undertowfrom 0, < 2.3.8-2
- Maven/io.undertow:undertow-core>= 2.3.0, < 2.3.5.Final
