CVE-2019-0231: Apache Mina

High severity, CVSS 7.5. EPSS: 2.1% chance of exploitation in the next 30 days.

Handling of the close_notify SSL/TLS message does not lead to a connection closure, leading the server to retain the socket opened and to have the client potentially receive clear text messages afterward. Mitigation: 2.0.20 users should migrate to 2.0.21, 2.1.0 users should migrate to 2.1.1. This issue affects: Apache MINA.

Affected products

• Apache Mina: version 2.0.20 only; version 2.1.1 only
