CVE-2019-0231: Apache MINA SSLFilter security Issue

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.

Security readout for executives and security teams

Apache MINA had a TLS shutdown handling flaw where a close_notify message did not properly close the connection. Affected servers could keep sockets open, and clients could potentially receive cleartext messages after TLS closure. The public source bundle does not provide a CVSS score or active exploitation evidence. Exposure is most likely in applications or services using Apache MINA SSLFilter, especially network-facing services that terminate TLS through MINA. The bundle does not identify specific downstream products or deployment patterns. Treat as a targeted dependency hygiene issue unless MINA SSLFilter is used on exposed production services. Prioritize confirmation and upgrade for internet-facing systems because the issue involves TLS connection handling and possible cleartext exposure. Mitigation focus: Upgrade MINA 2.0.20 deployments to 2.0.21.; Upgrade MINA 2.1.0 deployments to 2.1.1.; Check Apache MINA release guidance before changing unsupported versions..
