- Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Software Foundation Apache MINA. In SFTP servers implemented using Apache MINA SSHD that use a RootedFileSystem, logged users may be able to discover "exists/does not exist" information about items outside the rooted tree via paths including parent navigation ("..") beyond the root, or involving symlinks. This issue affects Apache MINA: from 1.0 before 2.9.3 Users are recommended to upgrade to 2.9.3 Until version 2.1.0, some of the code affected by this vulnerability appeared in org.apache.sshd:sshd-core. Version 2.1.0 contains a commit where the code was moved to the package org.apache.sshd:sshd-common, which did not exist until version 2.1.0.
Recommended action: Upgrade to 2.9.3 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
