Summary
Apache MINA SSHD information disclosure vulnerability
Details

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.
