Summary
Path traversal in the sshd-scp component of Apache MINA SSHD. Apache MINA SSHD is a Java library for client-side and server-side SSH.
The implementation of receiving files or directories via SCP did not validate filenames in SCP "C" or "D" commands. A malicious sender could send filenames containing paths, resulting in files to be written in attacker-controlled places.
The issue affects only * applications that use no longer supported Apache MINA SSHD versions = 2.0.0 to receive files. Applications using Apache MINA SSHD >= 2.0.0 not using sshd-scp are not affected.
Affected applications are advised to upgrade to these versions.
