Description
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 and use the SCP functions to receive files,
* or applications using sshd-scp in Apache MINA SSHD >= 2.0.0 to receive files.
Applications using Apache MINA SSHD >= 2.0.0 not using sshd-scp are not affected.
The issue is fixed in Apache MINA 2.19.0 and 3.0.0-M5. Affected applications are advised to upgrade to these versions.
