Name of the Vulnerable Software and Affected Versions Apache MINA SSHD versions prior to 2.0.0 Apache MINA SSHD versions 2.0.0 through 2.18.f

Description A path traversal issue exists in the sshd-scp component of Apache MINA SSHD, a Java library for client-side and server-side SSH. The implementation for receiving files or directories via SCP fails to validate filenames in SCP "C" or "D" commands. This allows a malicious sender to provide filenames containing paths, enabling files to be written in locations controlled by the attacker.

Recommendations Upgrade to version 2.19.0. Upgrade to version 3.0.0-M5.
