How to fix?

Upgrade SLES:15.5 apache-sshd to version 2.19.0-150200.5.16.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream apache-sshd package and not the apache-sshd package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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.
