FKIE_CVE-2026-56452

Vulnerability from fkie_nvd - Published: 2026-07-20 21:16 - Updated: 2026-07-27 13:49
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
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 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.
