CVE-2026-56452

Estado: AnalizadaAlta (7.5)—

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 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.

Detalles técnicos trazas, registros y código del informe original
  *  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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Path traversal en SCP permite a atacante remoto escribir archivos en ubicaciones controladas (CWE-22). CVSS AV:N/AC:L/PR:N/UI:N indica acceso remoto sin autenticación: T1190. Impacto: manipulación de datos (T1565.001) por sobrescritura de ficheros, lectura de datos (T1005) si se lee contenido.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
