Paramiko en versiones 2.4.1, 2.3.2, 2.2.3, 2.1.5, 2.0.8, 1.18.5 y 1.17.6 contiene una vulnerabilidad de control de acceso incorrecto en el servidor SSH que puede resultar en la ejecución remota de código. Este ataque parece ser explotable mediante conectividad de red.
The python-paramiko package provides a Python module that implements the SSH2 protocol for encrypted and authenticated connections to remote machines. Unlike SSL, the SSH2 protocol does not require hierarchical certificates signed by a powerful central authority. The protocol also includes the ability to open arbitrary channels to remote services across an encrypted tunnel. Issues addressed include a bypass vulnerability.
