What is CVE-2019-3463?

The vulnerability in rssh arises from insufficient sanitization of arguments within the tool. As a result, attackers may bypass the intended restrictions of rssh, which is designed to limit user operations strictly to rsync. This oversight leads to the potential execution of arbitrary shell commands, posing a significant security risk for systems relying on this restricted shell functionality.

Affected Version(s)

rssh All versions before 2.3.4-5+deb9u2 and 2.3.4-10
