medium Nessus Network Monitor Plugin ID 3331

Synopsis

The remote host is vulnerable to a buffer overflow.

Description

The remote host is running a version of the Dropbear SSH server prior to 0.47.0 that is vulnerable to a remote buffer overflow. An attacker exploiting this flaw would need to be able to log into a valid account. After logging in, the user would send a malformed request to the SSH server which would result in a buffer overflow and execution of arbitrary code.

Solution

Upgrade to version 0.47.0 or higher.
