Juniper Networks has acknowledged an older vulnerability in OpenSSH for Netscreen-IDP, which potentially can be exploited by malicious people to overwrite arbitrary files on a vulnerable device.

The problem is that the scp utility doesn't perform proper input validation on file names when transferring them. This can be exploited to overwrite an arbitrary file with the privileges of the user via a directory traversal attack.

Successful exploitation requires that a user connects to a malicious SSH server and transfers a file using the scp utility.

The vulnerability affects version 3.0r2 and prior.

Solution
Updated OpenSSH packages are available via the Juniper Networks CSC Web Portal.
