CVE-2005-1794

Hi,

I'm concerned that a number of web sites wrongly claim or imply that the vulnerability described in CVE-2005-1794 doesn't apply to xrdp, e.g.,  see

http://people.canonical.com/~ubuntu-security/cve/2005/CVE-2005-1794.html

and

https://security-tracker.debian.org/tracker/CVE-2005-1794

(As a result of this misinformation, we almost dismissed the report from our vulnerability scanner as a false positive.  There are of course many situations in which this vulnerability is not a problem, and in fact we're considering it a low priority, but in some environments this could have been a serious oversight.)

The descriptions of this CVE on sites like Mitre, Secunia, etc., generally make no mention of xrdp either way, but the way the vulnerability is described could easily lead people to assume that it does not apply to xrdp.

I'm intending to discuss this with some of the relevant organizations, with the intent of either adding references to xrdp to the most prominent online sources or perhaps issuing a new CVE; I'm not sure what the precedent is in cases like this.  However, I thought I should discuss it with you first, in case you wanted to coordinate, or be CC'd in, or whatever.

Thoughts?

  Harry.

XRDP 0.9.0 (devel), Debian 7.5 and Rage XL 2D graphics

Hi,

I have XRDP 0.9.0 (devel) built using O-Matic and working on a clean install of Debian 7.5 on several servers with  Rage XL 2D graphics cards and can use xfce with X11rdp  OK.  However, I have failed to get Gnome fallback working with sesman-X11rdp, even after setting my  .xsession to:

gnome-session --session=gnome-fallback


The Debian background is visible for half a second before being replaced by the “Oh No – Something has gone wrong screen”.  There is nothing useful in the xrdp log.


If I connect via sesman-Xvnc then Gnome fallback (MetaCity) works fine – usually after the second (sic) attempt !  However, this doesn’t support copy & paste.


The physical machines start OK with Gnome, which run in fallback mode (MetaCity).


I get the same symptoms when running Debian 7.5 and xrdp 0.9.0 on a virtual machine running on a MacbookPro with 3D graphics enabled.


There is lots on the web saying that Gnome doesn’t work with 2D graphics but that Gnome fallback should.


Question:  Has anyone got Gnome fallback working via X11rdp.  If so how, is this on a 2D graphics machine and what diagnostics do you recommend ?


A bug report that might be relevant:

Clipboard on xrdp 0.6.1

Hello

I was installed Xrdp 0.6.1 on my Ubuntu Server 14.04.1 with KDE GUI and my clipboard doesn't work.
I read yours document about working clipboard:


Should I make additional configuration? 
I use internal RDP service from Windows 7 to connect with Ubuntu Server - work great but I can't copy/paste from Windows-Linux/Linux-Windows folders, files and plain text.

Regards

Spanish keyboard devel brach

Hi,
I'm using devel branch on Debian 7, compiled from "x11rdp-o-matic" script, with Linux/MS/Android/iOS/MacOS clients, and using LXDE and Matchbox environments.
Now, our only issue is configuring Spanish keyboard.
I'm trying with commands like " setxkbmap -layout 'es,es' -model pc105" and "xrdp-genkeymap /etc/xrdp/km-040a.ini", without success.

Recent changes had added the configuration file : /etc/xrdp/xrdp_keyboard.ini
I have added two lines:

[default_rdp_layouts]
...
rdp_layout_es=0x0000040A

[default_layouts_map]
...
rdp_layout_es=es


Now, every client can login with Spanish keyboard.
Is this the correct way?

Thanks for your work.

XRDP v 0.8 and problems with access from Mac OS X 10.9.4 - negotiating credentials fails

I have built a clean build of Debian 7.5 (Wheezy) and installed XRDP 0.8
using x11rdp-o-matic (See URL: 
http://scarygliders.net/x11rdp-o-matic-information/).  This works fine
(including copy & paste) when accessed from both Windows 7.1 using the
Microsoft RDP client and from Windows 8.1.

However when connecting from Apple Mac OS X 10.9.4 using Microsoft Remote
Desktop Version 8.0.8 (Build 25010) I get a black screen showing
"Negotiating Credentials" for about 1 second after which the connection
terminates.

The MRD log is:
[2014-Jul-31 11:09:51] RDP (0): ----- BEGIN ACTIVE CONNECTION -----
[2014-Jul-31 11:09:51] RDP (0): client version: 8.0.25010

ProtocolDisconnected(8)
[2014-Jul-31 11:09:52] RDP (0): ------ END ACTIVE CONNECTION ------

This seems to be a problem affecting a number of people.

Happy to investigate further if anyone can guide me.

Close XRDP if login fails

I've set the "required credential" value in configuration file as true. It
works (when I try to connect with freerdp without specify an user, the
connexion is not created). But when I write a wrong password, it shows the
XRDP login windows. What I need when the user specify a wrong password, is
close connection and don't show the login window. 

Is it possible??
Thanks!!!

XFCE not exiting cleanly

Hi,

we are providing a remote desktop using Xrdp on Debian sid, and the sessions 
runs XFCE.

When logging out in XFCE, the session is not cleanly exited. Processes still 
stick around after logging out, sometimes only one or two, sometimes more, but 
that keeps Xvnc from exiting, slowly eating up the Xrdp session limit.

That does not happen when logging in through lightdm locally.

How do I find out what is wrong when the session isrunning in Xrdp?

I need urgently ur help

Hello,

My Name is Roshaan, im from Germany and studying IT, right now i write a Bachelor thesis about Remote Desktop Protocol.
My professor wants to know:

What structure have the RDP messages?

I have researched everywhere not found, I hope that you can help me further

xrdp configure problem

Hi Guys,

we are using xrdp on other machines, works great. 

I have been trying to build xrdp on a new linux platform running slackware v14. XRDP verion is 0.6.1.

I do not have pam so I ran configure with --enable-nopam. I got an error message - see attached jpegs. The file Xlib.h exists and I can open it. 

For xrdp I have Xvnc 1.3.10 from www.tightvnc.com.

Any ideas please?
