CERT Advisory CA-99-11 Four Vulnerabilities in the Common Desktop Environment

   Original release date: September 13, 1999
   Last revised: October 04, 1999 Updated vendor information for Sun
     Microsystems, Inc.
   Source: CERT/CC

   A complete revision history is at the end of this file.
   
Systems Affected

   *  Systems running the Common Desktop Environment (CDE)

I. Description
   Multiple vulnerabilities have been identified in some distributions of the
   Common Desktop Environment (CDE). These vulnerabilities are different from
   those discussed in CA-98.02. We recommend that you install appropriate 
   vendor patches as soon as possible (see Section III below). Until you can 
   do so, we encourage you to disable or uninstall vulnerable copies of the 
   CDE package. Note that disabling these programs will severely affect the 
   utility of the CDE environment. 

   At this time, the CERT/CC has not received any reports of these 
   vulnerabilities being exploited by intruders. 
Vulnerability #1: ToolTalk ttsession uses weak RPC authentication mechanism 
   The ToolTalk messaging server ttsession allows independent applications to 
   communicate without having direct knowledge of each other. Applications can  
   communicate through an associated ttsession which delivers messages via RPC 
   calls between interested agents. 

   On many systems, ttsession uses AUTH_UNIX authentication (a client-based 
   security option) by default. When messages are received, ttsession uses 
   certain environment variables supplied by the client to determine how the 
   message is handled. Because of this, the ttsession process can be 
   manipulated to execute unauthorized arbitrary programs with the privileges 
   of the running ttsession. 
Vulnerability #2: CDE dtspcd relies on file-system based authentication
   The network daemon dtspcd (a CDE desktop subprocess control program) 
   accepts CDE requests from clients to execute commands and launch   
   applications remotely. 

   When a client makes a request, the dtspcd daemon asks the client to create 
   a file that has a predictable name so that the daemon can authenticate the 
   request. If a local user can manipulate the files used for authentication, 
   then that user can craft arbitrary commands that may run as root. 
Vulnerability #3: CDE dtaction buffer overflow
   The dtaction utility allows applications or shell scripts that otherwise 
   are not connected into the CDE development environment, to request that CDE 
   actions be performed. 

   A buffer overflow can occur in some implementations of dtaction when a    
   username argument greater than 1024 bytes is used. 
Vulnerability #4: CDE ToolTalk shared library buffer overflow in TT_SESSION
   There is a vulnerability in some implementations of the ToolTalk shared 
   library which allows the TT_SESSION environment variable buffer to 
   overflow. A setuid root program using a vulnerable ToolTalk library, such  
   as dtsession, can be exploited to run arbitrary code as root. 

II. Impact
Vulnerability #1: ToolTalk ttsession uses weak RPC authentication mechanism
   A local or remote user may be able to use this vulnerability to run 
   commands on a vulnerable system with the same privileges of the attacked 
   ttsession. For this attack to work, a ttsession must be actively running on 
   the system attacked. The ttsession daemon is started whenever a user logs 
   in using the CDE desktop, or upon interaction with CDE at some future 
   point. 
Vulnerability #2: CDE dtspcd relies on file-system based authentication
   A vulnerable dtspcd may allow a local user to run arbitrary commands as  
   root. 
Vulnerability #3: CDE dtaction buffer overflow
   A local user may be able to exploit this vulnerability to execute arbitrary 
   code with root privileges. 
Vulnerability #4: CDE ToolTalk shared library buffer overflow in TT_SESSION
   A local user may be able to exploit this vulnerability to execute arbitrary 
   code with root privileges. 

III. Solution
Install appropriate patches from your vendor 

We recommend installing vendor patches as soon as possible and disabling the 
vulnerable programs until you can do so (or uninstalling the entire CDE 
package if not needed). Note that disabling these programs will severely 
affect the utility of the CDE environment. 
Appendix A contains information provided by vendors for this advisory. We will 
update the appendix as we receive more information. If you do not see your 
vendor's name, the CERT/CC did not hear from that vendor. Please contact your 
vendor directly.

SCO is investigating these vulnerabilities on SCO UnixWare 7. Other SCO 
products (OpenServer 5.0.x, UnixWare 2.1.x, Open Server / Open Desktop 3.0 
and CMW+) are not vulnerable as CDE is not a component of these releases. 
SCO will make patches and status information available at 
http://www.sco.com/security. 
Silicon Graphics, Inc.
SGI acknowledges the CDE vulnerabilities reported and is currently 
investigating. No further information is available at this time. As further 
information becomes available, additional advisories will be issued via the 
normal SGI security information distribution methods including the wiretap 
mailing list. 
Until SGI has more definitive information to provide, customers are 
encouraged to assume all security vulnerabilities as exploitable and take 
appropriate steps according to local site security policies and 
requirements.

Sun Microsystems, Inc.
Vulnerability #1: 
Systems running Solaris 7, 2.6, and systems running Solaris 2.5.1, 2.5, and 
2.4 installed with CDE are vulnerable if the UNIX authentication mechanism 
(default) is used. Sun recommends that sites using CDE use DES as the 
authentication mechanism. To set the authentication mechanism to DES, use 
the ttsession command with the '-a' option and specify 'des' as the 
argument (see ttsession(1) for more information). The use of DES 
authentication also requires that the system uses Secure NFS, NIS+, or 
keylogin. For more information about Secure NFS, NIS+, or keylogin, please 
see the System Administration Guide, Volume II. Information is also 
available at: 
http://docs.sun.com:80/ab2/coll.47.8/SYSADV2/@Ab2PageView/34908?DwebQuery=s

1.  Bulletin Topics


    Sun announces the release of patches for Solaris(tm) 7, 2.6, 2.5.1, 2.5,
    2.4, 2.3 (SunOS(tm) 5.7, 5.6, 5.5.1, 5.5, 5.4, 5.3), and SunOS 4.1.4,
    and 4.1.3_U1 which relate to various vulnerabilities in CDE and 
    OpenWindows.
        
    Sun recommends that you install the patches listed in section 4 
    immediately on systems running SunOS 5.7, 5.6, 5.5.1, 5.5, 5.4, 5.3,
    4.1.4, and 4.1.3_U1.
     
2.  Who is Affected
        
    Vulnerable:     SunOS 5.7, 5.7_x86, 5.6, 5.6_x86, 5.5.1, 5.5, 5.4, 5.3,
                          4.1.4, and 4.1.3_U1.
                 
    Not vulnerable: All other supported versions of SunOS.
    
3.  Understanding the Vulnerabilities
    
    The following vulnerabilities have been identified.


3.1 ToolTalk ttsession default authentication mechanism insecure


    The ToolTalk messaging utility, ttsession, allows independent 
    applications to communicate without having direct knowledge of 
    each other. The ttsession daemon is started automatically by 
    any program that needs to send or receive a ToolTalk message. It uses 
    AUTH_UNIX authentication by default. A local or remote attacker may 
    manipulate certain environment variables (which are used by ttsession 
    to determine how client messages are handled) to execute arbitrary 
    commands with the privileges of the running ttsession.
    
3.2 CDE dtspcd relies on file-system based authentication


    The CDE desktop subprocess control program (dtspcd) is a network
    daemon that accepts requests from clients to execute commands and
    launch applications remotely. By manipulating predictable files used 
    for authentication, a local attacker may exploit this vulnerability 
    to execute arbitrary commands and gain root access.


3.3 CDE dtaction buffer overflow 


    The dtaction utility allows applications or shell scripts, which are
    otherwise not connected into the CDE user environment, to request 
    CDE actions be performed. A buffer overflow vulnerability has been 
    discovered which may be exploited by a local attacker to execute 
    arbitrary instructions and gain root access.


3.4 CDE ToolTalk shared library buffer overflow in TT_SESSION


    A buffer overflow vulnerability has been discovered in the ToolTalk
    shared library which may be exploited by a local attacker to execute 
    arbitrary instructions and gain root access.
