Security Advisories Relating to Symantec Products - Symantec Workspace 
Streaming XMLRPC Unauthenticated Access


May 12, 2014




CVSS2        Impact   Exploitability   CVSS2 Vector
Base Score
SWS Unauthenticated XMLRPC Access - High
7.9          10       5.5              AV:A/AC:M/AU:N/C:C/I:C/A:C


The management server for Symantec Workspace Streaming (SWS) does not properly 
handle external XMLRPC requests, which could potentially allow unauthorized 
access to restricted server-side data and server functionality.  A remote user 
could potential create a backdoor on the targeted server resulting in 
unauthorized privilege access.

Affected Products

Product              Version     Build    Solution(s)
Symantec Workspace   7.5.x and   All      Update to SWS ( 7.5 SP1)
Streaming            prior


Symantec Workspace Streaming server does not properly handle incoming HTTPS 
XMLRPC requests.   This could potentially allow a malicious individual 
unauthorized access to sensitive server-side files and functionality.  By 
submitting a sufficiently crafted XMLRPC request, a malicious user could place 
arbitrary code on the server that, if successfully crafted would create an 
unauthorized access point on the server.  This could potentially provide the 
malicious individual application-level access to the SWS server.

In a normal installation, a Symantec Workspace Streaming Server should not be 
accessible externally from the network environment which should limit this to 
an authorized but unprivileged network user attempt.  However, an external 
attacker able to successfully leverage network access by enticing an 
authorized user to visit a malicious site or click on a malicious HTML email 
could possibly further leverage that access to attempt to exploit this issue.

Symantec Response

Symantec product engineers have released SWS 7.5SP1 to resolve this issue. 
Symantec engineers reviewed and continue to review all product functionality 
to further enhance the overall security of Symantec Workspace Streaming. 

Symantec recommends customers apply the available update as soon as possible 
to avoid this type of issue.  Symantec is not aware of exploitation of or 
adverse customer impact from this issue.

Update Information

Symantec Workspace Steaming 7.5SP1 is available through Symantec File Connect.


Symantec Security Response has released IPS signature 27339 - “Symantec 
Workspace Streaming XMLRPC RCE" to help detect and block remote exploit 
attempts. Signatures are available through normal Symantec security updates.

Best Practices

As part of normal best practices, Symantec strongly recommends the following:

   Restrict access to administrative or management systems to authorized 
   privileged users.
   Restrict remote access, if required, to trusted/authorized systems only.
   Run under the principle of least privilege where possible to limit the 
   impact of potential exploit.
   Keep all operating systems and applications current with vendor patches.
   Follow a multi-layered approach to security. At a minimum, run both 
   firewall and anti-malware applications to provide multiple points of 
   detection and protection to both inbound and outbound threats.
   Deploy network- and host-based intrusion detection systems to monitor 
   network traffic for signs of anomalous or suspicious activity. This may aid 
   in the detection of attacks or malicious activity related to the 
   exploitation of latent vulnerabilities.
