Security Advisories Relating to Symantec Products - Symantec Workspace
Streaming XMLRPC Unauthenticated Access
May 12, 2014
CVSS2 Impact Exploitability CVSS2 Vector
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.
Product Version Build Solution(s)
Symantec Workspace 7.5.x and All Update to SWS 126.96.36.1999 ( 7.5 SP1)
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 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.
Symantec Workspace Steaming 7.5SP1 is available through Symantec File Connect.
Symantec Security Response has released IPS signature 27339 - âSymantec
Workspace Streaming XMLRPC RCE" to help detect and block remote exploit
attempts. Signatures are available through normal Symantec security updates.
As part of normal best practices, Symantec strongly recommends the following:
Restrict access to administrative or management systems to authorized
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.
Symantec thanks Andrea Micalizzi (rgod) working through HPâs Zero Day
Initiative(ZDI) for reporting this and ZDI for working with us as we addressed
