DESCRIPTION:
Digital Security Research Group has reported multiple vulnerabilities
in SAP NetWeaver, which can be exploited by malicious users to conduct
script insertion attacks, manipulate certain data, bypass certain
security restrictions, and compromise a vulnerable system and by
malicious people to conduct cross-site scripting and cross-site
request forgery attacks.

1) Input passed via certain transactions to the BAPI Explorer is not
properly sanitised before being used. This can be exploited to insert
arbitrary HTML and script code, which will be executed in a user's
browser session in context of an affected site when the malicious
data is being viewed.

2) Input passed to the "instname" parameter in the VsiTestScan
servlet and "name" parameter in the VsiTestServlet servlet within the
Virus Scan Interface is not properly sanitised before being returned
to the user. This can be exploited to execute arbitrary HTML and
script code in a user's browser session in context of an affected
site.

3) Input passed to the "page" parameter in /SAP/BW/DOC/METADATA/ is
not properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

4) An error in the RSTXSCRP report when using transaction "sa38" can
be exploited to insert an arbitrary UNC path via the "File Name"
field.

5) An error in the TH_GREP report when handling certain SOAP requests
can be exploited to inject arbitrary shell commands via a "<STRING>"
parameter.

Successful exploitation of this vulnerability may allow execution of
arbitrary code.

6) The SPML service allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. create an arbitrary user if a
logged-in administrative user visits a malicious web site.

7) An error in the CTC service when performing certain authentication
checks can be exploited to gain access to user management and OS
command execution functionality.

Successful exploitation of this vulnerability may allow execution of
arbitrary code.

SOLUTION:
Apply fixes (please see the vendor's advisories for details).
