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

1) An error within the handling of access controls of certain
resources can be exploited to gain access to otherwise restricted
Runtime Workbench resources.

2) An error within the "PFL_CHECK_OS_FILE_EXISTENCE" function in the
implementation of access restrictions can be exploited to enumerate
files on a system.

3) Input passed via the "TXVDestination" parameter to
TextContainerAdmin/administration_setup.jsp and the "ValueIndustry",
"ValueRegion", and "ValueExtension" parameters to
system_context_settings.jsp is not properly sanitised before being
displayed to the user. 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.

Successful exploitation of this vulnerability may require
administrative privileges.

4) Input passed e.g. via the "cc0Host", "cc0Id", "cc0Path",
"cc0Port", and "cc0Protocol" parameters to bcbadmSettings.jsp 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.

SOLUTION:
Apply SAP security notes 1567389, 1591146, 1591749, and 1585652.

PROVIDED AND/OR DISCOVERED BY:
