Countdown to GDPR — Reduce your Risk

First discussed in the 1990s and turned into law last year, the EU’s General Data Protection Regulation (GDPR) finally goes into effect in May 2018, imposing strict requirements on millions of businesses and subjecting violators to severe penalties.

The complex regulation is of concern not just to European businesses. It applies to any organization worldwide that controls and processes the data of EU citizens, whose privacy the GDPR is meant to protect.

A recent PwC survey found that more than half of U.S. multinationals say GDPR is their main data-protection priority, with 77% of them planning to spend $1 million or more on GDPR readiness and compliance.

“The GDPR is putting data protection practices at the forefront of business agendas worldwide,” Steve Durbin, Information Security Forum’s managing director, wrote recently.

In other words, it’s crunch time for companies that fall within the GDPR’s broad scope and that haven’t completed their preparations to comply with this regulation. Gartner estimates that about half of organizations subject to the GDPR will be non-compliant by the end of 2018. You don’t want to be in this group of laggards.

The Stack Clash

What is the Stack Clash?

The Stack Clash is a vulnerability in the memory management of several operating systems. It affects Linux, OpenBSD, NetBSD, FreeBSD and Solaris, on i386 and amd64.  It can be exploited by attackers to corrupt memory and execute arbitrary code.

Qualys researchers discovered this vulnerability and developed seven exploits and seven proofs of concept for this weakness, then worked closely with vendors to develop patches. As a result we are releasing this advisory today as a coordinated effort, and patches for all distributions are available June 19, 2017. We strongly recommend that users place a high priority on patching these vulnerabilities immediately.

Dynamic Questionnaire: Accelerate Quick and Efficient Responses with Question Gating

As you roll out Security Assessment Questionnaire to your vendors and internal stakeholders, it is necessary to avoid lengthy questionnaires containing many sections with questions that are not relevant to their area of work. It is important that respondents don’t get overwhelmed and spend a lot of time and effort in sifting through all the questions deciding for themselves whether a section or a question is relevant or applicable to them. Invariably, this results in delays in getting their responses back to you.

The latest version of Security Assessment Questionnaire enables you to use a gating mechanism for controlling the flow of your questionnaire. You can now decide which questions or sections a respondent can see, based on his response to a question or a combination of questions. This makes it easier for respondents to see and respond to only relevant sections and questions thereby making the entire exercise more time-efficient for them. It is also easier for you to analyze all the consolidated responses.

Lessons Learned from SQL Injection Fix in Joomla 3.7.0

The Joomla community recently patched a SQL injection vulnerability introduced in Joomla 3.7.0. The article reporting this vulnerability explains how to identify the vulnerability (which was discovered via static code analysis) and how to craft an attack, e.g.

http://example.com/joomla/index.php?option=com_fields&view=fields&layout=modal&
list[fullordering]=exploitation_code

After reviewing the description of the vulnerability, I wondered whether an automated web application scanner, known as a DAST (Dynamic Application Security Testing) tool, could identify an instance of this vulnerability without digging into the source code.

Samba Vulnerability CVE-2017-7494

On Wednesday, the Samba Team patched a vulnerability that exists in all versions of Samba including and after version 3.5.0. Exploitation of this vulnerability could result in remote code execution on the affected host.

Samba is used to provide SMB and CIFS services for Linux systems, and is pervasive in both enterprise and consumer products. While the Samba Team is providing patches for the latest versions (4.4.x and higher), some Linux vendors, such as RedHat and Ubuntu, are providing patches for older versions of Samba if they are used in a supported version of the OS. The Samba Team may also release patches for older versions of Samba.
