The new Oracle Java arbitrary code execution vulnerability has not only hit many news wires and social media outlets, but many victims as well, and it has been incorporated into several exploit kits. This critical vulnerability, as documented in IntelliShield alert 27845, could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system with the privileges of the user. If the user has administrator privileges, the attacker could completely “own” the system.
A fix is currently not available.
Update: Oracle released a software update (JDK7 update 11) that fixes this vulnerability. The update is available on their website. If you disabled Java in the Java Control Panel, you will need to manually re-enable it after installing the patch by using the check box in the Security tab of the Java Control Panel. Oracle’s security advisory and JDK7 update 11 release notes includes more information about the patch.
The exploit is now found in several exploit kits!
There are many reports that the vulnerability is being “exploited in the wild”. Not only is the exploit publicly available, but it has been incorporated into exploit kits such as Blackhole, Cool, and Nuclear Pack. Exploit kits make it easy for criminals to spread malicious software using exploits that take advantage of well-known and new vulnerabilities. New exploit kits are loaded with some of the most dangerous zero-day exploits (including this one) and other features, which allow criminals to increase their profits.
The impact to the public is huge! Java is used by millions of users around the world. It is used in Microsoft Windows, Apple’s Mac OS-X, and Linux systems, as well as many mobile devices. Read More »

I have been coaching youth sports for the past seven plus years now and one of my common mantras when speaking to the girls and boys each season is that “we will win as a team and lose as a team.” In other words, I will never tolerate one player acting selfishly enough to think he or she is above everyone else on the team. I strive to instill the objective that we will collectively pool our talents for the betterment of the team. We use this approach because each boy and girl, believe it or not, brings with himself or herself a unique set of abilities and strengths with which the entire team will benefit.
So why should you care about my coaching philosophies? Read More »

Is the product safe to use? I have been asked this question on occasion in a non-technical sense and maybe you have too. In a technical context, I could frame the question as “Are the online services and underlying technologies supporting my services safe?” A continuous effort must go into substantiating the preferable answer (“Yes”) that we are looking for, both prior to and after releasing a product or service into the wild. Security Intelligence Operations (SIO) includes a team of network security experts that form the Security Technology Assessment Team (STAT). They provide security assessment expertise across Cisco’s product and services organizations. In this article, I elaborate on their role and how they complement product and services organizations at Cisco in helping to protect you, our customer.
In the not-so-distant past it used to be that the majority of notoriety around product security was focused more around physical aspects. For example, a manufacturer announces a product recall about a defect (i.e. vulnerability) that could cause potential physical harm or worse. Fast-forward to today where computing devices and associated Internet plumbing comprise an entirely distinct category of product security needed. Within that category, I would also suggest that services and the underlying supporting infrastructure would also fall into this category in the ongoing quest for achieving network security. I think that this quote from a U.S. government hearing underscores the value of that quest as well.
“When we bring in new technologies, we bring in new exposures and new vulnerabilities, things we really haven’t thought about. It takes a little while before we understand it, and after a while we begin to secure it. But our mindset needs to change. This is not the same as industrial technologies or new ways of doing aircraft or cars. These technologies are global and they expose us globally, literally within milliseconds.”

Business units and quality assurance groups at Cisco apply multi-level security processes throughout the development of products and services to ensure that security is embedded into everything that is ultimately delivered to customers. For example, Cisco’s secure development life cycle (SDL) provides a highly effective process in detecting and preventing security vulnerabilities and improving overall system quality. Cisco SDL has several elements that include, but not limited to, source code analysis and white box testing that feed into the security posture of a product or service. Cisco has a security advocates program, a virtual community of people who understand network security and secure product development (and testing) and who can share and evangelize that knowledge with their peers, their colleagues, and their management.

Create community. Drive cross company collaboration. Raise the corporate security consciousness. Educate! These were the major themes present at the synergistic 5th annual Cisco SecCon held December 5-6, 2012, at Cisco’s corporate headquarters in San Jose, CA. The senior leadership team in the Security and Government Group had a clear and present message for the Cisco Engineering community: Security is the differentiator for Cisco! Building and developing our corporate security awareness and driving it into our DNA is part of what makes Cisco—a company dedicated to continuous improvement—unique as a top industry leader.
The message is clear: security must be pervasive in every aspect of every product we design, develop, and deploy. It’s what our customers expect, and SecCon is one of the major delivery vehicles for creating a unified front within the engineering community as part of Cisco’s evolution towards the Internet of Everything. The more the world becomes interconnected, the more important it is that product designers, developers, testers, and implementers are aware and educated about the importance of the security mindset. How we think about security dictates how we act. This is something the Cisco leadership team is keenly aware of, and their intent to mature security capabilities and features into our entire product line is evident as they work to bring together industry security advocates to drive change and continuous improvement at the annual SecCon conference.

Secure software is a hot topic these days and many people have ideas about what should be done to achieve it. For years, the focus of many software vendors was on security features. Add a firewall. Add SSL to secure data flows. Positive security features are great, but they don’t do much to address every potential security issue that result from insecure code.
At this year’s Cisco SecCon conference, Bryan Sullivan, Microsoft’s Security Program Manager, addressed the issue of writing secure code with a diagram like the following:
His point is that there is much more work to do in securing all the features of a product than simply writing the security features. Writing security features, although important, is only 10% of the workload of creating secure code. The other 90% of the coding work is meant to ensure that all non-security codebase is secure. This includes input validation, output encoding, and overflow defense.
These practices are part of software quality, and they don’t usually appear on a feature list and often fail to appear on customer requirements lists. Customers don’t often ask for things such as:
- This product should be free of cross-site scripting vulnerabilities
- This product shouldn’t have client-side security validation that can be bypassed by a determined attacker
- This product shouldn’t store my passwords or key data in plain text files might be leaked
