CVE-2014-6271 (“Shellshock”) and exploit PoC


September 26, 2014

By Andy Yang

(A little bit of background on this post – one of my colleagues, Norman Yue, posted something about the Internet being on fire to LinkedIn yesterday, regarding the bash bug. This blog post tries to explain a bit more about why exactly this is such a big issue, and also provides a proof-of-concept exploitation).

Firstly, the vulnerability itself. The actual vulnerability itself is amusing and unique, but otherwise, isn’t the magical everything-is-owned vulnerability that everyone makes it out to be. To paraphrase, if you are able to set an environment variable through the Bash shell, you can execute commands.

The interesting part is that this vulnerability may have existed for more than 20 years, in an application which is part of pretty much every Unix system since a long time ago. The vulnerable versions start from cpe:/a:gnu:bash:1.14.0 to cpe:/a:gnu:bash:4.3, which covers pretty much every Unix-based operating system available today (and by extension, a tremendous chunk of the Internet).

Nude Celebrity Scandal, Cloud Service Security and You!


September 04, 2014

Following the slew of private celebrity photos leaked earlier this week, both end-users and organisations are understandably concerned. Invariably, user confidence in the security of online services, and the confidentiality of any data stored, has been shaken by such leaks.

This is especially worrying for organisations, as more and more enterprise services move onto remotely hosted cloud platforms, which are now home to the corporate crown jewels (emails, commercially sensitive information, intellectual property etc).

The same security issues that appear to have caused the recent iCloud breaches typically affect these cloud platforms. From a security perspective, using a cloud system is effectively outsourcing and therefore should be treated as diligently as any other outsourcing arrangement.

According to Apple, the recent celebrity photo compromise occurred due to a “very targeted attack on user names, passwords and security questions” – in other words, social engineering password resets. Continue reading

A CIO’s Approach to Developing a Security Framework 101

One of the biggest questions we always get asked by CIOs and other senior business management in regards to Information Security and IT Risk Management is where to begin. Do you focus on purchasing security tools first, developing policies and standards or getting an audit done and working from the results of that audit?

From our experience, while all of the above can assist in some way, developing a framework about how you will think about your security position is the number one priority before you make a major investment in tools, your staff’s time or the costs of hiring consultants. You may find that a lot of the costs you estimated originally may not be needed. Continue reading

Achieving Comprehensive PCI DSS 3.0 Compliance

It’s not news that any entity that processes, transmits or stores account data, or can impact the security of cardholder data environment, is required to be compliant to PCI DSS 3.0. However, the business benefits of the security framework — a more secure network, protection of corporate brand and reputation, reduced risk of successful data breaches and network attacks — can easily be overshadowed.

Tripwire (a long time parter of Securus) combines the power of configuration control and deep file integrity monitoring (FIM) with comprehensive log and security information event management capabilities to help deliver continuous and unmatched PCI DSS compliance. The above white paper serves as a useful guide for security personnel who want to learn how Tripwire® Enterprise, Tripwire Log Center® and Tripwire IP360™ could assist in meeting PCI DSS requirements. Qualified Security Assessors (QSAs) might find this document useful as well, as it highlights the areas of the PCI DSS requirements that can be verified and met by those solutions.
