Q: What types of systems are affected by “Shellshock” Bash?
A: Webservers and VPN servers are the primary systems at risk due to their externally facing nature; but almost all Linux/Unix systems and network appliances may be affected.
Q: Can DDI test for the vulnerability associated with “Shellshock” Bash vulnerability?
A: Yes! Fortra's Vulnerability Research team has developed a vulnerability test specifically for the issue and the test is available in the Frontline portal for client use. The test can be run as a single vulnerability test or as part of the full suite of tests.
Q: Why is DDI’s test more effective than those available for free on the internet?
A: Because the traffic pattern needed to completely test for this vulnerability require complex web-spidering and testing of all cgi-enabled pages, a commercial scanning solution is required. Almost everyone who has created a free-network-test has admitted that these sorts of single-probe tests for Shellshock are incomplete and often will false negative.
Another important factor to consider is that the free tools do not provide any level of support. As such, if you find that you have a system that is vulnerable to “Shellshock” Bug, you may have to do your own research or work with the vendor providing the system yourself to have the matter resolved. DDI clients are provided multiple levels of support, up to and including access to our vulnerability researchers and Personal Security Analysts (PSAs). This unprecedented level of support ensures that the business can secure their systems quickly and with greater assurance of accuracy implementing remediation efforts that positively impact the security of the system.
