Qualys Web Application Scanning (WAS) has added a new detection that will provide the most comprehensive identification of the Shellshock vulnerability across all of your web applications. With the ability to crawl and identify even non-standard directory locations within your web application, Qualys WAS will deliver the most accurate, detailed and reliable form of automated ShellShock detection for web applications. ShellShock is a wide-reaching vulnerability with multiple attack vectors. If you use any form of Linux or Unix machines in your network you are likely to have the vulnerability.  We have released a new QID (150134) for WAS specifically for this purpose.

Update5: We have added a new profile in Qualys VM that uses the advanced crawling capabilities of Qualys WAS to detect Shellshock in CGI programs. WIth this profile you get better coverage than with the current QID 13038. There is a good explanation of how to setup the profile at our blog post: Custom Option Profile To Detect Bash Shellshock

Check it out. I am looking forward to your feedback.

Update4: Our web application scanner (WAS) has been updated with a Shellshock detection. Look for QID 150134 in your WAS scans. Differently from our VM detections, WAS has an advanced crawler with JavaScript capabilities which allows you to cover the entire website and probe for CGI scripts susceptible to Shellshock on a much wider range.

Update3: The last couple of days have been filled with new information on Shellshock. Today for example we had news on a first botnet that is using Shellshock, illustrating the speed  We are working on adding checks into other relevant areas, such as our Web Application Scanner. Stand by for more news on that. In the meantime we have collected a number of community posts on how to use QualysGuard to detect and report on Shellshock.
