If you use web applications that are developed with Linux, then you've probably heard of the Bash Shellshock vulnerability. The security bug allows the possibility of an attacker to gain access to your system in order to execute commands from environment variables. The Bash vulnerability made it to the headlines in 2017, a few months after the heartbleed vulnerability was announced.
The Bash Shellshock vulnerability was discovered by Stephane Chazelas and assigned to the CVE identifier cve–2014–6271. An analogous bug with similar characteristics was discovered by Tavis Ormandy and given the CVE identifier cve-2014-7169.
Unfortunately, the Bash Shellshock bug vulnerability is not limited to Linux environments; it can affect versions of UNIX and Mac OS X as well. Through the Shellshock bug an attacker can send commands to your server through a HTTP request which will then be executed by the Web server's operating system. If your system is compromised, not only can the Shellshock bug allow a hacker to run unintended code remotely, it could also allow one of these outside agents to gain access permission to one web server or even to dive deeper into other network computers where your data could be compromised on a bigger scale.
In order to stay ahead of this and other web security weaknesses, employing a tool like Netsparker's web vulnerability scanner will help you proactively manage your web security. Netsparker's on premises or cloud-based scanner can help you identify potential vulnerabilities in your web environment, which is crucial now more than ever.
More than 70% of websites today are vulnerable--don't let yours be one of them.
Not only is Netsparker's web application security scanner able to automatically detect whether your web application is vulnerable to the Bash Shellshock bug, but it is capable of much more. Once a vulnerability is detected, Netsparker's dead accurate Proof-Based Scanning™ technology eliminates false positives. In short, it confirms the vulnerabilities automatically so you don't have to.
In addition to identifying potential Shellshock bug vulnerabilities, Netsparker is able to identify and report thousands of other web application vulnerability variants, such as SQL injection and Cross-site scripting (XSS). Netsparker can also detect security vulnerabilities that are listed on the OWASP Top 10 list of most critical security flaws. Netsparker's robust web scanning technology is also able to understand, crawl and attack all kinds of web applications, including modern and custom built HTML5, Web 2.0 and Single Page Applications (SPAs), regardless of the platform and technology on which they are built.
It's no secret that Netsparker has an industry edge due to its dead accurate Proof-Based Scanning™ technology, which provides users with a reliable proof of exploit. This eliminates the need to double check scan results because there are no false positives. In turn, this saves your IT team valuable time that can be directed toward vulnerability mitigation. Netsparker is also readily scalable and is able to run scans on 100s or 1000s of websites at a moment's notice. It can also be integrated into your existing web infrastructure, SDLC and DevOps environments seamlessly.
Netsparker’s efficient web security scanner can help support your IT team’s work through prompt detection of issues. Let Netsparker detect all forms of SQL injections, Cross-site Scripting (XSS) and other exploitable vulnerabilities while you focus your time on prevention and remediation. By identifying web application vulnerabilities early, you can work to protect against them.
