Bash bug | Breaking Cybersecurity News | The Hacker News

The year is about to end, but serious threats like  Shellshock is " far from over ". Cyber criminals are actively exploiting this critical GNU Bash vulnerability to target those network attached storage devices that are still not patched and ready for exploitation. Security researchers have unearthed a malicious worm that is designed to plant backdoors on network-attached storage (NAS) systems made by Taiwan-based QNAP and gain full access to the contents of those devices. The worm is spread among QNAP devices, which run an embedded Linux operating system, by the exploitation of the GNU Bash vulnerability known as ShellShock or Bash, according to security researchers at the Sans Institute. QNAP vendor released a patch in early October to address the flaw in its Turbo NAS product, but because the patches are not automatic or easy to apply for many users, so a statistically significant portion of systems remain vulnerable and exposed to the Bash bug . Sh

A recently discovered hole in the security of the Bourne-Again Shell (bash) has the majority of Unix/Linux (including OS X) admins sweating bullets. You should be, too--attackers have already developed exploits to unleash on unpatched web servers, network services and daemons that use shell scripts with environment variables ( this can include network equipment, industrial devices, etc .) Jaime Blasco , AlienVault Labs Director, gives a good explanation of the exploit in this blog post . And, the video below gives you a quick overview of how AlienVault Unified Security Management (USM)  can detect malicious traffic on your network trying to locate and exploit this vulnerability. Basically, this vulnerability allows an attacker to execute shell commands on a server due to an issue in how bash interprets environment variables (such as "cookie", "host", "referrer"). Exploiting this allows an attacker to run shell commands directly. Once they have access to run shell comm

A Critical remotely exploitable vulnerability has been discovered in the widely used Linux and Unix command-line shell, known as Bash , aka the GNU Bourne Again Shell , leaving countless websites, servers, PCs, OS X Macs, various home routers, and many more open to the cyber criminals. Earlier today, Stephane Chazelas publicly disclosed the technical details of the remote code execution vulnerability in Bash which affects most of the Linux distributions and servers worldwide. REMOTELY EXPLOITABLE SHELLSHOCK The vulnerability (CVE-2014-6271) affects versions 1.14 through 4.3 of GNU Bash and being named as Bash Bug , and Shellshock by the Security researchers on the Internet discussions. According to the technical details, a hacker could exploit this bash bug to execute shell commands remotely on a target machine using specifically crafted variables. " In many common configurations, this vulnerability is exploitable over the network, " Stephane said. This 22-ye
