bash exploit code | Breaking Cybersecurity News | The Hacker News

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...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
