Shellshock, also known as Bashdoor
Vulnerability details for CVE-2014-6271
cvedetails.com/cve/CVE-2014-6271/
A flaw in Apache web server allows me to have Interaction via remote-code execution. The local web address "10.0.0.30:6521" which I chose to use in order to set this up ethically could be replaced with any web server address set up on the attackers machine; likewise, as shown below the malicious web site will generate a reverse shell payload, execute it on a remote system, and get a shell. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit vulnerabilities. This vulnerability CVE-2014-6271 exploits a flaw in Bash, and multiple modules in the Apache HTTP Server and allows for arbitrary code execution.
This is the environment that I crafted.
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.
