What is CVE-2014-6278?
The GNU Bash shell prior to version 4.3.26 (bash43-026) has a command injection vulnerability. This flaw arises due to improper parsing of function definitions from environment variables, enabling remote attackers to execute arbitrary commands. This can occur in various scenarios, such as through OpenSSH's ForceCommand feature, Apache's mod_cgi, and certain DHCP clients. The vulnerability results from an incomplete fix related to previous CVEs, demonstrating a serious flaw in Bash's handling of external inputs.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
