GNU Bash through 4.3 bash43-026 does not properly parse function definitions in the values of environment variables, which allows remote attackers to execute arbitrary commands 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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271, CVE-2014-7169, and CVE-2014-6277.

Security readout for executives and security teams

CVE-2014-6278 is a Bash parsing flaw in environment-variable function definitions. In certain integrations, an external input can cross into an environment variable and later be processed by Bash, allowing attacker-controlled commands to run. The CVE describes remote vectors including Apache CGI, OpenSSH ForceCommand, and DHCP-client script paths. Highest exposure is where Bash is invoked after untrusted data is placed into the environment. The CVE specifically names Apache mod_cgi/mod_cgid, OpenSSH sshd ForceCommand, DHCP client scripts, and similar privilege-boundary environment handoffs. Product coverage is broad but the bundle does not enumerate exact affected CPEs. High priority for legacy or exposed Unix/Linux environments. This is an older Shellshock-family issue, but the impact is full command execution when reachable patterns exist. Executives should require proof of patch coverage and targeted exposure review, not just a general statement that Shellshock was addressed years ago. Mitigation focus: Apply vendor Bash security updates for each operating system, appliance, and bundled product.; Review Oracle, IBM, HP, Check Point, SUSE, and JVN advisories for product-specific guidance.; Prioritize systems exposing CGI, forced SSH commands, or DHCP hook scripts that invoke Bash..

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
