CVE-2014-6271

CRITICAL KEV NUCLEI LAB

Apache mod_cgi Bash Environment Variable Code Injection (Shellshock)

Title source: metasploit
STIX 2.1

Exploitation Summary

CVE-2014-6271 is actively exploited and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, added January 28, 2022. EIP tracks 137 public exploits from researchers including Metasploit, Hacker Fantastic, Bernhard Mueller, including a Metasploit module exploits/multi/http/cups_bash_env_exec. A Nuclei detection template is also available.

AI-analyzed exploit summary This Metasploit module exploits CVE-2014-6271 (Shellshock) in Qmail by injecting malicious environment variables via the SMTP MAIL FROM field, leading to remote code execution if /bin/sh is linked to Bash.

Description

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.
