Apache Server - Remote Code Execution (Shellshock - CVE-2014-6271) (CVE-2014-6271)

Apache server is affected by a Remote Code Execution vulnerability, located in the bash environment variables. The root cause of this vulnerability consists in using a version of the bash binary before 4.3 which processes trailing strings after function definitions. Therefore, an unauthenticated remote attacker could use the Common Gateway Interface (CGI) and a crafted HTTP header like User-Agent to to execute commands on the server.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware, or pivot to the internal network.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

Upgrade bash utilitary to the latest version.
