Regulators advise FIs to address 'Shellshock' vulnerability ASAP

The vulnerability could allow an attacker to execute malicious code on the widely used Bash software tool and gain control over a targeted system.

Financial institutions should quickly address the "Shellshock" vulnerability by applying patches to their Bash software, the Federal Financial Institutions Examination Council said Friday.

Bash, or Bourne-again Shell — a common software tool found in most UNIX, Linux, and Mac OS X operating systems, and which also may be installed on Windows servers — is used to execute a sequence of commands.

The Shellshock vulnerability could allow an attacker to execute malicious code on Bash and gain control over a targeted system. The pervasive use of Bash and the potential for this vulnerability to be automated presents a material risk.

FIs and their service providers should assess the risk to their infrastructures and execute mitigation activities with appropriate urgency, FFIEC said. Additionally, FIs should identify all servers, systems, and appliances that use the vulnerable versions of Bash and follow appropriate patch management practices.

Financial institutions relying on third-party service providers should ensure those providers are aware of the vulnerability and are taking appropriate mitigation action.
