Bash Exploit 
• This still works with the latest bash update 
• (X='() { (a)=>' bash -c "echo ls /etc; cat echo") 
• As does this: 
• env X="() { :;} ; echo busted" /bin/sh -c "echo stuff” 
• The following commands will implement a signature in ‘Report Only’ mode in our 
DefensePro. 
• 
• dp signatures-protection filter basic-filters user create ERT-bash2-CVE-2014-6271 -p 
tcp -c x28x29x20x7b -ct "Normalized URL" -ce "Case Sensitive" -dp http 
• dp signatures-protection filter advanced-filters user create group_ERT-bash2- 
CVE-2014-6271 ERT-bash2-CVE-2014-6271 
• dp signatures-protection attacks user create 0 -n ERT-bash2-CVE-2014-6271 -f 
group_ERT-bash2-CVE-2014-6271 -am 0 
• dp update-policies set 1 
• 
• The customer should carefully inspect false positive rates of this signature and only 
afterwards to move it to ‘Block and Report’ mode.
