Steal all the passwords

I talk a lot about Authenticated Code Execution, but of course that's not the only thing that authenticated access can get you. This week's update comes with a couple of modules for using known credentials to extract more credentials. The first is for Symantec Brightmail, an email filtering gateway that comes with a management interface for administrators. Any account with read access is allowed to look at the encrypted LDAP credentials stored in Brightmail. Fortunately for us, the encryption is reversible and the system also kindly uses a known key. The second module is for Canon multi-function printers, because of course your printer needs to store a bunch of plaintext passwords; I mean, why wouldn't it? This one also requires authentication, but it's a printer, so of course there's a default that no one ever changes.

Payload options in jobs output

To see the stuff running in the background, msfconsole has a jobs command. There are some pertinent pieces of info you usually want to see in that display, but a console interface makes it kinda tough to view it all because of the limited column width. A recent feature, the ability to control the URI a reverse_http payload calls back to with the LURI option, puts extra pressure on that limited space. To make that a little easier, payload options are now all condensed into a single column, so instead of seperate LPORT, LHOST, and LURI columns, you just have "Payload opts":

msf exploit(ie_cbutton_uaf) > jobs


  Id  Name                                       Payload                           Payload opts
  --  ----                                       -------                           ------------

## <span>Gifts that keep on giving</span>

Shellshock is one of my favorite bugs of all time. It's simple to exploit, results in RCE, and is in a thing that everyone takes for granted. The latest incarnaiton of it is in IPFire, an open source Linux firewall, but I'm sure we'll see it again.
