Perfect Persistence via Package Manager

What do most Linux machines come pre-installed with? Package managers. Community member aringo is taking advantage of this with two new modules for setting up persistence via yum and apt. Once you get privileged access you can now easily set up a method to get back in using a tool that has a high likelihood of being present.

Double Dose of DoubleTap

If you read last week’s wrap-up, you might be having a case of deja vu. Our own wchen-r7 has added a second module exploiting the Ruby on Rails “DoubleTap” vulnerability. This version takes advantage of the method Rails uses to generate secrets to get code execution. Be sure to check it out!

Spring Open Some Files

A new module has been added by RootUp that exploits a directory traversal vulnerability in Spring Cloud Config. The module crafts a special request to display the contents of files on the host machine. jhart-r7 noted that there are ~3300 instance of Spring Cloud listening in the world. Hopefully they’re patched up!
