As a pentester, there are days when you'll get asked to look at the ordinary, and there are days that you'll be asked to look at something more challenging. This week was full of days that met the latter criteria and not the former. Whilst I can't share the scope, Portcullis was asked to examine a network implementation using the MPLS protocol and comment on the security or otherwise of it.

New Portcullis Labs Blog : Beware of Empty Paths https://labs.portcullis.co.uk/blog/beware-of-empty-paths/
Consider the case of a setUID binary that runs as root and allows the caller to execute certain other scripts and binaries from a given restricted directory. The Portcullis Labs team recently spotted such a case and I was aked to take a look to determine exploitablity. What follows is a short analysis of what I found.

The question I set myself was, what testing could we perform, under our normal terms of engagement which would contribute to the "blue team" i.e. the system administrators and developers better understanding what a real world attack actually looks like and whether their organisation is mature enough to deal with it. Firstly, let us consider what the kill chain actually consists of.

Portcullis is not new to the security market place, with the foundations of our company dating back to the mid-80s. It is fair to say that a lot has changed over the past three decades, but the fundamental principles of why organisations perform information security have remained constant. Private information needs to remain confidential. There is a need to trust the integrity of information. That information needs to be available when it is required. Our areas of expertise deliver this.
