The dangers of type coercion and remote management plugins | Jon Cave

http://joncave.co.uk/2013/03/dangers-of-type-coercion-and-remote-management

The dangers of type coercion and remote management plugins. ManageWP, InfiniteWP, and CMS Commander. These three services share the same code base for the client plugin (I believe it’s originally authored by ManageWP and used by the other two with some tweaks) and so they were all vulnerable to a signature bypass that would allow remote code execution. An incoming message is authenticated by. Signature is the MAC sent with the message. Data is part of the message. Function is always a string, but if.

I captured the flag! | Jon Cave

http://joncave.co.uk/2012/08/i-captured-the-flag

I captured the flag! Last week, Stripe launched their second capture the flag competition. Unlike the CTF they held in February, this version involved web-based vulnerabilities and exploits instead of lower-level problems. Also unlike the first CTF run by Stripe I was able to complete the last level and capture the flag! I know that there are many write-ups of all of the different levels already, so I just want to talk about the technical details of my favourite level. Route requires authentication it do...

To be a writer - Welcome to Connie Hullander's Blog. The blog about learning to be an author. Wednesday, May 28, 2014. For the last few days I've been tracking down information on an old crime – a tragedy comparable to the familicides we hear of all too often these days. The story of what happened afterwards is unusual enough that I want to use it as the basis of a novel. For the victims, it's too awful to publicize. For the viewer, it's horribly depressing. I think I'll watch cartoons instead. It's a we...
