Hey Thomas, you actually kind of started me in web app security. You interviewed me for Matasano, and when I told you I didn't have experience with web apps, you overnighted me a copy of The Web Application Hacker's Handbook. You ultimately made me an offer, but after difficult deliberation, I ended up joining iSEC. Thanks again for sending me the book! It's been tremendously helpful.
I 100% agree that people shouldn't design systems this way, and if I were still a pentester, I'd write it up if I found it. But if the implementation correctly checked the domain and verified it was https:// https:// (and maybe did some cert pinning), I couldn't justify anything higher than low severity.
We've kind of gone way into the weeds on my made up example, but it was initially in response to this:
>> > I think the author is partially at fault for repeatedly failing to communicate the issue clearly.
> I disagree. The first sentence of the report includes "HTTP", "man in the middle attack" and "store.steampowered.com" ... If that isn't clear to someone, they are not sufficiently trained to triage vulnerability reports.
I just disagree with the idea that any plaintext HTTP request in an app inherently is a vulnerability.
- tptacek 7y agoWhat a nice comment! And in a thread where I am definitely not at my best (it's been an allergy migraine kind of day). This made my evening; thank you. iSEC was a great team! I'm more of an absolutist about HTTPS than you are, though. :) I feel like every once in awhile I need to plow face-first into the brick wall of a friendly comment like this just as a signal to dial it back a bit. It's been a challenging couple weeks. I'll dial it back a bit! Thanks again.
