Fwd: Security (or lack of) at Number26 2017-01-09 No Comments

Hi! I would like to share a talk that I attended at 33c3. It’s about a company with a banking license and accounts with actual money. Some people downplay these issues as “yeah, but the issues were fixed” and “every major bank probably has something like this”. I would like to reply: With a bit […]

Comment vulnerability in WordPress 4.2 2015-04-27 No Comments

Hanno Böck tweeted about WordPress 4.2 Stored XSS rather recently. The short version is: if an attacker can comment on your blog, your blog is owned. Since the latest release is affected and is the version I am using, I have been looking for a way to disable comments globally, at least until a fix […]

Apache AddHandler/AddType vulnerability: Magento <1.9.1 affected 2015-04-26 No Comments

I ran into an example of a web application vulnerable to Apache AddHandler/AddType misconfiguration by chance today. The releases notes of Magento Community Edition 1.9.1 point to a remote code execution vulnerability. Interestingly, the section Determining Your Vulnerability to the File System Attack is precisely a switch from AddHandler to SetHandler. Fantastic! Let’s see if […]
