The Most Famous Vulnerabilities - Cross-Site Scripting (XSS)

It’s been a while since I wrote the previous episode of my blog series. If you are interested in Remote Code Execution, then I definitely recommend reading the previous part. So, here we are again, the moment has come for my final article about cross-site scripting (XSS). What is Cross-Site Scripting (XSS)? Usually, XSS vulnerability occurs when there are untreated inputs and bad cookie usage. So, please let me tell you about a case that happened in 2005 on Myspace. A MySpace user found an XSS vulnerability on the site, and he wrote a payload called „Samy Worm.” This payload was a...

GXHLGSL.txt file uploader botnet –Discovered by BitNinja FtpCaptcha

At the beginning of the year we released our brand-new FtpCaptcha module, and of course, we were so excited about receiving the first incidents. However, we didn’t think that the very first logs will be such eye-catching. We detected a not so well-known botnet, and we didn’t find an article about it (only a few forum topics), so we summarized everything that you need to know about it. Test the ability to upload a file This botnet is trying to upload a file named GXHLGSL.txt, which contains only this: TEST. If it was a vulnerability scanner, there would provide some description about it o...

The BitNinja mature WAF module

Nikolett Hegedüs
We love to talk about our Web Application Firewall (in short: WAF) module, since its’ complete makeover and upgrade. Before the WAF 2.0, we had a previous Web Application Firewall module that’s been completely redesigned: this was the reason why the new WAF module got a brand new name too: it’s called WAFManager now. But you’ll only see the module’s name like this in CLI, because we’re calling it WAF 2.0 most of the time. We put a lot of time and effort into shaping the upgraded, mature WAF module into an asset that is effective and customizable for our users. And why did we...

New BitNinja WAF Rules to Protect Against RCE Attacks

Your server’s safety is the number one priority for us, that’s why we have created two new BitNinja WAF rules which are already part of the safe minimum ruleset. They grant protection against the following vulnerabilities: Magento Remote Execution Protection Those who are using Magento and didn't apply the patch are vulnerable to RCE (remote code execution) attacks. By targeting the “Cms_Wysiwyg” controller, the attacker can take over the site and gain information such as customers’ credit card details. BitNinja will block requests sent to this controller which contain exact para...

Using server security scanners besides BitNinja: consequences, solutions

There are tons of paid/free cloud-based solutions or standalone applications available over the internet that allow the user to check a system’s security level. Depending on the need, people can choose from simple nmap through “blackbox” security assessment tools to a wide range of heavy-weight penetration testing tools. Our approach Here at BitNinja we think that security testing is the given organization’s responsibility. They should create a security-testing strategy and keep it up to date (often with help of an external partner, but it is very important that this is with the responsi...

The Most Famous Vulnerabilities - HTTP Parameter Pollution

In the previous blog article, we learned about SQL injection and how it works. If you read it then you will know that it belongs to the family of the most serious vulnerabilities. The next vulnerability is not going to be so serious, but it's worth taking care of. What is HTTP Parameter Pollution? The easiest way to introduce this vulnerability is to show the method that you have seen many times on websites or any other application that can be linked to the Internet at some level: redirection. A lot of websites use this technique to redirect from one website to another, or even within...

IT security misbeliefs – third IT security meetup by BitNinja

We like attending meetups because we believe that great ideas are created when we share our experience and knowledge. That’s why we decided to organize regularly an IT security meetup in our town, Debrecen. On 24th August, we held our third meetup and we are so happy that the number of the attendees is increasing. Not only did the cold beer and the delicious pizza attract participants, but so did the interesting topics we were discussing. The most recent topic was: IT security misbeliefs. 1.“If I’m using a strong password, everything is OK.” Most people believe that if they have a...

HackerOne – The Biggest Bug Bounty Platform

Our world would be insecure without bug bounty platforms. We don’t know who we can or cannot trust. If we find a vulnerability in a software as a white hat hacker, we would be afraid to report it to the software owners because we wouldn’t know what their reaction would be. Will they reward or sue? The same fear is present on the other side. As a software or IT company, we were worried about the agreement of the external penetration tester because we were afraid that the related information would come to a bad man. Fortunately, nowadays bug bounty platforms solve these problems. One of the b...

Attack Vector Miner – AI Technology for Detecting Zero-Day Attacks

Artificial Intelligence (AI) is spreading quickly in many industries, and we can gladly announce the Attack Vector Miner, one of our latest developments based on AI. But before we tell you more about that, let’s get a bit more familiar with AI. If you’re an AI expert, know everything about it, and are only curious about the Attack Vector Miner, just scroll down to the last paragraph. History of AI It’s not a new thing that machines “stole” people’s jobs; let’s think about the steam engine, the calculator, or the PC. But trends today show that we’d like to delegate even more tasks to mach...
