The risk of Spell Checking

Did you know that input fields on a web form support spell checking by default in many web browsers? This is a feature of the browser that can help catch errors early for the end user. Recently, some testers found that some data may be leaked during the spell checking function to 3rd parties. Here is a reference article describing this: https://www.darkreading.com/application-security/spellchecking-google-chrome-microsoft-edge-browsers-leaks-passwords The first point to make here is this is … [Read more...] about The risk of Spell Checking

Input validation is less about specific vulnerabilities

Security takes a layered approach to reduce the risk to our organization. Input validation is the perfect example of one of these layers. In most cases, input validation is 1 factor in a multi-pronged approach to protecting against common vulnerabilities. Take any course on secure development and they will, or should, mention input validation as a mitigating control for so many vulnerabilities. You might notice that it always comes with a but. Use input validation, but also use output … [Read more...] about Input validation is less about specific vulnerabilities

Is encoding really encoding if it is escaping?

The title might be confusing, let's see if we can clear it up. I saw an article the other day that was giving a comparison between encoding, encryption and hashing. There was a statement made that basically said: Encoding has no security purpose. I thought this was interesting because when training on security topics we mention encoding for specific use cases. For example, when we discuss Cross-Site Scripting, the answer is output encoding. I want to clarify that I agree with the statement … [Read more...] about Is encoding really encoding if it is escaping?

Log4J – Reflection and Progression

Open any social media platform or pull up any mainstream media and undoubtably, you have seen many posts/articles talking about the log4j vulnerability. If you haven't seen this, here is a quick link to catch up https://snyk.io/blog/log4j-rce-log4shell-vulnerability-cve-2021-4428/. This post is not going to be about log4j, nor is it going to go into any of the details the thousands of others articles out there would go through. Instead, I want to discuss this at a higher level. Log4j is just an … [Read more...] about Log4J – Reflection and Progression

Proxying localhost on FireFox

When you think of application security testing, one of the most common tools is a web proxy. Whether it is Burp Suite from Portswigger, ZAP from OWASP, Fiddler, or Charles Proxy, a proxy is heavily used. From time to time, you may find yourself testing a locally running application. Outside of some test labs or local development, this isn't really that common. But if you do find yourself testing a site on localhost, you may run into a roadblock in your browser. If you are using a recent version … [Read more...] about Proxying localhost on FireFox

Chrome is making some changes.. are you ready?

Last year, Chrome announced that it was making a change to default cookies to SameSite:Lax if there is no SameSite setting explicitly set. I wrote about this change last year (https://www.jardinesoftware.net/2019/10/28/samesite-by-default-in-2020/). This change could have an impact on some sites, so it is important that you test this out. The changes are supposed to start rolling out in February (this month). The linked post shows how to force these defaults in both FireFox and Chrome. In … [Read more...] about Chrome is making some changes.. are you ready?
