The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications. The Open Web Application Security Project (OWASP) is a 501c3 not-for-profit worldwide charitable organization focused on improving the security of application software. Our mission is to make application security visible, so that people and organizations can make informed decisions about true application security risks. Everyone is free to participate in OWASP and all of our materials are available under a free and open software license. The more information provided the more accurate our analysis can be.
If the submitter prefers to have their data stored anonymously and even go as far as submitting the data anonymously, then it will have to be classified as “unverified” vs. “verified”. There are three new categories, four categories with naming and scoping changes, and some consolidation in the Top 10 for 2021. Globally recognized by developers as the first step towards more secure coding. If you read through the above, you may be wondering what changed between this revision and the previous.
Upcoming OWASP Global Events
We plan to calculate likelihood following the model we developed in 2017 to determine incidence rate instead of frequency to rate how likely a given app may contain at least one instance of a CWE. This means we aren’t looking for the frequency rate (number of findings) in an app, rather, we are looking for the number of applications that had one or more instances of a CWE. We can calculate the incidence rate based on the total number of applications tested in the dataset compared to how many applications each CWE was found in.
• A8 – Cross-Site Request Forgery (CSRF), as many frameworks include CSRF defenses, it was found in only 5% of applications. A10-Unvalidated Redirects and Forwards, while found in approximately in 8% of applications, it was edged out overall by XXE. In general sanitization is a protection from this class of attacks, but a better one is a safe API.

Although I feel that a few of the changes are a little confusing to me, it’s not the case that I considered the 2013 list perfect either. Some items from 2013 were consolidated, specifically around access control. And other things were added, specifically #4 XML External Entities, #8 Insecure Deserialization, and #10 Insufficient Logging.
The latest OWASP Top 10 represents the first update to the vulnerability ranking since 2013. XSS, or cross-site scripting has fallen a good distance in the 2017 revision of the OWASP Top Ten. The reason for this is that it’s so often cited as a security vulnerability, the likelihood of people making mistakes that render their application vulnerable has declined a good deal.

This will help with the analysis, any normalization/aggregation done as a part of this analysis will be well documented. The analysis of the data will be conducted with a careful distinction when the unverified data is part of the dataset that was analyzed. Irresponsibly, I also will cop to the fact that my understanding of the exploitability of this sort of vulnerability also never computed for me, especially relative to the amount it was talked about. I think it’s prior prominence had a lot to do with CSRF being a conveniently simple acronym.
It’s still important to know the details of how these risks work. We will explore XML External Entities (XXE), Cross-Site Scripting (XSS) and Insecure Deserialization. At a high level, we plan to perform a level of data normalization; however, we will keep a version of the raw data contributed for future analysis. We will analyze the CWE distribution of the datasets and potentially reclassify some CWEs to consolidate them into larger buckets. We will carefully document all normalization actions taken so it is clear what has been done. AppSec Starter is a basic application security awareness training applied to onboarding new developers.
Npm’s recent inclusion of an audit tool is a step in the right direction. And when you can’t update regular, check on the security content of new updates in your dependency graph. 2017 and 2013 version mapping relationship see the following figure. Compared to the 2013 version, some of the risk factors also have some changes. Following a lengthy gestation, the Open Web Application Security Project (OWASP) Top 10 is finally here. And while the de facto application security standard now includes three new categories, injection has maintained its position at the top of the risk chart in 2017.
- It’s somewhere between possible and likely that this happened in the past, but because I was authoring WordPress Security with Confidence at the time, I paid much more careful attention to the whole process.
- What this means is one where even if a use submits known bad data, nothing bad can possibly happen via that method.
- At a high level, we plan to perform a level of data normalization; however, we will keep a version of the raw data contributed for future analysis.
- At a bare minimum, we need the time period, total number of applications tested in the dataset, and the list of CWEs and counts of how many applications contained that CWE.
- We plan to calculate likelihood following the model we developed in 2017 to determine incidence rate instead of frequency to rate how likely a given app may contain at least one instance of a CWE.
But one of the ways that the OWASP Top Ten #1 is different than that is that this item is intended to include things other than rational databases, like ORMs, NoSQL data stores, and anything that’d be similarly executable. Even operating system commands that are injectable, like rm -rf . A big reason that this has been #1 for while (it was in 2013, 2010, etc) is the danger of this class of vulnerabilities is very high. In every update, the OWASP member-authors change the Top Ten list. The OWASP Top Ten list, as you might guess, is the ten most important things that OWASP think web application developers should be focused on to make sure that the web generally is secure.
Lesson 07 – OWASP Top 10 2017 – A3:2017-Sensitive Data Exposure
We plan to conduct the survey in May or June 2020, and will be utilizing Google forms in a similar manner as last time. The CWEs on the survey will come from current trending findings, CWEs that are outside the Top Ten in data, and other potential sources. XSS allows attackers to run scripts in a victim’s browser, which can hijack user sessions, de-identify websites OWASP Top 10 2017 Update Lessons or redirect the user to malicious websites. The basic idea that I feel the authors are going for here is that an application should have more auditible clarity for both users and its administrators about potential security issues it can make them aware of. Especially for non-technical people who web professionals often hand off deployments like WordPress to.
