Similar to Injection, “broken authentication” really contains a whole host of vulnerabilities inside of it. Both weak password storage and allowing for things like cookie stuffing via stolen OWASP Top 10 2017 Update Lessons session IDs are examples of this vulnerability. There’s some substantial debate among people who think and talk about web security about the quality and substance of the OWASP changes.
Today, OWASP’s Top 10 is the de facto generic vulnerability standard for many in the industry, with valuable insights into where we are as an industry and where we continue to struggle. • A10 – Unvalidated Redirects and Forwards, while found in approximately 8% of applications, it was edged out overall by XXE. • 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. If you read through the above, you may be wondering what changed between this revision and the previous. In general sanitization is a protection from this class of attacks, but a better one is a safe API.
No software. No set up. Unlimited access.
The latest OWASP Top 10 represents the first update to the vulnerability ranking since 2013. If you have powerful administration accounts, and it’s relatively easy for an attacker to get access to those accounts, you’ve got a serious authentication issue. The rapid expansion of the attack surface is also accompanied, the attacker can always find a new attack surface. Within this context, after four years we once again usher in OWASP Top 10 update. 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.
- Authentication is the way that an application knows who a user is.
- If, like me, you write a lot of PHP, you’ll need to keep this one in mind for a long time.
- And so I don’t see this changing drastically in position until either tooling gets a lot better, or humans become much more concerned about this as a general security practice.
- The basic logic and protection here is not complicated, but the position of this list has not changed because people are lazy and the tools are generally not super good.
“Injection” as a class of security flaw often gets shortened in my head to simply “SQL injection.” For the initiated, SQL is the language that relational databases like MySQL, Postgres, Microsoft SQL, etc speak. SQL Injection vulnerabilities come about when an unvalidated user-accessible field can have extra SQL queries like DROP TABLE users; put into the middle and executed by a database. XSS allows attackers to run scripts in a victim’s browser, which can hijack user sessions, de-identify websites or redirect the user to malicious websites. That means 18 years is still not long enough for us, as an industry, to remedy these flaws.
Quick Rundown of the OWASP Top Ten
AppSec Starter is a basic application security awareness training applied to onboarding new developers. It is not the purpose of this training to discuss advanced and practical topics. Conviso has customized training and practical training platforms.
The acronym stands for “Open Web Application Security Project.” It is generally regarded as one of the best sources of information about keeping the internet (and applications built upon it) secure. It’s largely a community-driven endeavor which aims to make the internet more secure by helping people to find trustworthy information about what they can do to keep their web apps and tools from getting hacked. 2017 and 2013 version mapping relationship see the following figure. Compared to the 2013 version, some of the risk factors also have some changes. To collect the most comprehensive dataset related to identified application vulnerabilities to-date to enable analysis for the Top 10 and other future research as well. This data should come from a variety of sources; security vendors and consultancies, bug bounties, along with company/organizational contributions.

But what it is is a great baseline for discussion and processing what people want and need to know. It’s a place for a conversation about security to start, and good thing to keep an eye on for anyone who writes or maintains any part of a web application. It’s certainly not the case that understanding the Open Web Application Security Project’s Top 10 list is sufficient for you to be an expert on web application security. It, for example, says nothing about how you should keep your personal passwords, or even much about how best to store passwords.
PHP applications have had this type of vulnerability for ages, because the language’s native support for a specific type of serialization. One which assumes an unrealistic amount of security in storage, and so lets the language’s unserialize call do dangerous things. By default, many older XML processors allow specification of an external entity, a URI that is dereferenced and evaluated during XML processing. … These flaws can be used to extract data, execute a remote request from the server, scan internal systems, perform a denial-of-service attack, as well as execute other attacks. 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.
A9:2017 – Using Components with Known Vulnerabilities
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.
