Lesson 11 OWASP Top 10 2017 A7:2017-Cross-Site Scripting XSS Conviso Platform Docs

If at all possible, please provide core CWEs in the data, not CWE categories. This will help with the analysis, any normalization/aggregation done as a part of this analysis will be well documented. 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.

  • It’s been nearly 20 years since the Open Web Application Security Project (OWASP) was launched.
  • 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.
  • 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”.
  • Additionally, the scoring ranges and formulas were updated between CVSSv2 and CVSSv3.

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. Like #1, the OWASP #2 for 2017 is largely similar to the same item from 2013. Authentication is the way that an application knows who a user is.

We grouped all the CVEs with CVSS scores by CWE and weighted both exploit and impact scored by the percentage of the population that had CVSSv3 + the remaining population of CVSSv2 scores to get an overall average. We mapped these averages to the CWEs in the dataset as Exploit and Impact scoring for the other half of the risk equation. The latest OWASP Top 10 represents the first update to the vulnerability ranking since 2013. Especially for non-technical people who web professionals often hand off deployments like WordPress to. 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.

  • By default, many older XML processors allow specification of an external entity, a URI that is dereferenced and evaluated during XML processing.
  • The updated list also marks the first time “Insecure Design” has appeared on the list, notable simply because it relates to a missing (or flawed) step before development even begins.
  • 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.
  • On the other hand, the tools to detect them are getting better and better.
  • Several topics will be addressed in future blog posts e.g., which vulnerability scan types are available and which points can be tested automatically.

We spent a few months grouping and regrouping CWEs by categories and finally stopped. We have ten categories with an average of almost 20 CWEs per category. The smallest category has one CWE, and the largest category has 40 CWEs. We’ve received positive feedback related to grouping like this as it can make it easier for training and awareness programs to focus on CWEs that impact a targeted language or framework.

Data Structure

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. 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. 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.

  • To avoid these security problems, software development teams must be aware of software security.
  • We will carefully document all normalization actions taken so it is clear what has been done.
  • Attackers can steal or modify this poorly protected data to carry out credit card fraud, identity theft or other crimes.
  • … 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.

The heart of this is that you must make sure that your deployments are secure-by-default, rather than spinning them up in a way that requires hardening after-the-fact. Correctly (to my mind), the author’s at OWASP recognize that after-the-deploy hardening gets skipped, so I love their recommendation to just never do it. It also fits well with the increasing Docker- or container-ization of web stacks.

But with the increasing amount of services also the complexity of authorization and ACL handling increases.SSRF is new in the OWASP Top 10, and it is currently only a small cluster of a single CWE. But https://remotemode.net/become-a-net-razor-developer/owasp-top-10-2017-update/ with the increasing usage of microservice architectures, this attack will become more common, and we need to focus on it. XXE is an attack against an application that processes XML input from a client.
