As Synk announces its support of unmanaged dependencies (mostly C/C++ libraries), we thought it would be beneficial to introduce our non-C community to some common, high-risk dangers that lurk in the C world (get it?). Think of this as a “beginners guide” to C and C++ vulnerabilities, how they look, what problems they may cause, and how to fix them.
Automation is a key component of DevSecOps because it increases efficiency. Automating work in your software development lifecycle helps you integrate multiple tools into your workflow. It also lets developers, maintainers, and security champions focus on coming up with creative solutions for tough problems, rather than spending time on tedious manual tasks.
GraphQL is an API query language developed by Facebook in 2015. Since then, its unique features and capabilities have made it a viable alternative to REST APIs. When it comes to security, GraphQL servers can house several types of misconfigurations that result in data compromise, access control issues, and other high risk vulnerabilities. While security issues with GraphQL are widely known, there’s little information on finding them outside of using dynamic analysis.
Last week, we announced the discovery of Spring4Shell — a remote code execution (RCE) vulnerability in older versions of the spring-beans package. In our blog post Spring4Shell: The zero-day RCE in the Spring Framework explained, we showed how an old Tomcat exploit for CVE-2010-1622 became relevant again. Due to the nature of the problem, we expected that additional payloads could be created beyond this known Tomcat exploit.
React provides an easy and intuitive way to build interactive user interfaces. It lets you build complex applications from small, isolated pieces of code called components. React Native is an extension of React that enables developers to combine techniques used for web technologies like JavaScript with React to build cross-platform mobile apps. This allows developers to write code once for multiple platforms, which speeds up development time.
Snyk can send a number of different types of email notifications. Notifications can be powerful when they enable you to learn about a new vulnerability, license issue, or fix an issue in your projects on the same day we find it. However, these alerts can be noisy if they aren’t configured according to the needs of your teams. That’s why we’ve made Snyk notifications flexible! Let’s take a look at how to make them work for you.
We’re happy to announce the general availability of C/C++ security scanning in Snyk Open Source, enabling development and security teams to find and fix known security vulnerabilities in their C/C++ open source library dependencies. 2:21
Directory traversal vulnerabilities (also known as path traversal vulnerabilities) allow bad actors to gain access to folders that they shouldn’t have access to. In this post, we are going to take a look how directory traversal vulnerabilities work on web servers written on C/C++, as well as how to prevent them.
“Never click unexpected links!” Ever hear someone yell this? Virtually every person in tech has a healthy suspicion of random links; it is for a good reason. Every now and then there are huge leaks from industry leaders as a result of a targeted campaign. One of the most reliable ways to “phish” someone, or exfiltrate their credentials, is to abuse an open redirect vulnerability in a safe-looking website and redirect the victims to a malicious one.
On March 30, 2022, a critical remote code execution (RCE) vulnerability was found in the Spring Framework. More specifically, it is part of the spring-beans package, a transitive dependency in both spring-webmvc and spring-webflux. This vulnerability is another example of why securing the software supply chain is important to open source.
