This can be explained by the fact that it has been around the longest, has the highest volume of written code, and is the base of all the infrastructures that we use. The use of automated tools and the trend of bug bounty programs have changed the game and led to a significant rise in reported vulnerabilities in While we saw a spike in the number of reported security vulnerabilities over the past two years, the number of high severity vulnerabilities has decreased in most languages.

Before we delve further into the research, there are two considerations that we should take into account in assessing these projects. While on the face of the findings some might mistakenly assume that C is inherently more vulnerable, this is not the case. For starters, more code has been written than any other language, providing more opportunities for vulnerabilities to be discovered. The fact is that C has been in use for much longer than most other languages, and is behind the core of most of the products and platforms we use.

As such, it is bound to have more known vulnerabilities than the rest. When we crunch the numbers and review the amount of reported open source vulnerabilities per programming language over time, what stands out is that there is no consistent trend for all languages apart from the fact that all languages saw a significant rise in the number of reported vulnerabilities in While each language has had its own highs and lows, vulnerability-wise, over the past ten years, there are a few reasons behind the rise in vulnerabilities.

Heightened awareness of security vulnerabilities in open source components, combined with the rise in the popularity of open source, have brought more focus to this open source security research. This attention has resulted in more issues being discovered.

In addition, automated tools and the large investment in bug bounty programs have further contributed to the substantial increase in the number of reported open source issues. When we went deeper into the vulnerabilities data and focused on vulnerabilities with a high severity above 7 according to CVSS v2 , we found that although there was a spike in the number of reported vulnerabilities in , the percentage of critical vulnerabilities is declining in most of the languages we researched, excluding JavaScript and PHP.

The decrease in critical vulnerabilities might be explained by the concerted effort from security researchers to use automated tools to discover vulnerabilities in open source components. These tools most often are usually less capable of uncovering more complex and critical issues. While many of these tools are doing a good job of uncovering new vulnerabilities, many of the new security flaws discovered are not critical, and so we see a rise in the number of mostly medium vulnerabilities.

We next chose to examine the types of vulnerabilities that were appearing in each language, to study another aspect of the threats to their security. To better understand their weak and strong points, we analyzed the types of CWEs that were found in each language over time.

When we looked at the rise and fall of different CWEs in different languages over the years, we found that while some CWEs ebb and flow, on the most part, they refuse to go away:. C is the language with the highest number of reported vulnerabilities of the bunch, by far. C projects combined boast a huge open source development community — possibly the largest open source community out there.

On the other hand, it is the only language that has a high number of memory corruption issues, which are considered a critical type of vulnerability. This is understandable since most of the CWEs common in other languages are related to web and web services issues, which are not relevant in C. This allows us to learn exactly which open source libraries experienced growth in reported known vulnerabilities, following the rise in vulnerabilities over the years.

We can see that Linux vulnerabilities have nearly always accounted for a high percentage of vulnerabilities in C. Java vulnerabilities have been consistently rising since While for most languages in this report the numbers went down this year, Java is the only language that saw a rise in open source vulnerabilities this past year. Surprisingly perhaps, Java vulnerabilities nearly doubled in as compared to Should researchers start looking for Deserialization issues in those languages too, or is serialization inherently more secure in the other languages?

JavaScript, arguably the most popular language, is one of the only languages that saw a continuous rise in the number of vulnerabilities in the past ten years. In the number of reported vulnerabilities was 16 times higher than and continued to rise in The rise in the number of known vulnerabilities may be attributed to its rising popularity, along with the fact that JS has become popular as a language for backend in recent years. Many of them come from few researchers and are vulnerabilities in unpopular or even dead packages.

Meaning — these are unnatural CVEs. When we look at the years these vulnerabilities spiked, we see that nearly all of the Cryptographic Issues CWE were found in , and the vast majority of the Path Traversal issues WEE were found in If we really want to understand how vulnerable a programming language or project is and what their weak points are, quantity is not enough.

This information is sometimes under-the-radar, with varying levels of credibility. PHPs popularity has been in decline for the past few years. But if you steal crypto currency? The good news: law enforcement is getting better at tracing these transactions and following the money, the bad news: the blockchain industry is not very mature when it comes to identifying vulnerabilities and weaknesses. Attacks rely on a vulnerability being present so that they can exploit it.

These vulnerabilities are implemented in software web services, smart contracts, the underlying blockchain system, etc. And there is no comprehensive public list of weaknesses. Also like most things in life given the choice between using a public database or building your own data set most security scanning tools use the CWE database as their baselines for security flaws that they try to detect and offer guidance on remediating.

This means that Blockchain and smart contract security scanning tools will probably detect common and known issues like integer overflows and memory leaks. But they may not detect Blockchain and smart contract specific vulnerabilities as well since there is no good, comprehensive, public database to use as a source. The Cloud Security Alliance is of course working on this issue, we currently have a rough list of almost weaknesses that apply to Blockchain and smart contracts, and about half of which are not in any other public database of weaknesses.

The goal is to make this list of weaknesses more detailed and comprehensive, and encourage other public databases such as CWE or SWC Registry to include then so that ultimately automated tools will include support for them, making it easier for developers and end users to find, understand and fix vulnerabilities because attackers find and exploit them.

Certain cryptographic operations such as using CBC or ECB incorrectly allow blocks to be re-ordered and the results will still decrypt properly. By creating a large number of fake peers in a network peer to peer or otherwise an attacker can cause real nodes to slow down or become non responsive as they attempt to connect to the newly announced peers.

By creating a large number of slow peers real systems that respond very slowly to network requests in a network an attacker can cause real nodes to slow down or become non responsive as they attempt to connect to the newly announced peers. Unlike fake peers that do not exist these slowloris peers are real but communicate slowly enough to hold sockets and resources open for minutes or hours.
