The .NET ecosystem is vulnerable to various types of attacks, with remote code execution, cross-site scripting, and denial of service vulnerabilities accounting for 2/3 of known vulnerabilities. High severity vulnerabilities account for 70.7% of total vulnerabilities, while medium severity vulnerabilities make up the next largest share at 26.9%. The majority of vulnerabilities found in the .NET ecosystem are unique to it, with only three vulnerability types making up the majority of vulnerabilities. These vulnerability types include remote code execution, cross-site scripting, and denial of service attacks, which can have significant consequences for users. Fortunately, every vulnerability found by Snyk in a dependency scan has had a remediation available, suggesting that the .NET ecosystem receives strong support from Microsoft. Fixing vulnerabilities typically involves upgrading to a newer version of the affected package or dependency, with direct dependencies being easier to remediate than indirect ones. The .NET ecosystem faces challenges in terms of vulnerability reporting and disclosure, but tools like Snyk can help address this issue by providing a centralized place for vulnerability reporting and CVE number assignment.
