This flaw in the software design or implementation has been actively exploited in the wild, posing a severe threat to systems running these applications. The vulnerability can cause a denial of service against .NET applications and the Visual Studio Integrated Development Environment (IDE), disrupting their normal functioning. Reports have indicated that this vulnerability, along with multiple remote code execution vulnerabilities (CVE-2023-29328, CVE-2023-29330, CVE-2023-35385, CVE-2023-36895, CVE-2023-36910, and CVE-2023-36911), are at high risk of exploitation. This situation raises concerns about the potential for widespread system disruptions and unauthorized access to sensitive data. The Common Vulnerability Scoring System (CVSS) score for CVE-2023-38180 is 7.5, indicating its severity. Microsoft has acknowledged the existence of a Proof-of-Concept (PoC) exploit for the CVE-2023-38180 vulnerability. However, they noted that the PoC code or technique may not be functional in all situations and might require substantial modification by a skilled attacker. Microsoft has addressed this zero-day vulnerability and recommends immediate patching to mitigate the risk of exploitation and ensure the security of .NET applications and Visual Studio IDE.
