Network denial of service in Microsoft .NET 8.0, 9.0, and 10.0 (and the corresponding Visual Studio 2022/2026 tooling) allows an unauthorized remote attacker to exhaust system resources and render affected applications unavailable. The flaw stems from allocation of resources without limits or throttling, meaning a single crafted network interaction can trigger disproportionate resource consumption. Reported by Microsoft with a vendor patch available; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in Microsoft .NET (including .NET 8.0/9.0/10.0 and .NET Framework 3.5 through 4.8.1) lets a remote unauthenticated attacker exhaust server resources by sending crafted network traffic that triggers unbounded resource allocation. Rated CVSS 7.5 with availability-only impact, it affects default configurations of network-facing .NET applications; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Security feature bypass in Microsoft .NET (versions 8.0, 9.0, and 10.0) lets a remote, unauthenticated attacker circumvent an authorization control over the network due to incorrect authorization logic (CWE-863). Rated CVSS 8.2, the flaw carries a high integrity impact and requires no privileges or user interaction, though there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Microsoft has released a patch, and the affected surface also includes Visual Studio 2022 (17.12, 17.14) and Visual Studio 2026 (18.7) tooling that bundle the runtime.
Denial of service in Microsoft .NET (versions 8.0, 9.0, and 10.0) and .NET Framework (3.5 through 4.8.1) allows a remote, unauthenticated attacker to crash affected applications by triggering a stack-based buffer overflow (CWE-121) over the network. The flaw impacts availability only - there is no confidentiality or integrity loss and no code execution per the CVSS vector (A:H, C:N, I:N). Microsoft has published an advisory with fixes; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
Network-based denial of service in Microsoft .NET 8.0, 9.0, and 10.0 allows an unauthenticated remote attacker to exhaust server resources and render applications unresponsive by exploiting uncontrolled resource allocation (CWE-770) in the runtime. The flaw carries CVSS 7.5 (availability-only impact) and affects the shared .NET runtime that underpins ASP.NET Core web services, so any internet-facing .NET workload is exposed. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; Microsoft has released a fix.
Remote denial of service in Microsoft .NET (versions 8.0, 9.0, and 10.0) allows an unauthenticated network attacker to crash or hang the runtime by sending crafted input that fails proper type validation (CWE-1287). The flaw carries a CVSS 7.5 rating driven entirely by availability impact (A:H) with no confidentiality or integrity loss, and no public exploit has been identified at time of analysis. Microsoft has released a patch; there is no indication of active exploitation.
Privilege elevation in ASP.NET Core (bundled with .NET 8.0, 9.0, and 10.0) lets an already-authenticated, low-privileged network attacker bypass authentication controls by tampering with data the framework wrongly assumes to be immutable (CWE-302). Microsoft reported and patched the flaw; there is no public exploit identified at time of analysis and it is not on CISA KEV. At CVSS 8.8 with PR:L, an authorized user can escalate to higher privileges over the network.
Denial of service in Microsoft .NET (versions 8.0, 9.0, and 10.0) and the legacy .NET Framework (3.5 through 4.8.1) allows a remote unauthenticated attacker to exhaust server resources over the network, causing availability loss. The flaw stems from missing limits or throttling on resource allocation (CWE-770), and Microsoft has released a patch via MSRC. There is no public exploit identified at time of analysis, and EPSS/KEV data were not supplied, so this appears to be a proactively patched issue rather than one under active exploitation.
Privilege elevation in ASP.NET Core (bundled with .NET 8.0, 9.0, and 10.0) lets an already-authenticated, low-privileged network attacker gain higher privileges by abusing a flawed authentication algorithm implementation (CWE-303). Microsoft reported the flaw and has released a patch; there is no public exploit identified at time of analysis and it is not on the CISA KEV. The 8.8 CVSS reflects high confidentiality, integrity, and availability impact reachable over the network with only low prior privileges.
Denial of service in Microsoft .NET (versions 8.0, 9.0, and 10.0) allows a remote, unauthenticated attacker to crash or hang affected applications by triggering a type-confusion condition (CWE-843) over the network. The flaw was reported by Microsoft and a vendor patch is available via MSRC; there is no public exploit identified at time of analysis. The CVSS vector limits impact strictly to availability (A:H, C:N/I:N), meaning it is a service-disruption bug rather than a code-execution or data-exposure issue despite tag noise suggesting otherwise.
Denial of service in ASP.NET Core (the web framework shipped with .NET 8.0, 9.0, and 10.0) lets a remote, unauthenticated attacker exhaust server resources by triggering unbounded allocations over the network. Because affected requests are not throttled or capped, a single crafted request stream can degrade availability of the hosting process without any authentication or user interaction. Reported by Microsoft with a vendor patch available; no public exploit identified at time of analysis and no CISA KEV listing.
Remote denial of service in ASP.NET Core (.NET 8.0, 9.0, and 10.0) allows an unauthenticated attacker to send crafted network requests that trigger a loop with an unreachable exit condition (CWE-835), pinning CPU and rendering the application unresponsive. Publicly available exploit code exists, though there is no public exploit identified as being used in active attacks; EPSS is very low (0.04%, 12th percentile), consistent with the CISA SSVC 'Exploitation: none' assessment. Microsoft has released fixed runtime packages, and the flaw is availability-only with no confidentiality or integrity impact.
Local privilege elevation in Microsoft .NET (Windows Desktop/WPF runtime) for versions 8.0, 9.0, and 10.0 allows an attacker to run code at a higher privilege level after a targeted user opens crafted input. The root cause combines improper input validation (CWE-20) with a heap-based buffer overflow (CWE-122), yielding total technical impact per CISA SSVC. Publicly available exploit code exists, but the vulnerability is not in CISA KEV and EPSS is low (0.11%, 30th percentile), indicating no observed widespread exploitation to date.
Local privilege escalation in Microsoft .NET Framework (versions 3.5 through 10.0) and Visual Studio 2017 occurs through heap-based buffer overflow exploitation requiring user interaction with a malicious file. Attackers without initial privileges can achieve high-level code execution and data access by convincing a user to open a specially crafted document or application. Microsoft has released patches across all affected .NET versions per MSRC advisory, indicating this is a vendor-confirmed issue requiring immediate remediation for systems where users process untrusted .NET content.
Denial of service via stack buffer overflow in .NET (versions 8.0, 9.0, 10.0) and Visual Studio 2022 (versions 17.12, 17.14) allows unauthenticated remote attackers to crash affected applications over the network. The vulnerability has a CVSS score of 7.5 (High) with low attack complexity and no privileges required. Vendor-released patches are available from Microsoft (MSRC). No public exploit identified at time of analysis, and the issue is not confirmed actively exploited.
Denial-of-service condition in Microsoft .NET Framework 8.0, 9.0, and 10.0 allows unauthenticated remote attackers to exhaust system resources through network-based uncontrolled resource consumption. Affects .NET 8.0 versions prior to 8.0.26, .NET 9.0 versions prior to 9.0.15, and .NET 10.0 versions prior to 10.0.6. Microsoft has released patches addressing CWE-400 resource exhaustion. No evidence of active exploitation (not listed in CISA KEV) at time of analysis, though the network-accessible, unauthenticated attack vector and low complexity (CVSS AV:N/AC:L/PR:N) present significant availability risk for internet-facing .NET applications.
Infinite loop denial-of-service vulnerability in Microsoft .NET Framework (3.5 through 4.8.1), .NET 8.0, 9.0, and 10.0 allows unauthenticated remote attackers to exhaust server resources via specially crafted network requests. The vulnerability (CWE-835) stems from unreachable loop exit conditions in core .NET processing logic, enabling complete service disruption with low attack complexity. Vendor-released patches are available across all affected product lines. No public exploit identified at
Information disclosure in Microsoft .NET 8.0, 9.0, 10.0, and Visual Studio 2022 allows unauthenticated remote attackers to access sensitive data through improper neutralization of special elements. This spoofing vulnerability (CWE-138) enables attackers to bypass authentication mechanisms and extract high-confidentiality information over the network with low attack complexity. No active exploitation confirmed (not in CISA KEV), but the network-accessible, no-authentication-required attack profile presents immediate risk for internet-facing .NET applications. Vendor patches available for all affected versions.
Output spoofing via improper encoding in Microsoft .NET 8.0, 9.0, and 10.0 allows a low-privileged network attacker to manipulate encoded output, enabling content or identity spoofing with high integrity impact. Affected products span three active .NET generations plus Visual Studio 2022 (17.12, 17.14) and Visual Studio 2026 (18.7), creating a broad enterprise attack surface. A publicly available proof-of-concept exploit exists on GitHub; however, CISA SSVC reports exploitation status as none and EPSS sits at 0.41% (34th percentile), suggesting opportunistic rather than widespread active threat activity at time of analysis.
Local tampering via symbolic-link following in Microsoft .NET (versions 8.0, 9.0, and 10.0) and the bundled toolchain in Visual Studio 2022 (17.12, 17.14) and Visual Studio 2026 (18.7) allows an authorized local attacker to redirect a privileged file operation to an unintended target, corrupting or replacing files outside their normal permissions. Microsoft (the reporter) has released a fix; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV. The high CVSS 3.1 base score of 7.0 is tempered by high attack complexity and the requirement for existing low-level local access.
Absolute path traversal in Microsoft .NET Core (Windows runtime, versions 8.0 through 10.0) enables a network-accessible attacker to write arbitrary files and directories to restricted locations on a vulnerable system by sending a specially crafted file. Exploitation is constrained by limited attacker control over the write destination, and SSVC assessment rates exploitation as 'none' with non-automatable impact, consistent with the low EPSS of 0.08%. A publicly available proof-of-concept exists on GitHub Gist, but no confirmed active exploitation appears in CISA KEV; patched runtime versions are available for all affected .NET branches.
