CVE-2025-30399

Description

A remote code execution vulnerability in .NET 8.0 and 9.0. An attacker who can place malicious files in specific locations may trigger unintended code execution when the .NET runtime loads these files.

Statement

This vulnerability is Important because it allows remote code execution at the runtime level, targeting the fundamental assembly loading mechanism of .NET. Unlike moderate flaws that may require complex chaining or rely on user interaction, this issue can be exploited simply by placing malicious files in specific directories that .NET probes during execution.


.NET 6.0 for RHEL-8, RHEL-9 and RHIVOS has reached its End of Life as of November 12, 2024, and is no longer supported. No fixes will be provided for this stream.

Mitigation for this issue is either not available or the currently available options don’t meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
