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.
