Описание
A tampering vulnerability exists when .NET Core improperly handles specially crafted files. An attacker who successfully exploited this vulnerability could write arbitrary files and directories to certain locations on a vulnerable system. However, an attacker would have limited control over the destination of the files and directories.
To exploit the vulnerability, an attacker must send a specially crafted file to a vulnerable system.
The security update fixes the vulnerability by ensuring .NET Core properly handles files.
A flaw was found in dotnet. Improper handling of specially crafted files can cause a path traversal vulnerability in .NET Core, allowing an attacker who can send a malicious file to a vulnerable system to write to arbitrary files and directories in certain locations.
