Name of the Vulnerable Software and Affected Versions Evil-WinRM versions prior to commit 6ecd570
Description A path traversal issue exists in the download dir() function. This occurs when the software fails to sanitize filenames returned from the Get-ChildItem command output before passing them to File.join(). A compromised or rogue remote Windows server can return filenames containing traversal sequences, enabling the server to write files outside the intended download directory on the client machine. This can be used to overwrite sensitive files, such as SSH authorized keys or shell configuration files, potentially leading to privilege escalation or persistent access on the client system.
Recommendations Update to the version containing commit 6ecd570. As a temporary workaround, restrict the use of the download dir() function when connecting to untrusted remote servers.
