Name of the Vulnerable Software and Affected Versions: zwserver versions (affected versions not specified)

Description: The issue concerns a directory traversal problem, allowing an attacker to access the filesystem by manipulating the URL with "../". This can lead to the disclosure of private files on the system. A malicious actor can exploit this to access files outside the intended directory root. For example, an attacker can send a GET request to "/../../../../../../../../../../etc/passwd" to access sensitive files.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to sensitive files and directories until a patch is available. Avoid using the zwserver package for production environments; instead, use it only for local development or consider an alternative package that provides the necessary functionality without this issue.
