CVE-2017-16211

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

Description: The issue allows an attacker to access the filesystem by exploiting a directory traversal vulnerability. This can be achieved by placing "../" in the URL, giving access to files outside of the intended directory root, potentially leading to the disclosure of private files on the vulnerable system. For example, a malicious actor 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 the lessindex package, and if the functionality is needed for production, use a different package instead.
