What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Syncplify Server! before 8.8.0 contains an access control bypass vulnerability that allows authenticated SFTP users to evade per-path permission overrides by exploiting case-insensitive filesystem path resolution and 8.3 short names. Attackers can address a protected directory using alternate capitalization or its 8.3 short name to perform file uploads and downloads that the configured override is intended to deny, resulting in unauthorized file access.
