Technical details

A directory traversal vulnerability (CWE-22) exists in the Smart Slider 3 plugin for WordPress due to insufficient input validation in the 'replaceHTMLImage' function. The flaw is located within the administrative controller and backup export components of the plugin. An authenticated attacker with 'Administrator' or higher privileges can exploit this by submitting crafted requests that use 'dot-dot-slash' (../) sequences to navigate outside the intended directory. This allows for the unauthorized reading of arbitrary files on the server. The vulnerability is addressed in versions following 3.5.1.36.
