Description
A vulnerability has been identified in .NET Client Library for SIMATIC S7 Webserver API (All versions < V3.3.61). Affected applications do not properly validate filenames received from remote servers during ticket downloads.
This could allow an attacker who can manipulate the ticket response to write arbitrary files outside the intended download directory and, when overwriting is enabled, replace existing files accessible to the application.
