What is CVE-2018-25421?

The Open STA Manager 2.3 is susceptible to a path traversal vulnerability that can be exploited by authenticated users. By crafting specific GET requests to the 'modules/backup/actions.php' endpoint, attackers can manipulate the file parameter to navigate through directories using '../' sequences. This enables the unauthorized download of sensitive files from the server, potentially leading to data leakage or selection of critical configuration files.
