What is CVE-2019-6617?

On certain versions of BIG-IP by F5 Networks, users assigned the Resource Administrator role can exploit a vulnerability that allows them to overwrite sensitive low-level files, such as '/etc/passwd', using SFTP. This occurs without requiring Advanced Shell access, which contravenes the defined restrictions for the Resource Administrator role. This flaw exposes critical system files to unauthorized modifications, potentially leading to unauthorized access and privilege escalation.
