This is contrary to our definition for the Resource Administrator (RA) role restrictions. (CVE-2019-6617) Impact An attacker with the Resource Administrator role may be able to manipulate user privileges. Security Advisory Status F5 Product Development has assigned ID 745165 (BIG-IP) to this vulnerability. Additionally, BIG-IP iHealth may list Heuristic H38941195 on the Diagnostics > Identified > Medium page. To determine if your product and version have been evaluated for this vulnerability, refer to the Applies to (see versions) box. To determine if your release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases or hotfixes that address the vulnerability, refer to the following table.

However, F5 identifies the vulnerability status as Not vulnerable because the attacker cannot exploit the code in default, standard, or recommended configurations. Security Advisory Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Fixes introduced in column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. Mitigation None Acknowledgements F5 would like to acknowledge Rich Mirch for bringing this issue to our attention and following the highest standards of responsible disclosure.
