On BIG-IP 14.0.0-14.1.0.1, 13.0.0-13.1.1.4, 12.1.0-12.1.4, 11.6.1-11.6.3.4, and 11.5.2-11.5.8, a user with the Resource Administrator role is able to overwrite sensitive low-level files (such as /etc/passwd) using SFTP to modify user permissions, without Advanced Shell access. This is contrary to our definition for the Resource Administrator (RA) role restrictions.

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
