Rust Behind Glovebox

[DCTDC]

Hi there,

I took out the glovebox earlier to replace a fuse, only to be greeted by powdery rust along the metal beam behind it as per this photo I stole from google images:

Given other cars show rust there, should I be concerned? Is it a common problem I can fix?

Knee-jerk I figured I'd hammerite it over the weekend, but there's no pitting, just dusty rusty powder.
