There is (or was) a pen like thing that was like a paint pen that would lay down a metallic substance that would allow someone to fix a cut trace or other injury to a board trace. I've seen some of its handy work on refurbed or reworked boards occasionally. Something on the order of
this handy thing. All you have to do is clear away the surface to get enough to scribble it on. I had also seen something for replacing pads that involved using stick on pads that had bare metal edges that would solder to the traces at either end. Trouble is, I can't find that stuff at the moment.
Here is an idea from a very tangential site that I've c&p'ed to save you the trouble:
Broken pcb traces and pads, bridging pcb holes that are too small for the component leg going through, so solder cracks, etc
Eventually found a hobby shop with what I was after 2 copper and 2 brass 80 mesh 5 x 6 inch sheets, bit finer than I was after but finer is better than coarser.
Amaco of Indianapolis, Wireform Metal Mesh and Wiremesh woven Fabric. Presumably bigger sheets of it are used by the mind control nutters. A 2 hole paper punch makes neat 5mm pads and a needle to make a pilot hole.
Although this idea *could* actually work, it would involve having the mesh solder to the two ends of the existing traces AND the pad from the cable. If the board is single sided/single layered, you might get away with drilling a small hole that you could fill with solder making it a solder sink that would give you the opportunity to fake a pad, but I would strongly doubt that that board fits either of those criteria.
Oh, another idea is to form a 'solder bridge' between the two traces and then solder to that. Be careful that you don't extend the bridge over to other traces, use solder sparingly...

And actually from the picture, it looks like part of the cable is stuck, and the pad is OK. GRanted, the picture is a little fuzzy...
