This is very dangerous. You could corrupt storage this way very easily
if index is greater than sizeof(profile).

Try it with this modification:

memset(profile, 0x0, sizeof(profile));
strncpy(profile, buffer, index < sizeof(profile)-1 ? index :
sizeof(profile)-1);

Not able to do this because index is calculated thru strstr.

I changed the code to be like below:
memset(profile, 0x0, sizeof(profile));
strncpy(profile, buffer, index);
profile[sizeof(profile) - 1] = 0;
