Yes, though you don't need the []:

    foo=".*"

is a valid sed regexp.

You're experiencing a sed/sh quoting interaction problem.
Use single quotes around the sed expression and you'll be ok.
This worked for me:

    fleche. cat /tmp/X
    foo="bar"
    fleche. sed 's/foo=".*"/foo="new_value"/' < /tmp/X
    foo="new_value"
