Actually, Nessus 1.1.x has some plugins dedicated to the analysis of
CGIs. This is not as good as a humain brain with at least a two-digit
IQ, but that's better than just doing nothing.
(it will catch trivial things such as param=../../../../etc/passwd%00
and such, but not dir=/etc&file=passwd, even though the later seems
trivial to any human being).

But I agree with you - no automated tool can do a security _audit_.
There's more to a security audit than just flashing redlights and
showing /etc/passwd to the management. Policies have to be read and
correlated with the real life on the network. Services that do not match
the policy should be told to be disabled, even if they're not vulnerable
to anything.
A security audit is first a matter of checking that kind of thing rather
than licensing the list of vulnerabilities on a network. Vulnerabilities
appear and disappear every day. The policy never changes.
