  ...if you are looking for commercial solutions, OunceLabs code scanner
supports ASP Classic..

  .. the problem is that due to the architecture of the ASP Classic language
(as in no real support for classes and wide use of includes) these scanners
(Ounce's included) tend to find stupid amounts of real vulnerable paths ( as
in 15k+) which are technically correct, but tend to be most the same pattern
(same call flows using different files)

So, to deal with these findings and quickly identify the unique insecure
patters (which are usually only in the 10x number) you should use the
modules from open source toolkit that I have been developing for the last
year which is called O2 and you can get from http://www.o2-ounceopen.com (for
example my latest filtering module 'Ozamst Query' is able to load 300mb of
assessments in minutes and run dynamic user created Lambda queries in
seconds :)  )

Note, if you are aware of an open source ASP Classic scanner, please let me
know and I will integrate it with O2 (to see how other scanning engines can
be used and controled by O2, checkout the MsCatNet module which uses the
Microsolt Cat.Net security scanner to scan the code an then converts it's
results into Ounce/O2 saved findings assessment format (Ozasmt)
