Blocking VML with ISA 2004 & ISA 2006

  • 發行項

http://www.microsoft.com/technet/security/advisory/925568.mspx discusses a vulnerability in the VML parsing dll which can result in an unpleasant experience.

http://www.microsoft.com/technet/isa/2006/how-to-block-vml.mspx discusses a methodology by which you can use ISA 2004 or ISA 2006 to block HTTP-based attacks targeted against this vulnerability.

Finally, http://isatools.org/block_vml.vbs automates the process of creating the proper HTTP Filter settings for you.

Tim's report was accurate (see my comments). I've updated the script to version 1.2 and reposted it. Many thanx to Tim for his discovery.

Thank you,

Jim Harrison (ISA Sustained Engineering)

    UPDATE

    Tim's report uncovered an odditiy in VBScript processing of the 'and' test.  changing the script to a 'nested if' fixed the problem.

    ..I like JScript soooo much better...

    Just installed in a test environment and had one problme on ISA 2006. It broke rpc/https publishing. I had to uncheck the filters to make it work.
