I didn’t see this reported anywhere, but since yesterday when there was an update to the metasploit module for the WMF vulnerability I think there’s been yet another update. I read yesterday that it had been updated and could evade all known IDS signatures. I downloaded the update to continue my Win98 testing. Then today found that there was another update. I haven’t compared the old/new versions but can’t help but wonder if this means more scrambling of antivirus writers for new signatures to keep up.

WMF exploit vs. Windows 98 again…
If you’ve visited here in the last few days, you’ll have noticed that I’ve been trying to test the WMF exploit against a Windows 98 Virtual machine since January 1st. I initially started out with a default install, which didn’t work, (for the exploit), then added irfanview (didn’t work), tried the exploit as a jpg, gif, htm, doc file extension, (didn’t work) and then this morning saw that I’m not the only one that’s been testing this….

WMF exploit testing on Windows 98
I had hoped to get in another test of Windows 98 with yet another WMF viewer (tried Kodak imaging, and irfanview). So far I haven’t seen a way that the WMF exploits can work on Windows 98 SE. I’m running out of time before I have to run to some computer service appointments and maybe will be able to pick up again this afternoon/evening. Larry Seltzer had a post this morning that earlier versions of Windows might not be as vulnerable because they had no default WMF viewer, but with a default WMF viewer they may be susceptible. I’m still looking for a WMF viewer that makes the exploit possible on Windows 98 SE.
