RE: Microsoft Windows 2000 WebDAV Buffer Overflow Vulnerability

["Royans Tharakan" <RTharakan () ingenuity com>]

Did any one try this out ?

Someone said that OWA is not at risk so we are not patching it for webdav.
I tried using this code (wrote again perl) but it doesn't work against any
SP3 server.

How sure are you that this works ? I can send the perl version of this
code to anyone intrested in debugging this analysis tool.

rkt

You could give a look to the related Nessus plugin :
