rwAuction Pro contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'searchtxt' variable upon submission to the 'search.asp' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Upgrade to version 4.0 (2006-04-19) or higher, as it has been reported to fix this vulnerability. Note that this flaw was fixed on or before April 16, 2006 without a change in version number. An upgrade is required as there are no known workarounds.
