DevBB contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate 'member' variables upon submission to the member.php script. This could allow a user to create a specially crafted URL that would execute arbitrary HTML and script code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by editing the source code to ensure that input is properly sanitised.
