We have been unable to reproduce the problem with Roxen 1.3, but this is not fully analyzed yet, so it is suggested that a patch is applied as a precaution. Roxen SiteBuilder is ONLY affected by the directory listing vulnerability. Solution An update package labeled 'Fix for "%00" vulnerability' is available from the Roxen 2.0 update server. Use the administration interface to download and install this fix. Note that the server needs to be restarted when the fix is installed. A patch for Roxen 1.3.122 (the latest 1.3 release) is a available as ftp://ftp.roxen.com/pub/roxen/patches/roxen_1.3.122-http.pike.patch and should be applied to server/protocols/http.pike. The Roxen 2.0 upgrade package is also available as a patch if the update server can not be used for some reason: ftp://ftp.roxen.com/pub/roxen/patches/roxen_2.0.50-http.pike.patch Credits Problem originally reported by <zorgon@sdf.lonestar.org> Further comments on the problem by Elias Levy <aleph1@underground.org> -- Peter Bortas http://peter.bortas.org Roxen IS http://www.roxen.com
