Buffer overflow in httpd32.exe in Deerfield VisNetic WebSite before 3.5.15 allows remote attackers to cause a denial of service (crash) via a long HTTP OPTIONS request.

Cross-site scripting (XSS) vulnerability in VisNetic Website before 3.5.15 allows remote attackers to inject arbitrary web script or HTML via the HTTP referer header (HTTP_REFERER) to a non-existent page, which is injected into the resulting 404 error page.

VisNetic WebSite 3.5 allows remote attackers to obtain the full pathname of the server via a request containing a folder that does not exist, which leaks the pathname in an error message, as demonstrated using _vti_bin/fpcount.exe.
