GoAhead WebServer before 2.1.6 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an invalid URL, related to the websSafeUrl function.
Directory traversal vulnerability in GoAhead Web Server 2.1 allows remote attackers to read arbitrary files via a URL with an encoded / (%5C) in a .. (dot dot) sequence. NOTE: it is highly likely that this candidate will be REJECTED because it has been reported to be a duplicate of CVE-2001-0228.
Cross-site scripting vulnerability in GoAhead Web Server 2.1 allows remote attackers to execute script as other web users via script in a URL that generates a "404 not found" message, which does not quote the script.
GoAhead Web Server 2.1.7 and earlier allows remote attackers to obtain the source code of ASP files via a URL terminated with a /, \, %2f (encoded /), %20 (encoded space), or %00 (encoded null) character, which returns the ASP source code unparsed.
