c32web.exe in McMurtrey/Whitaker Cart32 before 6.4 allows remote attackers to read arbitrary files via the ImageName parameter in a GetImage action, by appending a NULL byte (%00) sequence followed by an image file extension, as demonstrated by a request for a “.txt%00.gif” file. NOTE: this might be a directory traversal vulnerability.
