  script_tag(name:"insight", value:"Multiple flaws are due to:

  - The web server does not filter user input correctly.

  - Email project accounts are stored in clear text.

  - The web server accepts commands via specific scripts that imitate trusted
    accounts.

  - The Web server settings, accounts, and projects may be modified through
    scripted commands.

  - WebAccess can be made to run remote code through the use of a browser
    plug-in.

  - The software reads or writes to a buffer using an index or pointer that
    references a memory location after the end of the buffer.

  - Normal and remote users have access to files and folders that only
    administrators should be allowed to access.

  - Unrestricted file upload vulnerability.

  - Insufficient sanitization of filenames containing directory traversal
    sequences.

  - Multiple stack-based buffer overflows.

  - Multiple heap-based buffer overflows.

  - Integer overflow in the Kernel service.");
