Which of the following ports are used by the NetBIOS protocol to share files and printers on a Windows network?
|
NetBIOS is a protocol used for File and Print Sharing under all current versions of Windows. While this in itself is not a problem, the way that the protocol is implemented can be. There are a number of vulnerabilities associated with leaving this port open. NetBios services: Show By default, when File and Print Sharing is enabled it binds to everything, including TCP/IP (The Internet Protocol), rather than just the local network, meaning your shared resources are available over the entire Internet for reading and deletion, unless configured properly. Any machine with NetBIOS enabled and not configured properly should be considered at risk. The best protection is to turn off File and Print Sharing, or block ports 135-139 completely. If you must enable it, use the following guidelines: 1. Use strong passwords, containing non-alphanumeric
characters. Keep in mind that you might still be leaking out information about your system that can be used against you (such as your computer and workgroup names) to the entire Internet, unless ports are filtered by a firewall. There is also a Critical Windows RPC vulnerability affecting ports 135,139 and 445, as detailed here: MS Technet Security Bulletin [MS03-026] The following trojans/backdoors also use these ports: W32.HLLW.Moega [Symantec-2003-080813-3234-99] W32.Reidana.A [Symantec-2005-032515-4042-99] (2005.03.27) - worm that spreads using the MS DCOM RPC vulnerability (MS Security Bulletin [MS03-026]) on port 139. The worm attempts to download and execute a remote file via FTP. Opens TCP port 4444. W32.Klez worm [Symantec-2002-031910-1028-99] - a class of worms that collects email addresses from an infected computer's Windows address book and propagates using its own SMTP server. As of April 26, 2002, there are nine variants of the Klez worm that all exploit the "Microsoft Internet Explorer Incorrect MIME header" vulnerability, which causes an email attachment to be automatically executed when an HTML email is previewed by a Microsoft Outlook or Outlook Express user. The worm can arrive as an email attachment with one of the following file extensions: asp, bak, c, cpp, doc, htm, html, jpg, mp3, mpg, mpeg, pas, rtf, wab, or xls. W32.Sircam.Worm [Symantec-2001-071720-1640-99] - a computer worm that propagates by e-mail from Microsoft Windows systems. It also spreads via open shares on a network. Sircam scans the network for computers with shared drives and copy itself to a machine with an open (non-password protected) drive or directory. Buffer overflow in a certain driver in Cisco Security Agent 4.5.1 before 4.5.1.672, 5.0 before 5.0.0.225, 5.1 before 5.1.0.106, and 5.2 before 5.2.0.238 on Windows allows remote attackers to execute arbitrary code via a crafted SMB packet in a TCP session on port (1) 139 or (2) 445. Server Message Block (SMB) also uses this port. It is used by Microsoft Windows file and print services, such as Windows Sharing in Mac OS X.
