MS03-034: Flaw in NetBIOS Could Lead to Information Disclosure (824105) (uncredentialed check)

medium Nessus Plugin ID 11830


The remote service is affected by an information disclosure vulnerability.


The remote host is running a version of the NetBT name service that suffers from a memory disclosure problem.

An attacker may send a special packet to the remote NetBT name service, and the reply will contain random arbitrary data from the remote host memory. This arbitrary data may be a fragment from the web page the remote user is viewing, or something more serious like a password.

An attacker may use this flaw to continuously 'poll' the content of the memory of the remote host and might be able to obtain sensitive information.


Microsoft has released patches for Windows NT, 2000, XP, and 2003.
