GEN:SID | 1:3137 |
Message | NETBIOS SMB-DS Trans2 QUERY_FILE_INFO attempt |
Summary | This event is generated when an attempt is made to exploit a known vulnerability in Microsoft systems using Server Message Block (SMB).
|
Impact | Serious. Execution of arbitrary code leading to unauthorized administrative access to the target host. Denial of Service (DoS) is also possible.
|
Detailed Information | SMB is a client - server protocol used in sharing resources such as files, printers, ports, named pipes and other things, between machines on a network.
A vulnerability in the Microsoft implementation of SMB exists due to a programming error which may present an attacker with the opportunity to exploit the service and run code of their choosing on an affected system. The attacker may then cause a DoS condition in the service or possibly gain unauthorized access to the target host.
A malicious attacker can exploit the vulnerability by sending a malicious response from a server in response to a client request using SMB.
|
Affected Systems | Microsoft Windows 2003 Microsoft Windows 2000 Microsoft Windows XP
|
Attack Scenarios | An attacker can supply extra data in the message from the server containing code of their choosing to be run on the client.
|
Ease of Attack | Simple.
|
Corrective Action | Apply the appropriate vendor supplied patches.
Turn off windows file and print services.
Use Samba as an alternative.
