Microsoft Windows WRITE_ANDX SMB packet denial of service
| win-writeandx-dos (45146) |  Low Risk |
Description:
The Microsoft Windows Server Message Block (SMB) Protocol is vulnerable to a denial of service, caused by improper validation of certain fields within an SMB packet. By sending specially-crafted WRITE_ANDX SMB packets to an interface allowing NULL sessions, a remote attacker could cause the system to stop responding and eventually restart.
