| Solution | Users are advised to apply the vendor patch for MS09-001 . |
| Vendor description | This security update resolves several privately reported vulnerabilities in Microsoft Server Message Block (SMB) Protocol. The vulnerabilities could allow remote code execution on affected systems. An attacker who successfully exploited these vulnerabilities could install programs; view, change, or delete data; or create new accounts with full user rights. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed. |
| SophosLabs comments | Successful exploitation of this vulnerability causes the denial of service on the targeted server. In addition to that the attacker might be able to execute code remotely and take control over the targeted system. Sophos Endpoint Security and Control Client Firewall may be used as a workaround for protecting against attacks attempting to exploit this vulnerability by configuring it to block incoming traffic on TCP ports 139 and 445. |
| SophosLabs testing result | N/A |
| Currently known exploits | At the time of writing SophosLabs has seen no samples of malware attempting to exploit this vulnerability. Should this situation change samples will be analysed and we will take action as necessary. |
