| Vulnerability name/brief description | MS10-054 - Vulnerabilities in SMB Server Could Allow Remote Code Execution (982214) |
| CVE/CAN name | CVE-2010-2550 CVE-2010-2551 CVE-2010-2552 |
| Vendor threat level | Critical |
| SophosLabs threat level | Medium |
| Solution | |
| Vendor description | This security update resolves several privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow remote code execution if an attacker created a specially crafted SMB packet and sent the packet to an affected system. Firewall best practices and standard default firewall configurations can help protect networks from attacks originating outside the enterprise perimeter that would attempt to exploit these vulnerabilities. |
| SophosLabs comments | The patch encompasses how Windows validates SMB packets. In the worst case, successfully exploiting these vulnerabilities would leave an attacker in complete control of the system. The fact that these vulnerabilities were privately disclosed and that we are yet to see any malware that exploit these issues have been considered when assigning the SophosLabs threat rating of Medium, although we do recommend that users apply this patch at their earliest convenience. |
| SophosLabs testing result | N/A |
| Currently known exploits | At the time of writing SophosLabs have not observed any malware attempting to exploit this vulnerability. Should this situation change samples will be analyzed and we will take action as necessary. |
| First sample seen | N/A |
