Microsoft Windows Server Message Block Client Remote Code Execution Vulnerability

Risk

High

Date Discovered

June 14, 2011

Description

Microsoft Windows is prone to a remote code-execution vulnerability. The issue affects the Microsoft Server Message Block (SMB) client. An attacker can exploit this issue by sending a specially crafted SMB response to the affected application. Successfully exploiting this issue allows an attacker to execute arbitrary code in the context of the application, which may aid the attacker in taking complete control of an affected system.

Recommendations

Run all software as a nonprivileged user with minimal access rights.

To mitigate the impact of a successful exploit, run the affected application as a user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.

Do not use client software to access unknown or untrusted hosts from critical systems.

Do not use client software to connect to servers of unknown or questionable integrity.

Implement multiple redundant layers of security.

Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploit attempts of memory-corruption vulnerabilities.
