The default configuration of Microsoft Windows 7 immediately prefers a new IPv6 and DHCPv6 service over a currently used IPv4 and DHCPv4 service upon receipt of an IPv6 Router Advertisement (RA), and does not provide an option to ignore an unexpected RA, which allows remote attackers to conduct man-in-the-middle attacks on communication with external IPv4 servers via vectors involving RAs, a DHCPv6 server, and NAT-PT on the local network, aka a "SLAAC Attack." NOTE: it can be argued that preferring IPv6 complies with RFC 3484, and that attempting to determine the legitimacy of an RA is currently outside the scope of recommended behavior of host operating systems
CVE-2011-1652 is a security vulnerability that . Impacting 1 product from microsoft organizations running these solutions should prioritize assessment and patching.
Documented in 2011, this vulnerability occurred amid the cloud computing expansion era, where traditional network perimeter security models were being reevaluated. Organizations were transitioning from isolated infrastructure to interconnected systems, creating new attack surfaces that vulnerabilities like this could exploit.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For microsoft's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
