The Winsock WSAIoctl API in Microsoft Windows Server 2008, as used in ISC BIND 9.6-ESV before 9.6-ESV-R10-P1, 9.8 before 9.8.6-P1, 9.9 before 9.9.4-P1, 9.9.3-S1, 9.9.4-S1, and other products, does not properly support the SIO_GET_INTERFACE_LIST command for netmask 255.255.255.255, which allows remote attackers to bypass intended IP address restrictions by leveraging misinterpretation of this netmask as a 0.0.0.0 netmask.

Security readout for executives and security teams

This CVE can let a remote party bypass IP-based access restrictions in affected ISC BIND deployments on Microsoft Windows Server 2008. The issue comes from Windows misreporting a 255.255.255.255 netmask as 0.0.0.0, which can make BIND interpret restricted interfaces too broadly. Most likely exposure is legacy ISC BIND running on Microsoft Windows Server 2008, especially versions listed as before 9.6-ESV-R10-P1, 9.8.6-P1, or 9.9.4-P1. The source bundle does not confirm broader products beyond the CVE phrase “other products.” Prioritize if legacy Windows Server 2008 DNS infrastructure still runs ISC BIND with IP-based restrictions. The business risk is unauthorized access to services believed restricted by IP ACLs, but urgency is tempered by limited evidence and no confirmed active exploitation in the bundle. Mitigation focus: Inventory BIND deployments running on Windows Server 2008.; Upgrade affected ISC BIND versions to the fixed patch releases named by ISC.; Review ISC advisories AA-01062 and AA-01063 for vendor-specific guidance..
