Security readout for executives and security teams
Plain-English summary
CVE-2011-2007 is a remote denial-of-service issue in Microsoft Host Integration Server. Crafted TCP or UDP traffic can make the SNA Server service stop responding, disrupting host integration workloads that depend on HIS.
Executive priority
Treat as a business-continuity risk for legacy host integration. Prioritize if HIS supports critical operations or is reachable beyond tightly controlled internal networks.
Technical view
The flaw is described as an “Endless Loop DoS in snabase.exe” affecting Microsoft HIS 2004 SP1, 2006 SP1, 2009, and 2010. The available sources identify remote TCP or UDP traffic as the trigger and SNA Server service outage as the impact.
Likely exposure
Exposure is most likely in legacy environments still running Microsoft Host Integration Server for mainframe or host connectivity. Systems with HIS services reachable from untrusted networks face higher availability risk.
Exploitation context
The source bundle does not cite active exploitation, and KEV status is false. Public evidence provided supports remote denial of service, not code execution, data theft, or privilege escalation.
Researcher notes
Evidence is limited to CVE, OVAL, and Microsoft bulletin references. No CVSS, CWE, exploit status, affected CPEs, or detailed patch state were provided in the bundle.
Mitigation direction
- Review Microsoft MS11-082 guidance for the applicable security update.
- Restrict untrusted TCP and UDP access to HIS/SNA services.
- Prioritize retirement or isolation of unsupported HIS deployments.
- Monitor SNA Server service health and unexpected restarts.
- Use network controls around legacy host integration segments.
Validation and detection
- Inventory systems running Microsoft Host Integration Server.
- Confirm versions: 2004 SP1, 2006 SP1, 2009, or 2010.
- Verify whether MS11-082 remediation is installed or otherwise addressed.
- Review service logs for SNA Server outages or hangs.
- Confirm HIS services are not exposed to untrusted networks.
