CVE-2013-1302: Microsoft Communicator 2007 R2, Lync 2010, Lync 2010 Attendee, and Lync Server 2013 do not properly handle...

Security readout for executives and security teams

This is a remote code execution issue in legacy Microsoft Communicator and Lync products. A malicious invitation could trigger unsafe memory use and allow attacker-controlled code to run. Organizations still operating these products should treat this as serious legacy exposure and verify MS13-041 remediation. Exposure is most likely in organizations retaining legacy Microsoft Communicator or Lync deployments, clients, attendees, or server components. Modern estates may only be affected through unmanaged endpoints, archived systems, lab environments, or untracked legacy collaboration infrastructure. Prioritize this where legacy Lync or Communicator remains in production. The business risk is remote code execution through normal collaboration workflows, but urgency depends on whether these older products are still present and reachable. Mitigation focus: Apply Microsoft MS13-041 updates where applicable.; Check Microsoft guidance for exact affected builds and prerequisites.; Inventory and remove unsupported Communicator or Lync installations..
