CVE-2007-5580: Buffer overflow in a certain driver in Cisco Security Agent 4.5.1 before 4.5.1.672, 5.0 before 5.0.0.225, 5...

Security readout for executives and security teams

This flaw affects older Cisco Security Agent installations on Windows. A crafted SMB network packet could trigger a buffer overflow in a system driver and allow arbitrary code execution. Business risk is highest where vulnerable agents remain on Windows hosts reachable over SMB ports 139 or 445. Likely exposure is limited to legacy Windows systems still running affected Cisco Security Agent builds. Exposure increases when SMB is reachable from untrusted networks or broad internal segments. The bundle does not identify non-Windows products or modern Cisco products as affected. Prioritize remediation if legacy Cisco Security Agent remains deployed on Windows servers or workstations with SMB exposure. This is old, but the impact is severe enough that stale installations should be found and retired or upgraded quickly. Mitigation focus: Upgrade affected Cisco Security Agent builds to the fixed versions named by Cisco/CVE sources.; Restrict TCP 139 and 445 exposure to trusted networks only.; Remove unsupported Cisco Security Agent deployments where upgrade is not possible..
