CVE-2015-0739: The Lights-Out Management (LOM) implementation in Cisco FireSIGHT System Software 5.3.0 on Sourcefire 3D Se...

Security readout for executives and security teams

This CVE concerns Cisco Sourcefire 3D Sensor devices running FireSIGHT System Software 5.3.0. An authenticated remote user could upload arbitrary files through Lights-Out Management, affecting the Baseboard Management Controller. The source bundle does not provide CVSS, a named fix, or evidence of active exploitation. Exposure is most likely where Cisco Sourcefire 3D Sensors run FireSIGHT System Software 5.3.0 and LOM/BMC management is reachable by authenticated users. The provided affected-product metadata is incomplete, so inventory confirmation is required. Treat this as an inventory and access-control priority. Urgency rises if affected sensors are still in service, LOM is exposed beyond a restricted management network, or shared administrator credentials are used. Mitigation focus: Check Cisco advisory and Bug ID CSCus87938 for fixed releases or official mitigations.; Restrict LOM/BMC access to trusted management networks only.; Remove unnecessary management accounts and enforce strong authentication controls..
