CVE-2014-3307: The DHCP client implementation in Universal Small Cell firmware on Cisco Small Cell products allows remote...

Security readout for executives and security teams

A flaw in Cisco Universal Small Cell firmware's DHCP client could let a remote attacker make affected Cisco Small Cell devices run arbitrary commands using crafted DHCP messages. A basic network configuration protocol could become a control path for the device. The bundle does not specify affected versions, patch status, or observed exploitation. Exposure is limited to environments running Cisco Small Cell products with Universal Small Cell firmware. Risk depends on whether untrusted or attacker-controlled DHCP traffic can reach the device's DHCP client. The bundle does not identify exact models or firmware versions. Prioritize if Cisco Small Cell devices remain deployed, especially on networks where DHCP traffic is not tightly controlled. Remote command execution on telecom edge equipment can create operational and security risk, but urgency should be confirmed against actual deployed models and Cisco guidance. Mitigation focus: Check Cisco's advisory for affected models, firmware versions, and supported fixes.; Upgrade or replace affected Cisco Small Cell firmware per vendor guidance.; Restrict DHCP service paths to trusted network segments only..
