CVE-2019-1821: Cisco Prime Infrastructure and Evolved Programmable Network Manager Remote Code Execution Vulnerabilities

Security readout for executives and security teams

This vulnerability could let a logged-in remote attacker take over the underlying server running Cisco Prime Infrastructure or EPN Manager with root privileges. The bundle identifies Cisco Prime Infrastructure 3.4 as affected. Because these tools manage network infrastructure, compromise could create broad operational and security risk. Exposure is most likely where Cisco Prime Infrastructure 3.4, or Cisco EPN Manager as covered by Cisco's advisory, is deployed and the administrative web interface is reachable by authenticated users or compromised accounts. Prioritize remediation for internet-reachable or widely accessible management interfaces. Even though active exploitation is not established in the supplied sources, root-level compromise of network management software can affect network visibility, configuration integrity, and business continuity. Mitigation focus: Review Cisco's advisory for affected builds and fixed release guidance.; Upgrade or remediate affected Cisco Prime Infrastructure 3.4 deployments per vendor guidance.; Restrict administrative web interface access to trusted management networks..
