CVE-2018-1218: Dell EMC Dell EMC NetWorker vulnerability

CVE-2018-1218: In Dell EMC NetWorker versions prior to 9.2.1.1, versions prior to 9.1.1.6, 9.0.x, and versions prior to 8....

In Dell EMC NetWorker versions prior to 9.2.1.1, versions prior to 9.1.1.6, 9.0.x, and versions prior to 8.2.4.11, the 'nsrd' daemon causes a buffer overflow condition when handling certain messages. A remote unauthenticated attacker could potentially exploit this vulnerability to cause a denial of service to the users of NetWorker systems.

Security readout for executives and security teams

CVE-2018-1218 is a remote unauthenticated denial-of-service flaw in older Dell EMC NetWorker releases. A crafted message to the nsrd daemon can trigger a buffer overflow and potentially disrupt backup service availability. This matters most where NetWorker supports recovery operations or is reachable from untrusted networks. Exposure is most likely on NetWorker servers running affected versions with the nsrd service reachable over a network. Internet exposure would raise urgency, but the source bundle does not confirm common deployment patterns or default network accessibility. Treat this as a backup-service availability risk. Prioritize exposed or production NetWorker servers because disruption could weaken recovery readiness during an incident. Urgency is lower than confirmed code execution or KEV-listed exploitation, based on the provided evidence. Mitigation focus: Upgrade NetWorker to 9.2.1.1, 9.1.1.6, or 8.2.4.11 or later as applicable.; Move 9.0.x deployments to a fixed supported release.; Restrict nsrd network access to trusted backup infrastructure only..
