Security readout for executives and security teams
Plain-English summary
This vulnerability lets a highly privileged local user on Cisco Enterprise NFV Infrastructure Software read files from the underlying operating system. It is not described as remote or unauthenticated. The business concern is exposure of sensitive local system data if an attacker already has significant access to an affected NFVIS device.
Executive priority
Treat this as a moderate-priority infrastructure hygiene issue. It is serious for confidentiality on affected NFVIS devices, but the high-privilege local requirement lowers urgency compared with remote unauthenticated flaws.
Technical view
CVE-2019-1959 covers multiple arbitrary file read issues in Cisco Enterprise NFV Infrastructure Software. CVSS 3.0 is 4.4: local access, low complexity, high privileges required, no user interaction, unchanged scope, high confidentiality impact, no integrity or availability impact. CWE-20 is listed.
Likely exposure
Exposure is likely limited to organizations running Cisco Enterprise NFV Infrastructure Software where users or attackers can obtain high-privileged local access. The provided source bundle does not identify specific affected or fixed versions.
Exploitation context
The sources do not indicate active exploitation, and the CVE is not marked KEV. Exploitation requires authenticated local access with high privileges, so this is mainly a post-access confidentiality risk rather than an initial-entry vulnerability.
Researcher notes
The public bundle lacks version-specific affected ranges and fix details. Use Cisco’s advisory as the controlling source for release applicability. Avoid assuming exploit availability or broader Cisco product impact beyond Cisco Enterprise NFV Infrastructure Software.
Mitigation direction
- Inventory Cisco Enterprise NFV Infrastructure Software deployments.
- Check Cisco’s advisory for affected and fixed NFVIS releases.
- Apply Cisco-recommended updates or mitigations where applicable.
- Restrict local and administrative access to NFVIS devices.
- Review privileged accounts for unnecessary access.
Validation and detection
- Confirm whether any NFVIS deployments exist in the environment.
- Compare installed NFVIS versions with Cisco advisory guidance.
- Review access controls for high-privileged local users.
- Check logs for unusual privileged local activity.
- Confirm remediation status after any vendor-recommended update.
