Security readout for executives and security teams
Plain-English summary
Cisco Nexus Dashboard has privilege escalation flaws that could let someone who already has local authenticated rescue-user access gain root privileges. This is not a remote internet drive-by issue, but it is serious for environments where Nexus Dashboard manages sensitive network operations.
Executive priority
Treat this as a moderate-priority infrastructure control issue. It is unlikely to be exploited without prior access, but successful exploitation grants root control on a network-management platform, which can increase operational and security impact after credential compromise.
Technical view
The CVE describes multiple Cisco Nexus Dashboard vulnerabilities caused by insufficient input validation during CLI command execution. An authenticated local attacker using the rescue-user account could execute malicious CLI input and elevate privileges to root. CVSS 3.1 is 6.0 with local access and high privileges required.
Likely exposure
Exposure is limited to organizations running Cisco Nexus Dashboard where an attacker can authenticate locally as rescue-user. Risk is higher if rescue-user credentials are shared, weakly controlled, or available to broad operational staff.
Exploitation context
The provided sources do not state active exploitation, and KEV is false. Exploitation requires authenticated local access as rescue-user, reducing broad exposure but creating meaningful insider, credential compromise, and post-compromise risk.
Researcher notes
The supplied CVE record maps CWE-367, while the description emphasizes insufficient input validation in CLI command execution. Fixed versions and specific mitigations are not included in the prompt bundle, so validation should rely on Cisco’s advisory rather than inferred product behavior.
Mitigation direction
- Identify Cisco Nexus Dashboard deployments and installed versions.
- Review Cisco advisory for affected and fixed release guidance.
- Apply Cisco-recommended updates or mitigations where applicable.
- Restrict rescue-user and local CLI access to trusted operators.
- Monitor administrative activity for unexpected privilege changes.
Validation and detection
- Confirm whether Cisco Nexus Dashboard is deployed in the environment.
- Compare installed releases with Cisco advisory affected-release information.
- Audit who can use rescue-user or local CLI access.
- Review logs for unusual CLI execution or root-level activity.
- Document remediation status, owners, and accepted exceptions.
