Horizon Alert
Summary of the vulnerability and why it matters
This advisory addresses vulnerabilities in Cisco Nexus Dashboard, a network management platform, stemming from how it processes special commands. While typically managed internally, its networked nature means potential exposure if misconfigured, posing a risk that warrants confirmation of relevance and exposure within your environment.
- Command handling flaw discovered internally.
- Affects critical network management software.
- Confirm relevance and exposure.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this vulnerability by sending a specially crafted command to a Cisco Nexus Dashboard, which lacks proper handling of special characters within commands. This could allow an attacker with some level of access to execute arbitrary commands on the system.
- Entry condition: Network access with some privileges.
- Trigger point: Sending a malicious command.
- Resulting risk: Arbitrary command execution.
Live Threat
Current exploitation, exposure, and threat context
Improper handling of special characters in commands within Cisco Nexus Dashboard could allow an authenticated attacker to execute arbitrary commands on the system. This could affect system operations and potentially expose sensitive system data.
- System commands and data could be affected.
- An authenticated user could trigger vulnerable commands.
- Unauthorized command execution may occur.
Operational Fix
Recommended remediation, mitigation, and detection steps
In real-world scenarios, Cisco Nexus Dashboard deployments commonly fall under the purview of platform or infrastructure teams, with oversight from network and security teams due to its critical management role. The initial practical step is to identify all instances of the Cisco Nexus Dashboard within your environment, determine their reachability, assess their business criticality, and then confirm the accountable owner for each instance to prioritize and plan remediation efforts.
- Platform or infrastructure teams should own.
- Verify dashboard reachability and criticality.
- Plan remediation based on confirmed ownership.
