CVE-2024-45208
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Versa Director SD-WAN orchestration platform which makes use of Cisco NCS application service. Active and Standby Directors communicate over TCP ports 4566 and 4570 to exchange High Availability (HA) information using a shared password. Affected versions of Versa Director bound to these ports on all interfaces. An attacker that can access the Versa Director could access the NCS service on port 4566 and exploit it to perform unauthorized administrative actions and perform remote code execution. Customers are recommended to follow the hardening guide. Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceVersa Director's embedded Cisco NCS application service binds to TCP ports 4566 and 4570 on all network interfaces rather than仅限于内部HA通信接口。攻击者只要能访问这些暴露的端口，即可利用共享密码进行未授权管理操作并实现远程代码执行。

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Versa Director is installedCheck if Versa Director software is present on the system by reviewing installed packages or the application directory structure (typically under /opt/versa or similar vendor directories)Affected if Versa Director software is found on the system
-
Identify if NCS service is enabledReview the Versa Director configuration or running processes to determine if the embedded Cisco NCS application service is enabled and runningAffected if The NCS service is running or enabled on the system
-
Check if port 4566 is listeningRun 'netstat -tlnp' or 'ss -tlnp' to verify if TCP port 4566 is bound and listening. Use 'ss -tlnp | grep 4566' or check the listening address (0.0.0.0 vs. internal interface IP)Affected if Port 4566 is bound to 0.0.0.0 or a non-internal IP address, indicating it is exposed beyond HA interfaces
-
Check if port 4570 is listeningRun 'netstat -tlnp' or 'ss -tlnp' to verify if TCP port 4570 is bound and listening. Use 'ss -tlnp | grep 4570' or check the listening address (0.0.0.0 vs. internal interface IP)Affected if Port 4570 is bound to 0.0.0.0 or a non-internal IP address, indicating it is exposed beyond HA interfaces
-
Verify network accessibility of these portsConfirm whether ports 4566 and 4570 are reachable from network segments other than the designated internal HA interface by reviewing firewall rules, ACLs, or by attempting a connection test from an external hostAffected if Ports 4566 and 4570 are accessible from non-HA network segments
If the NCS service is running and ports 4566 or 4570 are bound to all interfaces (0.0.0.0) or accessible from non-internal networks, the system is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
