CVE-2023-37249
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 · uneditedInfoblox NIOS through 8.5.1 has a faulty component that accepts malicious input without sanitization, resulting in shell access.
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 confidenceInfoblox NIOS versions through 8.5.1 contain a command injection vulnerability in a faulty component that fails to sanitize user input, allowing authenticated attackers to execute arbitrary shell commands and gain shell access to the underlying system.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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.
-
Identify NIOS versionAccess the NIOS admin interface and navigate to Help > About, or run 'show version' via CLI. Alternatively, check the banner or system information page.Affected if The installed version is 8.5.2 or lower (any version through 8.5.1 listed as affected).
-
Verify management interface exposureReview network firewall rules or access lists restricting the NIOS management interface (port 443/HTTPS and port 22/SSH). Check if the interface is bound to a public IP or accessible from untrusted networks.Affected if The management interface is reachable from untrusted or external IP addresses.
-
Audit for unauthorized shell accessRun 'show processes' or 'show sessions' via NIOS CLI to list active or recent administrative sessions. Check for unexpected user accounts or session anomalies.Affected if Unexpected active sessions, unknown users, or sessions originating from unauthorized IP addresses exist.
-
Inspect for suspicious processes or artifactsIf access to the underlying Linux shell is available, run commands like 'ps aux' or check /tmp and /var/tmp for unexpected scripts or executables. Look for unfamiliar cron jobs.Affected if Unknown processes, scripts, or cron jobs are present on the system.
-
Review audit and access logsExamine NIOS logs for command injection patterns, such as unusual API calls, unexpected command execution, or authentication from unexpected sources. Check /var/log/messages or the NIOS audit log if accessible.Affected if Logs contain suspicious commands, unexpected administrative actions, or indicators of prior exploitation.
You are affected if your NIOS version is 8.5.2 or lower AND the management interface is accessible to untrusted users, or if you detect unexpected sessions, processes, or log entries indicating compromise.

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.
dbcve · scopedApply the vendor-supplied patch or upgrade to a fixed NIOS version. If immediate patching is not feasible, restrict network access to the NIOS management interface to trusted administrative IPs and monitor for indicators of compromise.
Upgrade to NIOS 8.5.3 or latest stable release
- Check current NIOS version via 'show version' command or admin console
- Contact Infoblox support or visit official support portal to obtain the latest security patch
- Backup current NIOS configuration before applying update
- Apply upgrade to NIOS version 8.5.3 or later which contains the security fix
- Verify upgrade successful and system正常运行
- Confirm vulnerability is resolved through version check
