Netmaker has Hardcoded DNS Secret Key
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for CVE-2023-32077.
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2023-32077 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,636 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Impact
Hardcoded DNS key usage has been found in Netmaker allowing unauth users to interact with DNS API endpoints.
Patches
Issue is patched in 0.17.1, and fixed in 0.18.6+.
If Users are using 0.17.1, they should run "docker pull gravitl/netmaker:v0.17.1" and "docker-compose up -d". This will switch them to the patched users
If users are using v0.18.0-0.18.5, they should upgrade to v0.18.6 or later.
Workarounds
If using 0.17.1, can just pull the latest docker image of backend and restart server.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/gravitl/netmaker, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/gravitl/netmaker to 0.17.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-32077 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2023-32077 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-32077. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
How to detect CVE-2023-32077
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id cve-2023-32077 -u https://target- Template
- Netmaker - Hardcoded DNS Secret Key
- Severity
- high
- Impact
- Unauthenticated attackers can access DNS API endpoints using the hardcoded secret key, potentially manipulating DNS configurations and redirecting WireGuard network traffic in the Netmaker VPN infrastructure.
- Remediation
- Update Netmaker to version 0.17.1 or 0.18.6 or later that removes hardcoded credentials and implements proper authentication for DNS API endpoints.
