How to verify CVE-2021-32675

Confirm whether your systems are actually affected — run the exact detection check below (Nuclei command or OpenVAS NVT). Detection only; it does not exploit.

How to verify this vulnerability

Scanner data tells you how to confirm whether your systems are actually affected — not just that the CVE exists. Run a Nuclei template against your target for a yes/no answer in seconds.

What's a Nuclei template? Nuclei is a free, open-source scanner. A template is a small YAML rule that probes a target and reports whether it's vulnerable. Runs locally, no agent.
1 · AUTOMATEDDetection command
nuclei -t CVE-2021-32675.yaml -u your-target:port -rl 50 -timeout 10

Community template — download the YAML from GitHub first, then run the command against your own host.
