Summary
Triage
The summary, impact and action text on this page are written by our AI analysis pipeline, or taken from the NVD description when a CVE was imported from NVD. They are not the vendor's wording: check them against the sources. A longer AI executive summary and technical analysis are generated for signed-in accounts on the Max plan.

Fix and mitigation
WAF and other mitigations
Can a WAF block it? Partly. Command injection puts shell syntax into the request. WAF rules catch common shell commands but miss encoded or unusual payloads.
Also consider: input validation · RASP
Based on the weakness type only; no CVE-specific evidence yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.

Common questions
Is CVE-2016-1555 being exploited?
Yes. CVE-2016-1555 appears in CISA's Known Exploited Vulnerabilities catalog, which means exploitation in the wild has been confirmed and reported. Treat it as active rather than theoretical, and patch it ahead of higher-scoring vulnerabilities that carry no exploitation evidence.
How severe is CVE-2016-1555?
CVE-2016-1555 is rated Critical with a CVSS score of 9.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2016-1555?
Yes. A fix has been recorded for CVE-2016-1555. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2016-1555 affect?
CVE-2016-1555 affects netgear:wnap320_firmware, netgear:wndap350_firmware, netgear:wndap360_firmware, netgear:wndap210v2_firmware, and 3 further products or versions. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
