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? No. Weak encryption strength is a configuration problem, not a malicious request, so a WAF has nothing to block.

Also consider: upgrade

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-2017-1000486 being exploited?

Yes. CVE-2017-1000486 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-2017-1000486?

CVE-2017-1000486 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-2017-1000486?

Not known from our data. No patch reference has been recorded for CVE-2017-1000486, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.

What does CVE-2017-1000486 affect?

CVE-2017-1000486 affects primetek:primefaces. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
