Fix and mitigation

WAF and other mitigations

Can a WAF block it? Partly. The bug can be reached over the network, so generic WAF rules may stop some attacks. Its weakness type is unknown, so we cannot be more precise.

Also consider: patch

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-2007-2447 being exploited?

Not confirmed. CVE-2007-2447 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 50% probability of exploitation in the next 30 days.

How severe is CVE-2007-2447?

CVE-2007-2447 is rated Medium with a CVSS score of 6.0. 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-2007-2447?

Yes. A fix has been recorded for CVE-2007-2447. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.

What does CVE-2007-2447 affect?

CVE-2007-2447 affects samba:samba. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.

Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
