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? Yes. The attacker sends an HTTP request that includes path traversal sequences (../) to write a file to the webroot, which is unusual and can be detected by a WAF rule matching such sequences in file path parameters. A WAF rule can match ../ sequences in a file path parameter. No tracked WAF vendor has published a rule for this CVE yet, so you would write it yourself.
What a custom rule would match: ../ sequences in a file path parameter
Also consider: patch · custom WAF rule · canonical path validation
Based on an AI reading of the CVE description, and no vendor rule found yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.

Yes. CVE-2023-47246 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-2023-47246?
CVE-2023-47246 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-2023-47246?
Yes. A fix has been recorded for CVE-2023-47246. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
