Severity, decoded
CVSS 3.1Exploitable over the network, with high privileges and no user interaction, leading to full loss of confidentiality, integrity and availability.
How the score is built
- Attack vectorAn attacker can reach it over the internet; no access to your network needed.Network
- Attack complexityNo special conditions are needed; the attack works reliably.Low
- Privileges requiredThe attacker needs an administrator-level account.High
- User interactionNo one has to click or open anything; the attack works on its own.None
- ScopeThe damage stays within the vulnerable component.Unchanged
- Confidentiality impactAn attacker can read all data the affected component holds, or the most sensitive parts of it.High
- Integrity impactAn attacker can change any data or files the affected component protects.High
- Availability impactAn attacker can take the component down completely or keep it from serving anyone.High
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HAttackers are exploiting this in the wild.
At least one step needs hands-on work, which slows mass attacks.
A successful attack gives full control over the affected software or all of its data.

Vendor statements
QuotedCloudflareWAF Managed Rules
The CVE predates the oldest entry in this vendor's public feed, so a rule may exist that we cannot see.
AWSAWS WAF Managed Rules
We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. AWS often describes a vulnerability without naming its CVE (for example "Log4j"). We count only entries that name the CVE, so AWS coverage is understated.
Microsoft AzureFront Door and Application Gateway WAF (DRS)
We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. The rule tables name CVEs but carry no dates, so Azure is left out of every time-to-rule figure.
Google CloudCloud Armor preconfigured WAF rules
The CVE predates the oldest entry in this vendor's public feed, so a rule may exist that we cannot see.

OWASP CRSCore Rule Set (open source, used inside many WAFs)
We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. CRS rarely names CVEs: it relies on generic detections. Our own lab measures what it actually blocks.
