Severity, decoded
CVSS 3.1Exploitable over the network, with no privileges and no user interaction, leading to full loss of confidentiality.
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 requiredNo account or login is needed.None
- 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 impactData cannot be changed by the attacker.None
- Availability impactThe component keeps working normally.None
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NAttackers are exploiting this in the wild.
Attackers can script the attack end to end and hit many targets at once.
