Exploitation outlook

EPSS (FIRST.org) estimates each CVE’s probability of exploitation in the next 30 days — here is the CSIRTS.com read on those numbers.

• Moderate exploitation riskCVE-2020-21811.1% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 62% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2020-21820.88% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 56% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2020-21830.85% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 55% of all EPSS-scored CVEs.
• Elevated exploitation riskCVE-2020-218444.5% 30-day exploitation probability — well above the norm. Schedule remediation this cycle. Riskier than 99% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2020-21850.69% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 50% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2020-21860.64% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 48% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2020-21870.41% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 34% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2020-21880.65% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 48% of all EPSS-scored CVEs.
• Moderate exploitation riskCVE-2020-21892.3% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 82% of all EPSS-scored CVEs.
