EudorIA operational summary

What it means

Priority 70/100

Erlang OTP è interessato da vulnerabilità in versioni precedenti a 27.3.4.18, 28.5.0.7, 29.1.1, 5.2.11.13, 5.5.2.6, 6.0.6, 11.2.12.13, 11.6.0.6, 11.7.7 e 84adefa. L'attacco potrebbe permettere l'esecuzione non autorizzata. La Cyber Centre raccomanda di applicare le patch disponibili.

Why it matters

Le PMI italiane che utilizzano Erlang OTP potrebbero essere esposte a compromissioni di sistemi critici, con rischi per la continuità operativa e la protezione dei dati sensibili. La mancanza di patch potrebbe portare a interruzioni di servizio e violazioni della privacy.

Potential operational benefits

  • Riduzione della superficie esposta alle minacce
  • Miglioramento della sicurezza generale del sistema
  • Riduzione del rischio di interruzioni di servizio
