A vulnerability in MikroTik Version 6.38.5 could allow an unauthenticated remote attacker to exhaust all available CPU via a flood of UDP packets on port 500 (used for L2TP over IPsec), preventing the affected router from accepting new connections; all devices will be disconnected from the router and all logs removed automatically.

Exploit prediction (EPSS)

4.21% probability of exploitation in the next 30 days, higher than 91% of all scored CVEs.
