CVE-2019-13954
Mikrotik RouterOS before 6.44.5 (long-term release tree) is vulnerable to memory exhaustion.
Does this matter?
Lower severity and a low EPSS score (4.26%). Track it; it rarely justifies an emergency change on its own.
Description
Mikrotik RouterOS before 6.44.5 (long-term release tree) is vulnerable to memory exhaustion. By sending a crafted HTTP request, an authenticated remote attacker can crash the HTTP server and in some circumstances reboot the system. Malicious code cannot be injected.
