CVE-2019-13954
Status: ModifiedMedium (6.5)—
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.
CVSS
- Version: 3.0
