Mikrotik RouterOS before 6.44.5 (long-term release tree) is vulnerable to stack exhaustion. By sending a crafted HTTP request, an authenticated remote attacker can crash the HTTP server via recursive parsing of JSON. Malicious code cannot be injected.

Weakness

The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
