Mikrotik RouterOS before 6.42.7 and 6.40.9 is vulnerable to a stack exhaustion vulnerability. An authenticated remote attacker can crash the HTTP server via recursive parsing of JSON.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
