The vulnerable function does not properly validate the length of the session ID. By overwriting a specific return address on the stack, the attacker can control the instruction pointer. According to public proof-of-concept (PoC) code released on GitHub in late 2023, the exploit uses ROP (Return-Oriented Programming) to bypass ASLR (Address Space Layout Randomization) — which MikroTik implements weakly in older versions.
If you are a network administrator, managed service provider (MSP), or security researcher, you have likely seen this number paired with warnings of remote code execution (RCE) and privilege escalation. But what exactly is the "64710 exploit"? Is it a zero-day? A myth? A mislabeled CVE? mikrotik 64710 exploit
An attacker sends a specially crafted LOGIN_REQUEST packet to port 8291 (WinBox) of the target MikroTik router. No credentials are provided. Instead, the packet contains a malformed username field with a predetermined length (e.g., 256 bytes) that triggers a stack-based buffer overflow in the session_manager process. The vulnerable function does not properly validate the
