MikroTik RouterOS has faced several critical authentication bypass and unauthenticated remote code execution (RCE) vulnerabilities over the years. These flaws often target management interfaces like , or core networking daemons. Major Historical Vulnerabilities Winbox Directory Traversal (CVE-2018-14847)
Management traffic on certain versions defaults to HTTP, allowing on-path attackers to intercept credentials in a Man-in-the-Middle (MITM) attack . mikrotik routeros authentication bypass vulnerability

An attacker can exploit this vulnerability by sending a malicious request to the router's web interface, which can be done using various tools such as curl or a web browser. The request would contain a specially crafted username and password, which would allow the attacker to bypass authentication and gain access to the router's configuration. I I I I'
Attackers used this flaw to download the user.dat file, which contained the plaintext passwords of the router's administrators.
