The router stores username, salt, and v’s x coordinate, v x, in memory in /rw/store/user.dat.The router generates a 16-byte user salt and calculates the user’s password verifier, v, according to the equation v = ECDH(SHA2(salt | SHA2(username | “:” | password))).A user registers with the system, providing a username and password.This protocol, which is much less prevalent, is defined by the following sequence: User registration Rather, RouterOS employs elliptic curve SRP (EC-SRP), specifically EC-SRP5. However, MikroTik does not implement this SRP protocol. The SRP specification dates back over two decades and mainstream use gained traction in the recent past, highlighted by its use in OpenSSL. Knowledge of the correct password is required to compute the shared secret, so identical secrets indicate successful authentication. SRP is a type of Password Authentication Key Exchange protocol which incorporates the password within key exchange calculations. MikroTik's new authentication process uses a variation of Secure Remote Password (SRP). Margin Research is excited to illuminate the authentication procedure and offer Python proof of concept (POC) implementations for Winbox and MAC Telnet authentication. MikroTik has since failed to detail the new authentication procedure despite user requests for assistance. While enhancing router security, this came as a blow for researchers, network administrators, and tinkerers who used customized tooling with MikroTik proprietary protocols such as MAC Telnet and Winbox.
#Password winbox mikrotik update
In August 2019, MikroTik issued a RouterOS software update to version 6.45.1 which removed plaintext password storage on all routers that upgraded to the new firmware. Februby Ian Dupont and Joe Lothan Posted in:
