Vulnerability Title
MikroTik RouterOS WinBox split-principal authentication bypass allows privilege escalation
Vulnerability Description
An incorrect authorization vulnerability in the WinBox
authentication flow of MikroTik RouterOS allows a remote authenticated attacker
with credentials for a low-privilege account permitted to use WinBox to obtain
the authorization policy of a different existing account. The stage-one EC-SRP
challenge and proof are verified using the attacker's account, while the
independently supplied stage-two username is used to install the target
account's privileges. By specifying a higher-privilege account such as admin, a
low-privilege user can obtain a full administrative session without knowing the
target account's password and can use that session to increase the privileges
of the attacker's own account.
