Mikrotik Routeros Authentication Bypass Vulnerability Cracked [hot]

Identified as , this vulnerability stems from a critical flaw in how RouterOS validates digital certificates. This design weakness allows any certificate authority present in the router's system-wide trust store to be trusted in any context. An attacker with a valid certificate from a public CA, such as Let's Encrypt, could use it to bypass authentication on several crucial services, including CAPsMAN, OpenVPN, and Dot1X .

When exploit proof-of-concepts (PoCs) are published or "cracked" in the wild, malicious actors quickly weaponize them into automated scanners. These scanners search the public internet for unpatched, exposed management ports to gain unauthorized administrative access.
