A buffer overflow was found in the MikroTik RouterOS SMB service when processing NetBIOS session request messages. Remote attackers with access to the service can exploit this vulnerability and gain code execution on the system. The overflow occurs before authentication takes place, so it is possible for an unauthenticated remote attacker to exploit it. All architectures and all devices running RouterOS before versions 6.41.3/6.42rc27 are vulnerable.

Cross-site request forgery (CSRF) vulnerability in MikroTik RouterOS 5.0 and earlier allows remote attackers to hijack the authentication of administrators for requests that change the administrator password via a request in the status page to /cfg.
