Summary
MikroTik RouterOS 6.40.5, the SMB service contains a memory corruption vulnerability. Remote, unauthenticated attackers can exploit this issue by sending specially crafted packets, triggering a null pointer dereference. This leads to a Remote Denial of Service (DoS), rendering the SMB service unavailable.
MikroTik RouterOS contains an improper neutralization of argument delimiters in a command vulnerability which allows an attacked to change the trusted RouterOS policy mask, leading to privilege escalation.
MikroTik RouterOS contains a missing authenticaion for critical function vulnerability which allows kernel memory disclosure and denial of service in the btest service.
An API session‑management flaw in products with the MikroTik RouterOS API enabled are vulnerable to a Insufficient Session Expiration vulnerability. This could allow active sessions to retain their previous permission set after inactivity timeouts or user‑group changes. As a result, an authenticated user whose permissions have been reduced may continue accessing information.
