CVE-2018-7445

Severity CVSS v4.0:
Pending analysis
Type:
CWE-119 Buffer Errors
Publication date:
19/03/2018
Last modified:
03/04/2025

Description

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.
