SMB Signing Not Required

Category SECURITY_MISCONFIGURATION
Base Score 1.0

Description

The SMB server does not require signing

Impact

SMB signing is a security feature in the SMB protocol that enables SMB clients and servers to validate the authenticity and integrity of communication. When SMB signing is not required, it is possible for attackers to conduct man-in-the-middle attacks that intercept, modify, and relay communication. This can lead to attackers gaining domain account privileges and host access.
