Security Restriction Bypass Vulnerability in Synology DiskStation Manager 

Indian – Computer Emergency Response Team (https://www.cert-in.org.in)

Severity Rating: HIGH

Software Affected

DSM version prior to 7.3.1-86003-1

DSM version prior to 7.2.2-72806-5

Overview

A vulnerability has been identified in Synology DiskStation Manager (DSM), which could allow a remote attacker to bypass security restrictions on the targeted system.

Target Audience:

Users and administrators of affected Synology DiskStation Manager (DSM) installations.

Risk Assessment:

Risk of unauthorized access and sensitive information disclosure.

Impact Assessment:

Exploitation could allow disclosure of sensitive user information.

Description

Synology DiskStation Manager (DSM) is a Linux-based operating system that provides a centralized platform for managing storage, files, applications, and services on Synology NAS devices.

The vulnerability exists due to a flaw in the authentication logic of DSM, where knowledge of a valid LDAP distinguished name (DN) may cause the system to incorrectly treat an unauthenticated request as authenticated. This improper handling can allow an attacker to bypass intended security restrictions.

Successful exploitation of the vulnerability could allow a remote attacker to trigger security restriction bypass on the targeted system.
