CVE-2024-47271: Synology Surveillance Station Exposure

CVE-2024-47271 Overview

CVE-2024-47271 is an insufficiently protected credentials vulnerability in the IPSpeaker component of Synology Surveillance Station. The flaw affects versions prior to 9.2.2-11575 and 9.2.2-9575. Authenticated remote users with administrator privileges can obtain sensitive information through unspecified vectors. The vulnerability is tracked under CWE-522: Insufficiently Protected Credentials.

Synology disclosed the issue in advisory Synology_SA_24_25. The vulnerability requires high privileges and does not impact integrity or availability. It does expose confidential credential material that attackers can repurpose for lateral movement to integrated IP speaker devices.

Critical Impact

Administrator-level attackers can extract stored IPSpeaker credentials from Synology Surveillance Station, enabling unauthorized access to integrated audio broadcasting hardware.

Affected Products

• Synology Surveillance Station versions prior to 9.2.2-11575
• Synology Surveillance Station versions prior to 9.2.2-9575
• IPSpeaker component within Surveillance Station

Technical Details for CVE-2024-47271

Vulnerability Analysis

The vulnerability resides in how the IPSpeaker component of Synology Surveillance Station stores or transmits credentials used to authenticate to networked IP speaker devices. Surveillance Station integrates with IP speakers to broadcast audio alerts tied to camera events. These integrations require persistent credentials that the application must store and retrieve.

When credentials are not adequately protected through encryption, access controls, or masking in administrative interfaces, users holding administrator sessions can retrieve them in usable form. The vulnerability is exploitable over the network but requires a valid administrative session, which limits the population of potential attackers.

The exposed credentials enable secondary attacks against the IP speaker infrastructure itself. Attackers can hijack broadcast capabilities, suppress security audio alerts, or pivot into adjacent network segments where the speakers reside.

Root Cause

The root cause is improper credential protection within the IPSpeaker integration code path. CWE-522 covers scenarios where applications transmit or store authentication data using methods susceptible to unauthorized interception or retrieval. Synology has not disclosed the precise storage mechanism in the public advisory.

Attack Vector

The attack vector requires network access to the Surveillance Station management interface and valid administrator credentials. Once authenticated, the attacker invokes the affected IPSpeaker functionality to retrieve stored credentials. The specific request paths and parameters are not disclosed in the public advisory.

No exploitation has been observed in the wild. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. Public proof-of-concept code is not available.

Detection Methods for CVE-2024-47271

Indicators of Compromise

• Unexpected administrator logins to Surveillance Station from unfamiliar source IP addresses or at unusual hours
• Configuration changes to IPSpeaker integration entries not associated with planned administrative work
• Outbound authentication attempts from IP speakers originating from hosts other than the Surveillance Station server

Detection Strategies

• Audit Synology DSM and Surveillance Station logs for administrator account activity, focusing on IPSpeaker configuration views and exports
• Monitor network traffic between Surveillance Station and IP speakers for authentication anomalies or credential reuse from unauthorized endpoints
• Compare installed Surveillance Station versions against the patched releases 9.2.2-11575 and 9.2.2-9575 across the fleet

Monitoring Recommendations

• Forward DSM authentication and package logs to a centralized logging platform for correlation against baseline administrator behavior
• Alert on creation of new administrator accounts or privilege elevation events on Synology appliances hosting Surveillance Station
• Track IP speaker administrative sessions and flag logins that do not originate from the Surveillance Station host

How to Mitigate CVE-2024-47271

Immediate Actions Required

• Upgrade Surveillance Station to version 9.2.2-11575 or 9.2.2-9575 or later, matching the appropriate DSM release branch
• Rotate all credentials configured in IPSpeaker integrations after patching, treating them as exposed
• Review the Surveillance Station administrator account roster and remove unused or shared accounts

Patch Information

Synology released fixed builds of Surveillance Station in versions 9.2.2-11575 and 9.2.2-9575. Apply the update through DSM Package Center or download directly from the vendor. Consult the Synology Security Advisory Synology_SA_24_25 for the authoritative remediation guidance.

Workarounds

• Restrict administrative access to Surveillance Station to a small, named set of accounts protected by multi-factor authentication
• Place Surveillance Station and IP speakers on a segmented management VLAN with strict ingress controls until patching is complete
• Disable the IPSpeaker integration entirely in environments where it is not actively used

# Verify the installed Surveillance Station version on a Synology DSM appliance
synopkg version SurveillanceStation

# Confirm patched build is present (expected output: 9.2.2-11575 or 9.2.2-9575 or later)
