CVE-2024-47269: Synology Surveillance Station Disclosure Flaw

CVE-2024-47269 Overview

CVE-2024-47269 is a cleartext transmission of sensitive information vulnerability [CWE-319] affecting the Export Key functionality in Synology Surveillance Station. The flaw allows remote authenticated users with administrator privileges to obtain sensitive information through unspecified vectors. Synology resolved the issue in Surveillance Station versions 9.2.2-11575 and 9.2.2-9575.

The vulnerability requires high privileges to exploit and impacts confidentiality only. While the attack vector is network-based, the requirement for administrator credentials limits the exploitable population. Organizations running affected Surveillance Station deployments should upgrade to the patched releases.

Critical Impact

An authenticated administrator can intercept sensitive key material transmitted in cleartext during the export operation, exposing confidential data to network observers.

Affected Products

• Synology Surveillance Station versions prior to 9.2.2-11575
• Synology Surveillance Station versions prior to 9.2.2-9575
• Surveillance Station Export Key functionality

Technical Details for CVE-2024-47269

Vulnerability Analysis

The vulnerability resides in the Export Key functionality of Synology Surveillance Station. When the application transmits sensitive key material during the export operation, the data travels in cleartext rather than through an encrypted channel. Any actor positioned to observe the network traffic can capture the exported information.

The issue is classified under [CWE-319] Cleartext Transmission of Sensitive Information. Confidentiality impact is high while integrity and availability remain unaffected. Exploitation requires administrator-level authentication on the Surveillance Station instance.

Root Cause

The root cause is the absence of transport-layer protection for key material handled by the Export Key feature. Sensitive data that should be confined to an encrypted channel is instead emitted in a readable form. This design choice exposes the data to passive interception on any segment the traffic traverses.

Attack Vector

An authenticated administrator initiates the Export Key operation. An attacker with the ability to observe traffic between the client and the Surveillance Station instance reads the exported key material from the wire. The attack does not require user interaction beyond the legitimate export action and does not alter system state.

No public proof-of-concept code is available for this vulnerability. Refer to the Synology Security Advisory SA-24-25 for vendor-provided technical detail.

Detection Methods for CVE-2024-47269

Indicators of Compromise

• Unencrypted HTTP traffic containing Surveillance Station Export Key payloads observed in packet captures
• Administrator session activity invoking the Export Key endpoint from unexpected source addresses
• Surveillance Station instances running versions earlier than 9.2.2-11575 or 9.2.2-9575

Detection Strategies

• Inspect network captures for Surveillance Station management traffic that lacks TLS encryption
• Review Surveillance Station audit logs for Export Key operations and correlate with administrator session origins
• Identify Surveillance Station versions across the estate and flag instances below the fixed releases

Monitoring Recommendations

• Enable verbose logging on Surveillance Station for administrator actions, including key export events
• Monitor for anomalous administrator logins, especially from new geographies or service accounts
• Alert when Surveillance Station management interfaces are reachable over plaintext channels

How to Mitigate CVE-2024-47269

Immediate Actions Required

• Upgrade Surveillance Station to version 9.2.2-11575 or 9.2.2-9575, depending on the deployed branch
• Rotate any keys that were previously exported using the vulnerable functionality
• Restrict administrator access to Surveillance Station to trusted networks and accounts

Patch Information

Synology addressed the vulnerability in Surveillance Station 9.2.2-11575 and 9.2.2-9575. Patch details are published in the Synology Security Advisory SA-24-25. Apply the appropriate fixed release for your branch.

Workarounds

• Avoid using the Export Key functionality until the patched version is deployed
• Confine Surveillance Station management traffic to encrypted VPN tunnels or isolated management VLANs
• Enforce multi-factor authentication for all Surveillance Station administrator accounts to reduce credential compromise risk

# Verify Surveillance Station package version on a Synology NAS
synopkg version SurveillanceStation

# Confirm the installed version is at or above the fixed release
# Expected: 9.2.2-11575 or 9.2.2-9575
