CVE-2022-27619
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCleartext transmission of sensitive information vulnerability in authentication management in Synology Note Station Client before 2.2.2-609 allows man-in-the-middle attackers to obtain sensitive information via unspecified vectors.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSynology Note Station Client before version 2.2.2-609 transmits authentication credentials and potentially other sensitive information in cleartext (unencrypted) format. A man-in-the-middle attacker on the network path between client and server can intercept these credentials by capturing network traffic.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Synology Note Station Client versionOn Windows, open Control Panel > Programs and Features and locate Synology Note Station in the list to view the installed version. On macOS, navigate to the application in Finder, right-click and select Get Info to view the version. On mobile (iOS/Android), go to the app store or device settings > Apps > Note Station to see the version number.Affected if The installed version is lower than 2.2.2-609
-
Compare version against affected rangeTake the version number you identified and compare it numerically to 2.2.2-609. Note that versions like 2.2.2-600, 2.2.1, or any build before 609 are all in the affected range.Affected if The client version is less than 2.2.2-609 (for example, 2.2.2-500 or 2.2.1-123)
-
Assess network exposure riskDetermine whether the client connects to the Synology server over networks where a man-in-the-middle attack is possible, such as public WiFi hotspots, untrusted corporate networks, or shared network environments.Affected if The vulnerable client version connects to the server over any untrusted or public network where an attacker could intercept network traffic
A user is affected if the Synology Note Station Client version is below 2.2.2-609 AND the client communicates with the server over a network where MITM interception is feasible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.2.2-609
Upgrade Synology Note Station Client to version 2.2.2-609 or later. Until upgraded, avoid using the client over untrusted networks (e.g., public WiFi) where MITM attacks are feasible.
2.2.2-609 or later
- 1. Open Synology Note Station Client on your system
- 2. Navigate to Help > About to verify the current version number
- 3. Uninstall the current version of Synology Note Station Client
- 4. Download Note Station Client version 2.2.2-609 or later from the official Synology download center at www.synology.com
- 5. Install the updated Note Station Client version
