CVE-2018-13294
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 · uneditedInformation exposure vulnerability in SYNO.Personal.Profile in Synology Application Service before 1.5.4-0320 allows remote authenticated users to obtain sensitive system information via the uid parameter.
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 confidenceInformation disclosure vulnerability in the SYNO.Personal.Profile component of Synology Application Service allows authenticated remote attackers to retrieve sensitive system information by manipulating the uid parameter in requests.

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.
-
Confirm Synology Application Service is installedLog into DSM (DiskStation Manager) and open Package Center. Look for 'Synology Application Service' in the installed packages list. Alternatively, check via SSH using 'cat /etc/synoinfo.conf' or listing installed Synology packages.Affected if The package is installed and appears in the package list
-
Verify the installed version numberIn DSM Package Center, click on Synology Application Service and view the version information. Compare the version string (e.g., 1.5.x-xxxx) against 1.5.4-0320. The first three numbers must be less than 1.5.4, or equal to 1.5.4 but with a build number lower than 0320.Affected if The version is below 1.5.4-0320 (for example, 1.5.3-0285 or 1.5.4-0315)
-
Check if SYNO.Personal.Profile API endpoint is accessibleSend an HTTP GET request to the API endpoint. On a typical Synology NAS, this would be: http://[NAS-IP]:5000/webapi/SYNO.Personal.Profile/1.0/?api=SYNO.Personal.Profile&method=get&version=1. Check if the endpoint responds (with or without authentication).Affected if The endpoint returns any response (even an authentication error indicates the component is exposed)
-
Confirm authentication is required for the profile endpointAttempt an unauthenticated request to the SYNO.Personal.Profile API. If the service returns user profile data or system information without requiring valid credentials, the vulnerability is present. A proper response would be an authentication error.Affected if The endpoint returns sensitive information (user profiles, system details) without providing valid authentication credentials
The environment is affected if Synology Application Service is installed with a version lower than 1.5.4-0320 and the SYNO.Personal.Profile API endpoint is accessible and returns information without proper authorization.

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.
From vendor data1.5.4-0320
Upgrade Synology Application Service to version 1.5.4-0320 or later to resolve the information exposure. Verify that only authorized users have access to the affected service.
