Security readout for executives and security teams
Plain-English summary
This Synology Application Service flaw can let a logged-in remote user retrieve sensitive system information. It is not described as a full system compromise, but exposed system details can support reconnaissance and later attacks. The published CVSS score is 4.3, so business urgency is moderate and mainly depends on who can authenticate to affected Synology services.
Executive priority
Handle in normal patching cadence unless affected Synology services are broadly reachable by untrusted authenticated users. Prioritize faster remediation for internet-facing or partner-accessible deployments because the disclosed data may help attackers plan follow-on activity.
Technical view
CVE-2018-13294 is a CWE-200 information exposure issue in SYNO.Personal.Profile before Synology Application Service 1.5.4-0320. A remote authenticated user can obtain sensitive system information through the uid parameter. The CVSS v3.0 vector is AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N.
Likely exposure
Exposure is limited to Synology environments running Application Service versions before 1.5.4-0320. Risk increases where Synology services are reachable over a network by many users, shared accounts, contractors, or other low-trust authenticated users.
Exploitation context
The source bundle does not show CISA KEV listing or other evidence of active exploitation. Exploitation requires authentication, and the documented impact is confidentiality loss only. Treat this as a reconnaissance and information-disclosure risk, not proven remote code execution.
Researcher notes
Focus review on authorization and input handling around SYNO.Personal.Profile uid usage. The public description confirms information exposure but does not provide payload details, affected CPEs, or broader product impact. Avoid assuming unauthenticated access or integrity impact without vendor evidence.
Mitigation direction
- Upgrade Synology Application Service to 1.5.4-0320 or later per vendor guidance.
- Restrict access to Synology services to trusted networks and users.
- Review Synology account inventory and remove unnecessary low-privilege users.
- Monitor Synology advisory updates for any additional vendor instructions.
Validation and detection
- Inventory Synology systems and identify installed Application Service versions.
- Confirm no production system is running a version before 1.5.4-0320.
- Review which authenticated users can reach affected Synology services.
- Check available logs for unusual authenticated profile or system-information access.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
