Security readout for executives and security teams
Plain-English summary
Synology Media Server versions before 1.8.1-2876 could disclose sensitive information to a remote attacker without authentication. The public record does not describe what information is exposed or the exact vector. Treat this as a moderate confidentiality issue for NAS devices running the package, especially where the service is reachable from untrusted networks.
Executive priority
Prioritize remediation during normal vulnerability maintenance unless the service is internet-exposed or handles sensitive media or user data. Internet-reachable instances should be updated promptly because exploitation requires no authentication.
Technical view
CVE-2022-27614 is a CWE-200 information exposure issue in the Synology Media Server web server. CVSS 3.1 is 5.3: network reachable, low complexity, no privileges, no user interaction, low confidentiality impact, and no integrity or availability impact. Affected versions are stated only as before 1.8.1-2876.
Likely exposure
Exposure is limited to Synology systems running Media Server before 1.8.1-2876. Risk is higher if the Media Server web service is reachable from the internet, guest networks, or other untrusted segments.
Exploitation context
The provided sources do not report active exploitation, and this CVE is not listed as KEV in the source bundle. Attack vectors are unspecified, so validation should focus on version and exposure rather than probing behavior.
Researcher notes
Public details are sparse: no CPEs, no named affected subversions beyond before 1.8.1-2876, and no disclosed vector. Avoid assuming exploitability beyond the CVSS attributes and vendor advisory. Asset-version validation is the strongest available assessment path.
Mitigation direction
- Update Synology Media Server to version 1.8.1-2876 or later.
- Review Synology advisory Synology_SA_20_24 for current vendor guidance.
- Restrict Media Server access to trusted networks where possible.
- Remove or disable Media Server if it is not operationally required.
Validation and detection
- Inventory Synology NAS devices with Media Server installed.
- Confirm each Media Server package version is 1.8.1-2876 or later.
- Check whether Media Server is reachable from untrusted networks.
- Document remaining exposed instances and assign update ownership.

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.
