Security readout for executives and security teams
Plain-English summary
Synology DSM had a path traversal flaw in its webapi component. A remote user who is already authenticated with high privileges could delete files outside the intended directory, potentially disrupting NAS services or data availability.
Executive priority
Prioritize remediation for internet-reachable or shared administrative DSM environments. The flaw is not known exploited from the supplied sources, but arbitrary file deletion can create business disruption if a privileged account is compromised or misused.
Technical view
CVE-2022-27610 is CWE-22 in Synology DiskStation Manager before 6.2.3-25423. The record says remote authenticated users can delete arbitrary files through unspecified webapi vectors. CVSS 3.1 is 6.5 with high integrity and availability impact, high privileges required, and no user interaction.
Likely exposure
Exposure is likely limited to Synology DSM systems older than 6.2.3-25423 where privileged authenticated users can reach DSM webapi, especially management interfaces exposed beyond trusted networks.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not marked KEV. Public details are limited; the specific vectors are unspecified, so risk assessment should focus on version, authentication controls, and management exposure.
Researcher notes
The record lacks exploit detail and names only unspecified webapi vectors. Avoid exploit reproduction as a validation method; use authenticated inventory, version checks, exposure mapping, account review, and log analysis. Affected scope is DSM before 6.2.3-25423.
Mitigation direction
- Upgrade affected DSM systems to 6.2.3-25423 or later per Synology guidance.
- Restrict DSM management and webapi access to trusted networks or VPN paths.
- Remove unnecessary privileged DSM accounts and enforce strong authentication controls.
- Maintain tested backups for critical NAS data and configuration.
- Check Synology advisory updates before relying on compensating controls.
Validation and detection
- Confirm each Synology DSM host is running 6.2.3-25423 or later.
- Inventory DSM systems reachable from the internet or untrusted networks.
- Review DSM logs for unusual authenticated file deletion or webapi activity.
- Verify privileged account lists and recent authentication history.
- Confirm backups can restore critical data and configuration.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
