Security readout for executives and security teams
Plain-English summary
This flaw affects Synology DiskStation Manager before 6.1.1-15088. An authenticated remote user could abuse port-forwarding rule handling to consume memory and cause a denial of service, potentially making the NAS unavailable until recovered.
Executive priority
Treat as a maintenance-priority availability issue. It is not flagged as actively exploited in the provided sources, but vulnerable NAS devices can support important business data and services, so confirm upgrade status during the next patch cycle.
Technical view
CVE-2017-12076 is an uncontrolled resource consumption issue in SYNO.Core.PortForwarding.Rules in Synology DSM before 6.1.1-15088. The stated impact is memory exhaustion leading to denial of service by a remote authenticated attacker. No CVSS, CWE, or detailed affected CPEs are provided in the bundle.
Likely exposure
Exposure is most likely where Synology DSM instances before 6.1.1-15088 allow remote authenticated access to port-forwarding rule functionality. The bundle does not identify specific models, packages, or CPEs.
Exploitation context
The source bundle does not report public exploitation, and CISA KEV status is false. The attacker is described as remote but authenticated, which reduces likelihood versus unauthenticated flaws while still creating operational risk for shared or externally reachable DSM environments.
Researcher notes
Evidence is limited to CVE data and Synology’s advisory reference. The bundle lacks CVSS, CWE, model-level affected data, exploit details, and operational indicators. Avoid assuming broader product impact beyond DSM before 6.1.1-15088.
Mitigation direction
- Upgrade affected DSM systems to 6.1.1-15088 or later per Synology guidance.
- Review Synology advisory SA-17:48 for supported fixed versions and platform details.
- Restrict DSM administrative access to trusted users only.
- Reduce remote management exposure until affected systems are confirmed updated.
Validation and detection
- Inventory Synology DSM systems and record exact DSM versions.
- Flag DSM versions earlier than 6.1.1-15088 for remediation review.
- Confirm whether remote authenticated users can manage port-forwarding rules.
- Check monitoring for unexplained DSM memory exhaustion or availability incidents.
