Security readout for executives and security teams
Plain-English summary
Synology DSM versions before 6.2-23739 contain a command injection issue in EZ-Internet. A remote user who is already authenticated with high privileges could run arbitrary system commands, potentially compromising confidentiality, integrity, and availability of the NAS.
Executive priority
Prioritize remediation for internet-reachable or broadly accessible DSM administration surfaces. This requires high privileges, so urgency is highest where admin credentials may be shared, weak, reused, or exposed.
Technical view
CVE-2017-12075 is CWE-77 command injection in DSM EZ-Internet. The username parameter is identified as the input vector. CVSS 3.0 is 7.2, with network access, low complexity, high privileges required, no user interaction, and high CIA impact.
Likely exposure
Exposure is limited to Synology DiskStation Manager installations before 6.2-23739 where an attacker can authenticate remotely with high privileges and reach EZ-Internet functionality.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. The vulnerability is still serious because a privileged remote account could be used to execute arbitrary commands on DSM.
Researcher notes
The source bundle names DSM before 6.2-23739 and EZ-Internet username parameter but does not provide deeper exploit mechanics, affected CPEs, or observed exploitation. Avoid assuming unauthenticated exposure.
Mitigation direction
- Upgrade Synology DSM to 6.2-23739 or later, per the affected-version statement.
- Review Synology advisory Synology_SA_18_24 for current vendor guidance.
- Restrict DSM administrative access to trusted users and management networks.
- Audit privileged DSM accounts and remove unnecessary access.
Validation and detection
- Inventory Synology DSM systems and record installed DSM versions.
- Flag any DSM instance running a version before 6.2-23739.
- Confirm whether EZ-Internet is present or used on affected systems.
- Review privileged account activity around DSM administration.
- Verify remediation by confirming DSM is at or above 6.2-23739.

Improper Neutralization of Special Elements used in a Command ('Command Injection')
Improper Neutralization of Special Elements used in a Command ('Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
