CVE-2021-47847: Disk Sorter Server 13.6.12 - 'Disk Sorter Server' Unquoted Service Path

Disk Sorter Server 13.6.12 contains an unquoted service path vulnerability in its binary path configuration that allows local attackers to potentially execute arbitrary code. Attackers can exploit the unquoted path in 'C:\Program Files\Disk Sorter Server\bin\disksrs.exe' to inject malicious executables and escalate privileges.

Security readout for executives and security teams

Plain-English summary

Disk Sorter Server 13.6.12 can be misconfigured with an unquoted Windows service path. A local user with low privileges may be able to place a malicious executable in a searched path and have it run with the service’s privileges, creating a privilege-escalation risk on affected servers.

Executive priority

Treat as a high-priority hardening issue for affected servers, especially where many users have local access. It is less urgent than an internet-facing remote exploit, but it can turn a limited compromise into full server control.

Technical view

CVE-2021-47847 is a CWE-428 unquoted service path issue in Disk Sorter Server 13.6.12. The reported service binary path is C:\Program Files\Disk Sorter Server\bin\disksrs.exe. Because the path contains spaces and is unquoted, Windows path parsing can allow local code execution under elevated service context if file placement conditions are met.

Likely exposure

Exposure is limited to systems running Disk Sorter Server 13.6.12 on Windows. The attack requires local access and low privileges, so risk is highest on shared servers, jump hosts, or systems where untrusted users can write to relevant directories.

Exploitation context

ExploitDB and VulnCheck list the issue, but the provided sources do not show CISA KEV listing or confirmed active exploitation. This is not remotely exploitable by itself; it is a local privilege-escalation condition after an attacker already has access.

Researcher notes

The provided sources identify version 13.6.12 and the unquoted path condition. Patch availability is not stated in the bundle. Avoid assuming broader affected versions. Validate service configuration and filesystem permissions before declaring exposure.

Mitigation direction

  • Identify all installations of Disk Sorter Server 13.6.12.
  • Check the vendor site and advisory sources for fixed versions or official guidance.
  • Restrict local interactive access to affected servers where possible.
  • Review write permissions on parent directories in the service path.
  • If vendor-supported, correct the service path so it is safely quoted.

Validation and detection

  • Confirm the installed Disk Sorter Server version on Windows hosts.
  • Inspect the Disk Sorter Server service binary path configuration.
  • Verify whether the service path contains spaces and lacks quotes.
  • Check whether low-privileged users can write to searched path locations.
  • Document compensating controls if no vendor fix is available.
