CVE-2021-47849: Mini Mouse 9.3.0 - Local File inclusion / Path Traversal

Mini Mouse 9.3.0 contains a path traversal vulnerability that allows attackers to access sensitive system directories through the device information endpoint. Attackers can retrieve file lists from system directories like /usr, /etc, and /var by manipulating file path parameters in API requests.

Security readout for executives and security teams

Plain-English summary

Mini Mouse 9.3.0 has a path traversal flaw that can let an unauthenticated network attacker view file listings from sensitive system directories. This can expose system structure and configuration clues. Public exploit information exists, but the provided sources do not show active exploitation or a named vendor patch.

Executive priority

Treat as a high-priority exposure review, especially in environments allowing personal remote-control utilities. Prioritize finding and removing or isolating version 9.3.0 because exploitation requires no credentials or user interaction, and public exploit information exists.

Technical view

CVE-2021-47849 is a CWE-22 path traversal issue in Yodinfo Mini Mouse 9.3.0. Manipulated file path parameters in the device information endpoint can retrieve directory listings such as /usr, /etc, and /var. The CVSS 4.0 score is 8.7, with network access, low complexity, no privileges, and no user interaction required.

Likely exposure

Organizations are exposed if Mini Mouse 9.3.0 is installed and its vulnerable device information endpoint is reachable by untrusted networks. Exposure is higher where the service is reachable over corporate Wi-Fi, guest networks, VPN, or the internet.

Exploitation context

A public ExploitDB reference is listed, indicating exploit details are publicly available. The source bundle marks CISA KEV as false, and no cited source states active exploitation in the wild.

Researcher notes

The available record supports directory listing exposure through path traversal, not confirmed file content disclosure or code execution. Patch status is not provided in the source bundle. Avoid assuming broader impact beyond Mini Mouse 9.3.0 unless verified through vendor documentation or controlled testing.

Mitigation direction

  • Identify any Mini Mouse 9.3.0 installations in managed and user-owned environments.
  • Check Yodinfo/App Store guidance for updated versions or vendor remediation.
  • Remove or disable Mini Mouse 9.3.0 where it is not business-critical.
  • Restrict access to the Mini Mouse service to trusted local networks only.
  • Block exposure from guest Wi-Fi, VPN, and internet-facing paths where possible.

Validation and detection

  • Confirm whether Mini Mouse 9.3.0 is installed on endpoints.
  • Determine whether the device information endpoint is reachable from untrusted networks.
  • Review access logs for path traversal indicators in file path parameters.
  • Verify any installed update against vendor or App Store release information.
  • Document compensating controls if no vendor fix is available.
