CVE-2026-75578

Cudy TR3000 before 2.5.42 contains a command injection vulnerability in luci/model/cbi/vpn/openvpn/client.lua, which embeds the shellquote()-quoted remote host token of an uploaded OpenVPN configuration inside an already single-quoted sed program run by os.execute(), so the nested quotes terminate the outer quote. Authenticated administrators can upload an .ovpn file whose remote host token contains a semicolon to execute arbitrary commands as root.

Affected products and versions

NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.

Remediation & validation

  1. Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
  2. Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
  3. Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
  4. Validate the remediation with a version check and vulnerability rescan, then retain change evidence.

No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
