Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8858 in the wild and no public exploit code.\n\nAffected product: Moxa MGate 5105-MB-EIP. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-8858/ (Markdown: https://insights.sbomify.com/CVE-2020-8858/index.md)","id":"CVE-2020-8858","markdown":"https://insights.sbomify.com/CVE-2020-8858/index.md","name":"CVE-2020-8858","record":{"aliases":["GHSA-8qrp-hmq9-5pcx"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial gateway","requires_auth":"low_privilege","summary":"Remote authenticated attackers can execute arbitrary code as root via improper validation of the DestIP parameter in Moxa MGate firmware.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"mgate_5105-mb-eip-t_firmware","vendor":"moxa"},{"product":"mgate_5105-mb-eip_firmware","vendor":"moxa"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"This vulnerability allows remote attackers to execute arbitrary code on affected installations of Moxa MGate 5105-MB-EIP firmware version 4.1.
