It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-22140 exists.\n\nAffected product: TCL LinkHub Mesh Wifi. 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-2022-22140/ (Markdown: https://insights.sbomify.com/CVE-2022-22140/index.md)","id":"CVE-2022-22140","markdown":"https://insights.sbomify.com/CVE-2022-22140/index.md","name":"CVE-2022-22140","record":{"aliases":["GHSA-pm52-5843-p9xc"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TCL LinkHub Mesh Wi-Fi","requires_auth":"none","summary":"An attacker can execute arbitrary commands on TCL LinkHub Mesh Wi-Fi devices by sending a specially crafted network packet to the confsrv service.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"linkhub_mesh_wifi_ac1200","vendor":"tcl"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:C/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":"An os command injection vulnerability exists in the confsrv ucloud_add_node functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14.
