It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-66620 in the wild and no public exploit code.\n\nAffected product: Columbia Weather Systems MicroServer. 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-2025-66620/ (Markdown: https://insights.sbomify.com/CVE-2025-66620/index.md)","id":"CVE-2025-66620","markdown":"https://insights.sbomify.com/CVE-2025-66620/index.md","name":"CVE-2025-66620","record":{"aliases":["GHSA-mh3m-m8m5-x43f"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["code_execution","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Weather monitoring server","requires_auth":"low_privilege","summary":"An attacker with admin access can exploit an unused webshell to gain shell access, modify data, and establish persistence on the MicroServer.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"weather_microserver_firmware","vendor":"columbiaweather"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-553","name":"Command Shell in Externally Accessible Directory"}],"description":"An unused webshell in MicroServer allows unlimited login attempts, with sudo rights on certain files and directories.
