Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-61939 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-2025-61939/ (Markdown: https://insights.sbomify.com/CVE-2025-61939/index.md)","id":"CVE-2025-61939","markdown":"https://insights.sbomify.com/CVE-2025-61939/index.md","name":"CVE-2025-61939","record":{"aliases":["GHSA-868w-86hc-x374"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Weather monitoring server","requires_auth":"low_privilege","summary":"An attacker with local network access and DNS control can hijack a reverse SSH connection to intercept data or bypass security controls.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"weather_microserver_firmware","vendor":"columbiaweather"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/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-923","name":"Improper Restriction of Communication Channel to Intended Endpoints"}],"description":"An unused function in MicroServer can start a reverse SSH connection to a vendor registered domain, without mutual authentication.
