An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-6959 in the wild and no public exploit code.\n\nAffected product: Honeywell Maxpro VMS \u0026 NVR. 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-2020-6959/ (Markdown: https://insights.sbomify.com/CVE-2020-6959/index.md)","id":"CVE-2020-6959","markdown":"https://insights.sbomify.com/CVE-2020-6959/index.md","name":"CVE-2020-6959","record":{"aliases":["GHSA-3478-j759-vphx"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Video Management System","requires_auth":"none","summary":"Remote attackers can achieve code execution via unsafe deserialization in Honeywell MAXPRO VMS and NVR without authentication.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"hnmswvms_firmware","vendor":"honeywell"},{"product":"hnmswvmslt_firmware","vendor":"honeywell"},{"product":"maxpro_nvr_pe_firmware","vendor":"honeywell"},{"product":"maxpro_nvr_se_firmware","vendor":"honeywell"},{"product":"maxpro_nvr_xe_firmware","vendor":"honeywell"},{"product":"mpnvrswxx_firmware","vendor":"honeywell"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The following versions of MAXPRO VMS and NVR, MAXPRO VMS:HNMSWVMS prior to Version VMS560 Build 595 T2-Patch, HNMSWVMSLT prior to Version VMS560 Build 595 T2-Patch, MAXPRO NVR: MAXPRO NVR XE prior to Version NVR 5.6 Build 595 T2-Patch, MAXPRO NVR SE prior to Version NVR 5.6 Build 595 T2-Patch, MAXPRO NVR PE prior to Version NVR 5.6 Build 595 T2-Patch, and MPNVRSWXX prior to Version NVR 5.6 Build 595 T2-Patch are vulnerable to an unsafe deserialization of untrusted data.
