It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-8144 and fix it if it is affected.\n\nWhat it is: CVE-2020-8144 is a high-severity path traversal vulnerability in UniFi Video Controller (for Windows 7/8/10 x64), published on 1 Apr 2020. 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-2020-8144 in the wild and no public exploit code.\n\nAffected product: UniFi Video Controller (for Windows 7/8/10 x64). 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-2020-8144/ (Markdown: https://insights.sbomify.com/CVE-2020-8144/index.md)","id":"CVE-2020-8144","markdown":"https://insights.sbomify.com/CVE-2020-8144/index.md","name":"CVE-2020-8144","record":{"aliases":["GHSA-8vc5-gg9h-3rv8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UniFi Video Controller","requires_auth":"high_privilege","summary":"Attackers can manipulate firmware update paths to write files outside the intended directory, potentially leading to arbitrary file write or code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"unifi_video","vendor":"ui"}],"cvss":{"score":8.4,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"The UniFi Video Server v3.9.3 and prior (for Windows 7/8/10 x64) web interface Firmware Update functionality, under certain circumstances, does not validate firmware download destinations to ensure they are within the intended destination directory tree.
