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-2020-5797 in the wild and no public exploit code.\n\nAffected product: TP-Link Archer C9 A1. 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-2020-5797/ (Markdown: https://insights.sbomify.com/CVE-2020-5797/index.md)","id":"CVE-2020-5797","markdown":"https://insights.sbomify.com/CVE-2020-5797/index.md","name":"CVE-2020-5797","record":{"aliases":["GHSA-6qx3-hcm8-xh2m"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TP-Link Archer C9 router","requires_auth":"none","summary":"An attacker with physical access can use a crafted USB drive to read sensitive files and modify limited files on the router via symlink following.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"archer_c9_firmware","vendor":"tp-link"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"UNIX Symbolic Link (Symlink) Following in TP-Link Archer C9(US)_V1_180125 firmware allows an unauthenticated actor, with physical access and network access, to read sensitive files and write to a limited set of files after plugging a crafted USB drive into the router.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Path traversal in TP-Link Archer C9 A1","id":"CVE-2020-5797","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Druva inSync macOS Client Installers for v6.8.0 and prior","id":"CVE-2020-5798"},"packages":[],"prev":{"headline":"Privilege escalation in Nagios XI","id":"CVE-2020-5796"},"products":["TP-Link Archer C9 A1"],"published":"2020-11-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"An attacker with physical access can use a crafted USB drive to read sensitive files and modify limited files on the router via symlink following.","url":"https://insights.sbomify.com/CVE-2020-5797/"}
