SolarView Compact, published on 24 Feb 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20661 in the wild and no public exploit code.\n\nAffected product: Contec Co., Ltd. SolarView Compact. 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-2021-20661/ (Markdown: https://insights.sbomify.com/CVE-2021-20661/index.md)","id":"CVE-2021-20661","markdown":"https://insights.sbomify.com/CVE-2021-20661/index.md","name":"CVE-2021-20661","record":{"aliases":["GHSA-jw7g-5p4f-2mpw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SolarView Compact","requires_auth":"low_privilege","summary":"Authenticated attackers can delete arbitrary files and directories on SolarView Compact servers via a directory traversal vulnerability.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"sv-cpt-mc310_firmware","vendor":"contec"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Directory traversal vulnerability in SolarView Compact SV-CPT-MC310 prior to Ver.6.5 allows authenticated attackers to delete arbitrary files and/or directories on the server via unspecified vectors.","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 SolarView Compact","id":"CVE-2021-20661","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Missing authorization in SolarView Compact","id":"CVE-2021-20662"},"packages":[],"prev":{"headline":"Cross-site scripting in SolarView Compact","id":"CVE-2021-20660"},"products":["SolarView Compact"],"published":"2021-02-24","related":[{"cvss_score":9.8,"headline":"SolarView Compact Command Injection","id":"CVE-2022-29303","kev_date_added":"2023-07-13","published":"2022-05-12"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2022-31374","kev_date_added":null,"published":"2022-06-21"},{"cvss_score":9.8,"headline":"SolarView Compact SV-CPT-MC310 prior to Ver.6.5 allows an attacker to execute arbitrary OS commands with the web server privilege via unspecified vectors.","id":"CVE-2021-20658","kev_date_added":null,"published":"2021-02-24"},{"cvss_score":8.8,"headline":"Command injection in SolarView Compact","id":"CVE-2023-27514","kev_date_added":null,"published":"2023-05-23"},{"cvss_score":8.8,"headline":"Memory corruption in SolarView Compact","id":"CVE-2023-27518","kev_date_added":null,"published":"2023-05-23"},{"cvss_score":8.8,"headline":"Command injection in SolarView Compact","id":"CVE-2023-27521","kev_date_added":null,"published":"2023-05-23"},{"cvss_score":8.8,"headline":"File upload in SolarView Compact","id":"CVE-2022-35239","kev_date_added":null,"published":"2022-08-16"}],"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":"2024-08-03","vendors":["Contec Co., Ltd."]},"summary":"Authenticated attackers can delete arbitrary files and directories on SolarView Compact servers via a directory traversal vulnerability.","url":"https://insights.sbomify.com/CVE-2021-20661/"}
