Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-27386 exists.\n\nAffected product: n/a. 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-2020-27386/ (Markdown: https://insights.sbomify.com/CVE-2020-27386/index.md)","id":"CVE-2020-27386","markdown":"https://insights.sbomify.com/CVE-2020-27386/index.md","name":"CVE-2020-27386","record":{"aliases":["GHSA-j66w-g54r-w535"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FlexDotnetCMS","requires_auth":"low_privilege","summary":"Authenticated attackers can upload malicious files and rename them to executable extensions to achieve remote code execution in FlexDotnetCMS.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"flexdotnetcms","vendor":"flexdotnetcms_project"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"An unrestricted file upload issue in FlexDotnetCMS before v1.5.9 allows an authenticated remote attacker to upload and execute arbitrary files by using the FileManager to upload malicious code (e.g., ASP code) in the form of a safe file type (e.g., a TXT file), and then using the FileEditor (in v1.5.8 and prior) or the FileManager's rename function (in v1.5.7 and prior) to rename the file to an executable extension (e.g., ASP), and finally executing the file via an HTTP GET request to /\u003cpath_to_file\u003e.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-09-28","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2020-09-28","kind":"metasploit","ref":"exploit/windows/http/flexdotnetcms_upload_exec","stars":null,"title":"FlexDotnetCMS Arbitrary ASP File Upload"}],"tier":"weaponised"},"has_fix":false,"headline":"File upload in n/a","id":"CVE-2020-27386","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"File upload in n/a","id":"CVE-2020-27387"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2020-27385"},"products":["n/a"],"published":"2020-11-12","related":[{"cvss_score":8.1,"headline":"Path traversal in n/a","id":"CVE-2020-27385","kev_date_added":null,"published":"2020-11-12"}],"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Authenticated attackers can upload malicious files and rename them to executable extensions to achieve remote code execution in FlexDotnetCMS.","url":"https://insights.sbomify.com/CVE-2020-27386/"}
