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-2023-1728 in the wild and no public exploit code.\n\nAffected product: Fernus Informatics LMS. 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-2023-1728/ (Markdown: https://insights.sbomify.com/CVE-2023-1728/index.md)","id":"CVE-2023-1728","markdown":"https://insights.sbomify.com/CVE-2023-1728/index.md","name":"CVE-2023-1728","record":{"aliases":["GHSA-7c26-wxq9-97c9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Fernus LMS","requires_auth":"none","summary":"Attackers can upload malicious files to Fernus LMS to execute arbitrary OS commands or inject server-side includes.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TR-CERT","cpe":[{"product":"learning_management_systems","vendor":"fernus"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Unrestricted Upload of File with Dangerous Type vulnerability in Fernus Informatics LMS allows OS Command Injection, Server Side Include (SSI) Injection.\n\nThis issue affects LMS: before 23.04.03.","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":"Unrestricted Upload of File with Dangerous Type in Fernus LMS","id":"CVE-2023-1728","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in LibRaw","id":"CVE-2023-1729"},"packages":[],"prev":{"headline":"XSS in Proliz OBS","id":"CVE-2023-1726"},"products":["LMS"],"published":"2023-04-04","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-22","vendors":["Fernus Informatics"]},"summary":"Attackers can upload malicious files to Fernus LMS to execute arbitrary OS commands or inject server-side includes.","url":"https://insights.sbomify.com/CVE-2023-1728/"}
