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-2023-4220/ (Markdown: https://insights.sbomify.com/CVE-2023-4220/index.md)","id":"CVE-2023-4220","markdown":"https://insights.sbomify.com/CVE-2023-4220/index.md","name":"CVE-2023-4220","record":{"aliases":["GHSA-9wc2-3gq5-2f4c"],"analysis":null,"analysis_generated_by":null,"assigner":"STAR_Labs","cpe":[{"product":"chamilo_lms","vendor":"chamilo"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Unrestricted file upload in big file upload functionality in `/main/inc/lib/javascript/bigupload/inc/bigUpload.php` in Chamilo LMS \u003c= v1.11.24 allows unauthenticated attackers to perform stored cross-site scripting attacks and obtain remote code execution via uploading of web shell.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2023-11-28","github_poc":26,"max_poc_stars":5,"metasploit":1,"nuclei":1,"refs":[{"date":"2024-07-07T23:23:17Z","kind":"github_poc","ref":"https://github.com/Rai2en/CVE-2023-4220-Chamilo-LMS","stars":5,"title":"This is a script written in Python that allows the exploitation of the Chamilo's LMS software security flaw described in CVE-2023-4220"},{"date":"2024-07-08T09:48:38Z","kind":"github_poc","ref":"https://github.com/Ziad-Sakr/Chamilo-CVE-2023-4220-Exploit","stars":4,"title":"This is an Exploit for Unrestricted file upload in big file upload functionality in Chamilo-LMS for this location \"/main/inc/lib/javascript/bigupload/inc/bigUpload.php\" in Chamilo LMS \u003c= v1.11.24, and Attackers can obtain remote code execution via uploading of web shell."},{"date":"2024-08-24T15:25:28Z","kind":"github_poc","ref":"https://github.com/thefizzyfish/CVE-2023-4220_Chamilo_RCE","stars":2,"title":"Python exploit for Chamilo Unrestricted File Upload Vuln -
