An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-30943 exists.\n\nAffected packages and fixed versions:\n- moodle/moodle (Packagist): affected all versions; fixed in 4.2.0-rc2\n- moodle/moodle (Packagist): affected all versions; fixed in 4.2.0-rc2\n- moodle (Bitnami): affected from 4.1.0; fixed in 4.1.3\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-2023-30943/ (Markdown: https://insights.sbomify.com/CVE-2023-30943/index.md)","id":"CVE-2023-30943","markdown":"https://insights.sbomify.com/CVE-2023-30943/index.md","name":"CVE-2023-30943","record":{"aliases":["BIT-moodle-2023-30943","GHSA-22gj-8qj2-fj46","UBUNTU-CVE-2023-30943"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Moodle LMS","requires_auth":"none","summary":"Remote attackers can create arbitrary folders on the server via crafted HTTP requests in TinyMCE loaders, requiring patching of Moodle installations.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fedora","cpe":[{"product":"extra_packages_for_enterprise_linux","vendor":"fedoraproject"},{"product":"fedora","vendor":"fedoraproject"},{"product":"moodle","vendor":"moodle"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-610","name":"Externally Controlled Reference to a Resource in Another Sphere"},{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"The vulnerability was found Moodle which exists because the application allows a user to control path of the older to create in TinyMCE loaders.
