Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-12940 in the wild and no public exploit code.\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-2018-12940/ (Markdown: https://insights.sbomify.com/CVE-2018-12940/index.md)","id":"CVE-2018-12940","markdown":"https://insights.sbomify.com/CVE-2018-12940/index.md","name":"CVE-2018-12940","record":{"aliases":["GHSA-8gcf-w7r4-3qhx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SeedDMS document management","requires_auth":"low_privilege","summary":"Authenticated attackers can upload malicious PHP files to execute arbitrary code on the server via unrestricted file upload in SeedDMS.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"seeddms","vendor":"seeddms"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Unrestricted file upload vulnerability in \"op/op.UploadChunks.php\" in SeedDMS (formerly LetoDMS and MyDMS) before 5.1.8 allows remote attackers to execute arbitrary code by uploading a file with an executable extension specified by the \"qqfile\" parameter.
