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-2018-16731 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-2018-16731/ (Markdown: https://insights.sbomify.com/CVE-2018-16731/index.md)","id":"CVE-2018-16731","markdown":"https://insights.sbomify.com/CVE-2018-16731/index.md","name":"CVE-2018-16731","record":{"aliases":["GHSA-m2qv-8rfq-vrg4"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CScms","requires_auth":"none","summary":"Attackers can upload malicious PHP files by manipulating file type lists and JSON data, leading to remote code execution on CScms installations.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cscms","vendor":"chshcms"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/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":"CScms 4.1 allows arbitrary file upload by (for example) adding the php extension to the default filetype list (gif, jpg, png), and then providing a .php pathname within fileurl JSON data.","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":"File upload in n/a","id":"CVE-2018-16731","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2018-16732"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-16730"},"products":["n/a"],"published":"2018-09-08","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2020-28102","kev_date_added":null,"published":"2022-01-11"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2020-28103","kev_date_added":null,"published":"2022-01-11"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-21238","kev_date_added":null,"published":"2021-12-27"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2020-22848","kev_date_added":null,"published":"2021-08-30"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2018-17126","kev_date_added":null,"published":"2018-09-17"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2022-28552","kev_date_added":null,"published":"2022-05-04"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can upload malicious PHP files by manipulating file type lists and JSON data, leading to remote code execution on CScms installations.","url":"https://insights.sbomify.com/CVE-2018-16731/"}
