An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-16784 in the wild and no public exploit code.\n\nAffected product: Dedecms Dedecms. 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-2018-16784/ (Markdown: https://insights.sbomify.com/CVE-2018-16784/index.md)","id":"CVE-2018-16784","markdown":"https://insights.sbomify.com/CVE-2018-16784/index.md","name":"CVE-2018-16784","record":{"aliases":["GHSA-mr9x-r224-2f2x"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"DedeCMS","requires_auth":"high_privilege","summary":"Attackers can achieve remote code execution in DedeCMS by injecting malicious XML payloads into file upload parameters.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dedecms","vendor":"dedecms"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-91","name":"XML Injection"}],"description":"DedeCMS 5.7 SP2 allows XML injection, and resultant remote code execution, via a \"\u003cfile type='file' name='../\" substring.","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":"XML external entity in n/a","id":"CVE-2018-16784","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dedecms:dedecms","products":["dedecms:dedecms"],"type":"xxe","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"XML external entity in n/a","id":"CVE-2018-16785"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-16782"},"products":["n/a"],"published":"2018-09-21","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2026-30643","kev_date_added":null,"published":"2026-04-01"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2026-30694","kev_date_added":null,"published":"2026-03-19"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-35510","kev_date_added":null,"published":"2024-05-28"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-35375","kev_date_added":null,"published":"2024-05-23"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-29661","kev_date_added":null,"published":"2024-04-22"},{"cvss_score":9.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2024-29684","kev_date_added":null,"published":"2024-03-26"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2023-40784","kev_date_added":null,"published":"2023-09-12"}],"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 achieve remote code execution in DedeCMS by injecting malicious XML payloads into file upload parameters.","url":"https://insights.sbomify.com/CVE-2018-16784/"}
