An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-18917 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-2020-18917/ (Markdown: https://insights.sbomify.com/CVE-2020-18917/index.md)","id":"CVE-2020-18917","markdown":"https://insights.sbomify.com/CVE-2020-18917/index.md","name":"CVE-2020-18917","record":{"aliases":["GHSA-rmp8-hcf7-f7mf"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"DedeCMS","requires_auth":"none","summary":"Remote attackers can execute arbitrary PHP code in DedeCMS via the typename parameter in the search component.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dedecms","vendor":"dedecms"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"The plus/search.php component in DedeCMS 5.7 SP2 allows remote attackers to execute arbitrary PHP code via the typename parameter because the contents of typename.inc are under an attacker's control.","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":"Code injection in n/a","id":"CVE-2020-18917","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dedecms:dedecms","products":["dedecms:dedecms"],"type":"code_injection","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-18964"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2020-18913"},"products":["n/a"],"published":"2021-08-24","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":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary PHP code in DedeCMS via the typename parameter in the search component.","url":"https://insights.sbomify.com/CVE-2020-18917/"}
