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-2021-36440 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- showdoc/showdoc (Packagist): affected all versions; fixed in 2.9.6\n- showdoc/showdoc (Packagist): affected all versions; fixed in 2.9.6\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-2021-36440/ (Markdown: https://insights.sbomify.com/CVE-2021-36440/index.md)","id":"CVE-2021-36440","markdown":"https://insights.sbomify.com/CVE-2021-36440/index.md","name":"CVE-2021-36440","record":{"aliases":["GHSA-c442-3278-rhrg"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ShowDoc documentation tool","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by uploading malicious files via the file_url parameter in ShowDoc.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"showdoc","vendor":"showdoc"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Unrestricted File Upload in ShowDoc v2.9.5 allows remote attackers to execute arbitrary code via the 'file_url' parameter in the component AdminUpdateController.class.php'.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Unrestricted File Upload in ShowDoc v2.9.5","id":"CVE-2021-36440","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"file_upload","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2021-36443"},"packages":[{"ecosystem":"Packagist","fixed":["2.9.6"],"introduced":["0"],"last_affected":[],"package":"showdoc/showdoc","purl":null,"source":"GHSA-c442-3278-rhrg"},{"ecosystem":"Packagist","fixed":["2.9.6"],"introduced":["0"],"last_affected":[],"package":"showdoc/showdoc","purl":"pkg:composer/showdoc/showdoc","source":"GHSA-c442-3278-rhrg"}],"prev":{"headline":"SQL injection in n/a","id":"CVE-2021-36438"},"products":["n/a"],"published":"2021-09-08","related":[{"cvss_score":9.8,"headline":"Showdoc File Upload Vulnerability","id":"CVE-2021-41745","kev_date_added":null,"published":"2021-10-22"},{"cvss_score":9.4,"headline":"Stored XSS due to Unrestricted File Upload in star7th/showdoc","id":"CVE-2022-0942","kev_date_added":null,"published":"2022-03-15"},{"cvss_score":9.1,"headline":"There is a Unrestricted Upload of File vulnerability in ShowDoc v2.10.3 in star7th/showdoc","id":"CVE-2022-1034","kev_date_added":null,"published":"2022-03-22"},{"cvss_score":9,"headline":"Stored XSS viva axd and cshtml file upload in star7th/showdoc in star7th/showdoc","id":"CVE-2022-0945","kev_date_added":null,"published":"2022-03-15"},{"cvss_score":9,"headline":"Stored XSS viva .ofd file upload in star7th/showdoc","id":"CVE-2022-0965","kev_date_added":null,"published":"2022-03-15"},{"cvss_score":9,"headline":"Stored XSS viva cshtm file upload in star7th/showdoc","id":"CVE-2022-0946","kev_date_added":null,"published":"2022-03-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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 code by uploading malicious files via the file_url parameter in ShowDoc.","url":"https://insights.sbomify.com/CVE-2021-36440/"}
