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-2021-46063 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- net.mingsoft:ms-mcms (Maven): affected all versions up to 5.2.5; no fix listed\n- net.mingsoft:ms-mcms (Maven): affected all versions up to 5.2.5; no fix listed\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-2021-46063/ (Markdown: https://insights.sbomify.com/CVE-2021-46063/index.md)","id":"CVE-2021-46063","markdown":"https://insights.sbomify.com/CVE-2021-46063/index.md","name":"CVE-2021-46063","record":{"aliases":["GHSA-gc79-gh4f-9g6w"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MCMS web application","requires_auth":"none","summary":"An attacker can execute arbitrary code via Server Side Template Injection in the MCMS Template Management module.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mcms","vendor":"mingsoft"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"MCMS v5.2.5 was discovered to contain a Server Side Template Injection (SSTI) vulnerability via the Template Management module.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Server Side Template Injection in MCMS","id":"CVE-2021-46063","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-46064"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["5.2.5"],"package":"net.mingsoft:ms-mcms","purl":null,"source":"GHSA-gc79-gh4f-9g6w"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["5.2.5"],"package":"net.mingsoft:ms-mcms","purl":"pkg:maven/net.mingsoft/ms-mcms","source":"GHSA-gc79-gh4f-9g6w"}],"prev":{"headline":"MCMS Arbitrary File Deletion vulnerability","id":"CVE-2021-46062"},"products":["n/a"],"published":"2022-02-18","related":[{"cvss_score":9.8,"headline":"MCMS vulnerable SQL injection via the content_title parameter","id":"CVE-2025-56316","kev_date_added":null,"published":"2025-10-17"},{"cvss_score":9.8,"headline":"MCMS allows arbitrary file uploads in the ueditor component","id":"CVE-2025-29287","kev_date_added":null,"published":"2025-04-21"},{"cvss_score":9.8,"headline":"Mingsoft MCMS SQL injection","id":"CVE-2023-50578","kev_date_added":null,"published":"2023-12-30"},{"cvss_score":9.8,"headline":"Ming-Soft MCMS vulnerable to SQL injection","id":"CVE-2020-20913","kev_date_added":null,"published":"2023-04-04"},{"cvss_score":9.8,"headline":"Mingsoft MCMS SQL injection vulnerability in /mdiy/page/verify URI via fieldName parameter","id":"CVE-2022-36272","kev_date_added":null,"published":"2022-08-16"},{"cvss_score":9.8,"headline":"Mingsoft MCMS SQL injection vulnerability in /mdiy/model/delete URI via models List","id":"CVE-2022-36599","kev_date_added":null,"published":"2022-08-16"},{"cvss_score":9.8,"headline":"Unrestricted Upload of File with Dangerous Type in MCMS","id":"CVE-2022-31943","kev_date_added":null,"published":"2022-07-01"}],"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":"An attacker can execute arbitrary code via Server Side Template Injection in the MCMS Template Management module.","url":"https://insights.sbomify.com/CVE-2021-46063/"}
