An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-23267 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.craftercms:crafter-studio (Maven): affected from 3.1.0; fixed in 3.1.18\n- org.craftercms:crafter-studio (Maven): affected from 3.1.0; fixed in 3.1.18\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-2021-23267/ (Markdown: https://insights.sbomify.com/CVE-2021-23267/index.md)","id":"CVE-2021-23267","markdown":"https://insights.sbomify.com/CVE-2021-23267/index.md","name":"CVE-2021-23267","record":{"aliases":["GHSA-r6fx-55x3-f9x6"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Crafter CMS","requires_auth":"high_privilege","summary":"Authenticated developers can execute OS commands via FreeMarker static methods in Crafter Studio, allowing arbitrary code execution.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"crafter","cpe":[{"product":"crafter_cms","vendor":"craftercms"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-913","name":"Improper Control of Dynamically-Managed Code Resources"}],"description":"Improper Control of Dynamically-Managed Code Resources vulnerability in Crafter Studio of Crafter CMS allows authenticated developers to execute OS commands via FreeMarker static methods.","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":true,"headline":"Improper Control of Dynamically-Managed Code Resources in Crafter Studio","id":"CVE-2021-23267","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":"Denial of service in n/a","id":"CVE-2021-23270"},"packages":[{"ecosystem":"Maven","fixed":["3.1.18"],"introduced":["3.1.0"],"last_affected":[],"package":"org.craftercms:crafter-studio","purl":null,"source":"GHSA-r6fx-55x3-f9x6"},{"ecosystem":"Maven","fixed":["3.1.18"],"introduced":["3.1.0"],"last_affected":[],"package":"org.craftercms:crafter-studio","purl":"pkg:maven/org.craftercms/crafter-studio","source":"GHSA-r6fx-55x3-f9x6"}],"prev":{"headline":"Improper Output Neutralization for Logs in Crafter Studio","id":"CVE-2021-23266"},"products":["Crafter CMS"],"published":"2022-05-16","related":[{"cvss_score":9.8,"headline":"Path Traversal in Crafter CMS Crafter Studio","id":"CVE-2017-15681","kev_date_added":null,"published":"2020-11-27"},{"cvss_score":8.8,"headline":"OS Command Injection in craftercms:crafter-studio","id":"CVE-2018-19907","kev_date_added":null,"published":"2018-12-06"},{"cvss_score":8.6,"headline":"XML injection in Crafter CMS","id":"CVE-2017-15683","kev_date_added":null,"published":"2020-11-27"},{"cvss_score":8.6,"headline":"XML Injection in Crafter CMS Crafter Studio 3.0.1","id":"CVE-2017-15685","kev_date_added":null,"published":"2020-11-27"},{"cvss_score":8.1,"headline":"Exposure of Resource to Wrong Sphere in org.craftercms:crafter-search","id":"CVE-2021-23264","kev_date_added":null,"published":"2021-12-02"},{"cvss_score":7.5,"headline":"Path Traversal in Crafter CMS Crafter Studio","id":"CVE-2017-15684","kev_date_added":null,"published":"2020-11-27"}],"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":"2024-09-16","vendors":["Crafter Software"]},"summary":"Authenticated developers can execute OS commands via FreeMarker static methods in Crafter Studio, allowing arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2021-23267/"}
