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-2021-31635 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.jfinal:jfinal (Maven): affected all versions up to 4.9.08; no fix listed\n- com.jfinal:jfinal (Maven): affected all versions up to 4.9.08; 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-2021-31635/ (Markdown: https://insights.sbomify.com/CVE-2021-31635/index.md)","id":"CVE-2021-31635","markdown":"https://insights.sbomify.com/CVE-2021-31635/index.md","name":"CVE-2021-31635","record":{"aliases":["GHSA-cgmm-c2m9-ff7r"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via Server-Side Template Injection in the jFinal Java web framework.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jfinal","vendor":"jfinal"}],"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-94","name":"Improper Control of Generation of Code"}],"description":"Server-Side Template Injection (SSTI) vulnerability in jFinal v.4.9.08 allows a remote attacker to execute arbitrary code via the template function.","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":"jFinal Server-Side Template Injection vulnerability","id":"CVE-2021-31635","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":"Code injection in n/a","id":"CVE-2021-31637"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["4.9.08"],"package":"com.jfinal:jfinal","purl":null,"source":"GHSA-cgmm-c2m9-ff7r"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["4.9.08"],"package":"com.jfinal:jfinal","purl":"pkg:maven/com.jfinal/jfinal","source":"GHSA-cgmm-c2m9-ff7r"}],"prev":{"headline":"SQL injection in n/a","id":"CVE-2021-31632"},"products":["n/a"],"published":"2023-06-26","related":[{"cvss_score":9.8,"headline":"JFinal Java Deserialization Vulnerability","id":"CVE-2021-31649","kev_date_added":null,"published":"2021-06-24"},{"cvss_score":7.5,"headline":"JFinal file validation vulnerability","id":"CVE-2019-17352","kev_date_added":null,"published":"2019-10-08"},{"cvss_score":6.1,"headline":"Cross-site scripting in jfinal","id":"CVE-2021-33348","kev_date_added":null,"published":"2021-06-24"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-12-05","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via Server-Side Template Injection in the jFinal Java web framework.","url":"https://insights.sbomify.com/CVE-2021-31635/"}
