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-2021-31684 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- net.minidev:json-smart (Maven): affected from 1.3.0; fixed in 1.3.3\n- net.minidev:json-smart (Maven): affected from 1.3.0; fixed in 1.3.3\n- net.minidev:json-smart (Maven): affected from 2.4.0; fixed in 2.4.4\n- net.minidev:json-smart (Maven): affected from 2.4.0; fixed in 2.4.4\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-2021-31684/ (Markdown: https://insights.sbomify.com/CVE-2021-31684/index.md)","id":"CVE-2021-31684","markdown":"https://insights.sbomify.com/CVE-2021-31684/index.md","name":"CVE-2021-31684","record":{"aliases":["CLEANSTART-2026-FO78987","CLEANSTART-2026-GB22495","CLSA-2026-1773015250","CLSA-2026-1789372281","CLSA-2026-1789461880","DEBIAN-CVE-2021-31684","ECHO-5abf-ee02-406a","GHSA-fg2v-w576-w4v3","MINI-jmm2-mfmr-6wm3","MINI-qhh6-p4hr-x8pp","MINI-vxm4-m6hj-qvj5","MINI-w272-p543-x4cp","UBUNTU-CVE-2021-31684"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java JSON parsing library","requires_auth":"none","summary":"Attackers can cause a denial of service in applications using JSON Smart by sending crafted web requests that trigger an out-of-bounds write.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"json-smart-v1","vendor":"json-smart_project"},{"product":"json-smart-v2","vendor":"json-smart_project"},{"product":"utilities_framework","vendor":"oracle"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A vulnerability was discovered in the indexOf function of JSONParserByteArray in JSON Smart versions 1.3 and 2.4 which causes a denial of service (DOS) via a crafted web request.","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":"Out of bounds read in json-smart","id":"CVE-2021-31684","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":4,"n_references":8,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-31693"},"packages":[{"ecosystem":"Maven","fixed":["1.3.3"],"introduced":["1.3.0"],"last_affected":[],"package":"net.minidev:json-smart","purl":null,"source":"GHSA-fg2v-w576-w4v3"},{"ecosystem":"Maven","fixed":["1.3.3"],"introduced":["1.3.0"],"last_affected":[],"package":"net.minidev:json-smart","purl":"pkg:maven/net.minidev/json-smart","source":"GHSA-fg2v-w576-w4v3"},{"ecosystem":"Maven","fixed":["2.4.4"],"introduced":["2.4.0"],"last_affected":[],"package":"net.minidev:json-smart","purl":null,"source":"GHSA-fg2v-w576-w4v3"},{"ecosystem":"Maven","fixed":["2.4.4"],"introduced":["2.4.0"],"last_affected":[],"package":"net.minidev:json-smart","purl":"pkg:maven/net.minidev/json-smart","source":"GHSA-fg2v-w576-w4v3"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-31682"},"products":["n/a"],"published":"2021-06-01","related":[{"cvss_score":5.9,"headline":"Improper Check for Unusual or Exceptional Conditions in json-smart","id":"CVE-2021-27568","kev_date_added":null,"published":"2021-02-23"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in applications using JSON Smart by sending crafted web requests that trigger an out-of-bounds write.","url":"https://insights.sbomify.com/CVE-2021-31684/"}
