An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-42112 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- limesurvey/limesurvey (Packagist): affected all versions; fixed in 3.27.19\n- limesurvey/limesurvey (Packagist): affected all versions; fixed in 3.27.19\n- limesurvey (Bitnami): affected from 3.0.0; fixed in 3.27.19\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-2021-42112/ (Markdown: https://insights.sbomify.com/CVE-2021-42112/index.md)","id":"CVE-2021-42112","markdown":"https://insights.sbomify.com/CVE-2021-42112/index.md","name":"CVE-2021-42112","record":{"aliases":["BIT-limesurvey-2021-42112","GHSA-h9ph-jcgh-gf69"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"LimeSurvey survey tool","requires_auth":"none","summary":"Cross-site scripting in LimeSurvey's file upload feature allows attackers to execute arbitrary scripts in victim browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"limesurvey","vendor":"limesurvey"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The \"File upload question\" functionality in LimeSurvey 3.x-LTS through 3.27.18 allows XSS in assets/scripts/modaldialog.js and assets/scripts/uploader.js.","ecosystems":["Bitnami","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":"Cross-site Scripting in Limesurvey","id":"CVE-2021-42112","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"limesurvey:limesurvey","products":["limesurvey:limesurvey"],"type":"xss","year":"2021"},"n_packages":3,"n_references":3,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2021-42113"},"packages":[{"ecosystem":"Bitnami","fixed":["3.27.19"],"introduced":["3.0.0"],"last_affected":[],"package":"limesurvey","purl":"pkg:bitnami/limesurvey","source":"BIT-limesurvey-2021-42112"},{"ecosystem":"Packagist","fixed":["3.27.19"],"introduced":["0"],"last_affected":[],"package":"limesurvey/limesurvey","purl":null,"source":"GHSA-h9ph-jcgh-gf69"},{"ecosystem":"Packagist","fixed":["3.27.19"],"introduced":["0"],"last_affected":[],"package":"limesurvey/limesurvey","purl":"pkg:composer/limesurvey/limesurvey","source":"GHSA-h9ph-jcgh-gf69"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-42111"},"products":["n/a"],"published":"2021-10-08","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2025-56422","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2022-48008","kev_date_added":null,"published":"2023-01-27"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2019-25019","kev_date_added":null,"published":"2021-02-14"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2020-11455","kev_date_added":null,"published":"2020-04-01"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2019-16184","kev_date_added":null,"published":"2019-09-09"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2019-9960","kev_date_added":null,"published":"2019-03-24"},{"cvss_score":9.8,"headline":"TCPDF vulnerable to attackers triggering deserialization of arbitrary data","id":"CVE-2018-17057","kev_date_added":null,"published":"2018-09-14"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"Cross-site scripting in LimeSurvey's file upload feature allows attackers to execute arbitrary scripts in victim browsers.","url":"https://insights.sbomify.com/CVE-2021-42112/"}
