Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-23710 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- limesurvey (Bitnami): affected from 4.2.5; fixed in 4.2.6\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-2020-23710/ (Markdown: https://insights.sbomify.com/CVE-2020-23710/index.md)","id":"CVE-2020-23710","markdown":"https://insights.sbomify.com/CVE-2020-23710/index.md","name":"CVE-2020-23710","record":{"aliases":["BIT-limesurvey-2020-23710","GHSA-h4f9-mmrc-885h"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"LimeSurvey","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts via the Notifications \u0026 data feature in LimeSurvey, potentially compromising user sessions or data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"limesurvey","vendor":"limesurvey"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Cross Site Scripting (XSS) vulneraiblity in LimeSurvey 4.2.5 on textbox via the Notifications \u0026 data feature.","ecosystems":["Bitnami"],"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 n/a","id":"CVE-2020-23710","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"limesurvey:limesurvey","products":["limesurvey:limesurvey"],"type":"xss","year":"2020"},"n_packages":1,"n_references":1,"next":{"headline":"SQL injection in n/a","id":"CVE-2020-23711"},"packages":[{"ecosystem":"Bitnami","fixed":["4.2.6"],"introduced":["4.2.5"],"last_affected":[],"package":"limesurvey","purl":"pkg:bitnami/limesurvey","source":"BIT-limesurvey-2020-23710"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-23707"},"products":["n/a"],"published":"2021-06-28","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":"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":"Attackers can inject malicious scripts via the Notifications \u0026 data feature in LimeSurvey, potentially compromising user sessions or data.","url":"https://insights.sbomify.com/CVE-2020-23710/"}
