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-2020-21053 in the wild and no public exploit code.\n\nAffected product: Fusionpbx Fusionpbx. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-21053/ (Markdown: https://insights.sbomify.com/CVE-2020-21053/index.md)","id":"CVE-2020-21053","markdown":"https://insights.sbomify.com/CVE-2020-21053/index.md","name":"CVE-2020-21053","record":{"aliases":["GHSA-w9pj-vvhp-w8m8"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"FusionPBX","requires_auth":"none","summary":"Remote attackers can inject arbitrary scripts via the query_string parameter in FusionPBX, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fusionpbx","vendor":"fusionpbx"}],"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":"Cross Site Scriptiong (XSS) vulnerability exists in FusionPBX 4.5.7 allows remote malicious users to inject arbitrary web script or HTML via an unsanitized \"query_string\" variable in app\\devices\\device_imports.php.","ecosystems":[],"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":"Cross-site scripting in n/a","id":"CVE-2020-21053","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fusionpbx:fusionpbx","products":["fusionpbx:fusionpbx"],"type":"xss","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-21054"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-21052"},"products":["n/a"],"published":"2021-05-20","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-35153","kev_date_added":null,"published":"2022-08-18"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-28055","kev_date_added":null,"published":"2022-05-04"},{"cvss_score":8.8,"headline":"Path traversal in n/a","id":"CVE-2021-43404","kev_date_added":null,"published":"2021-11-05"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-43405","kev_date_added":null,"published":"2021-11-05"},{"cvss_score":8.8,"headline":"Other in n/a","id":"CVE-2021-43406","kev_date_added":null,"published":"2021-11-05"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2019-16964","kev_date_added":null,"published":"2019-10-21"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2019-16980","kev_date_added":null,"published":"2019-10-21"}],"sources":[{"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":"Remote attackers can inject arbitrary scripts via the query_string parameter in FusionPBX, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2020-21053/"}
