An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-39421 exists.\n\nAffected product: n/a. 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-2021-39421/ (Markdown: https://insights.sbomify.com/CVE-2021-39421/index.md)","id":"CVE-2021-39421","markdown":"https://insights.sbomify.com/CVE-2021-39421/index.md","name":"CVE-2021-39421","record":{"aliases":["GHSA-gcxp-88pw-5248"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Document Management System","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in SeedDMS via XSS, potentially compromising user sessions and data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"seeddms","vendor":"seeddms"}],"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":"A cross-site scripting (XSS) vulnerability in SeedDMS v6.0.15 allows attackers to execute arbitrary web scripts or HTML via a crafted payload.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2021-39421","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Open redirect in n/a","id":"CVE-2021-39425"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-39420"},"products":["n/a"],"published":"2023-07-24","related":[{"cvss_score":9.8,"headline":"Weak cryptography in n/a","id":"CVE-2022-44938","kev_date_added":null,"published":"2022-12-08"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2021-33223","kev_date_added":null,"published":"2023-06-07"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2018-12940","kev_date_added":null,"published":"2018-07-31"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2018-12941","kev_date_added":null,"published":"2018-07-31"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2018-12942","kev_date_added":null,"published":"2018-07-31"},{"cvss_score":7.5,"headline":"File upload in n/a","id":"CVE-2019-12744","kev_date_added":null,"published":"2019-06-20"},{"cvss_score":7.2,"headline":"Code injection in n/a","id":"CVE-2025-45752","kev_date_added":null,"published":"2025-05-21"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-24","vendors":["n/a"]},"summary":"Attackers can execute arbitrary scripts in SeedDMS via XSS, potentially compromising user sessions and data.","url":"https://insights.sbomify.com/CVE-2021-39421/"}
