GROWI, published on 10 Mar 2021. 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-2021-20667 in the wild and no public exploit code.\n\nAffected product: WESEEK, Inc. GROWI. 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-2021-20667/ (Markdown: https://insights.sbomify.com/CVE-2021-20667/index.md)","id":"CVE-2021-20667","markdown":"https://insights.sbomify.com/CVE-2021-20667/index.md","name":"CVE-2021-20667","record":{"aliases":["GHSA-62f6-wgjc-3prq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"GROWI wiki platform","requires_auth":"low_privilege","summary":"Remote authenticated attackers can inject arbitrary scripts via crafted content due to inadequate CSP configuration in GROWI.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"growi","vendor":"weseek"}],"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":"Stored cross-site scripting vulnerability due to inadequate CSP (Content Security Policy) configuration in GROWI versions v4.2.2 and earlier allows remote authenticated attackers to inject an arbitrary script via a specially crafted content.","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 GROWI","id":"CVE-2021-20667","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in GROWI","id":"CVE-2021-20668"},"packages":[],"prev":{"headline":"Cross-site scripting in Movable Type","id":"CVE-2021-20665"},"products":["GROWI"],"published":"2021-03-10","related":[{"cvss_score":9.1,"headline":"SQL injection in GROWI","id":"CVE-2021-20736","kev_date_added":null,"published":"2021-06-22"},{"cvss_score":8.8,"headline":"Cross-site request forgery in GROWI","id":"CVE-2019-5968","kev_date_added":null,"published":"2019-07-05"},{"cvss_score":7.5,"headline":"Information disclosure in GROWI","id":"CVE-2021-20670","kev_date_added":null,"published":"2021-03-10"},{"cvss_score":7.5,"headline":"Denial of service in GROWI","id":"CVE-2020-5682","kev_date_added":null,"published":"2020-12-16"},{"cvss_score":7.5,"headline":"Path traversal in GROWI","id":"CVE-2020-5683","kev_date_added":null,"published":"2020-12-16"},{"cvss_score":7.5,"headline":"Information disclosure in GROWI","id":"CVE-2020-5676","kev_date_added":null,"published":"2020-12-03"},{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2019-13337","kev_date_added":null,"published":"2019-07-09"}],"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":"2024-08-03","vendors":["WESEEK, Inc."]},"summary":"Remote authenticated attackers can inject arbitrary scripts via crafted content due to inadequate CSP configuration in GROWI.","url":"https://insights.sbomify.com/CVE-2021-20667/"}
