GROWI (v4.2 Series), published on 10 Mar 2021. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20673 in the wild and no public exploit code.\n\nAffected product: WESEEK, Inc. GROWI (v4.2 Series). 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-2021-20673/ (Markdown: https://insights.sbomify.com/CVE-2021-20673/index.md)","id":"CVE-2021-20673","markdown":"https://insights.sbomify.com/CVE-2021-20673/index.md","name":"CVE-2021-20673","record":{"aliases":["GHSA-m48w-5q6f-f285"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"GROWI wiki platform","requires_auth":"high_privilege","summary":"Authenticated attackers can inject arbitrary scripts into the GROWI admin page, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"growi","vendor":"weseek"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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 in Admin Page of GROWI (v4.2 Series) versions from v4.2.0 to v4.2.7 allows remote authenticated attackers to inject an arbitrary script via unspecified vectors.","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 (v4.2 Series)","id":"CVE-2021-20673","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in Installer of MagicConnect Client program","id":"CVE-2021-20674"},"packages":[],"prev":{"headline":"Cross-site scripting in GROWI (v4.2 Series)","id":"CVE-2021-20672"},"products":["GROWI (v4.2 Series)"],"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":"Authenticated attackers can inject arbitrary scripts into the GROWI admin page, potentially leading to code execution or account takeover.","url":"https://insights.sbomify.com/CVE-2021-20673/"}
