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-2017-16821 in the wild and no public exploit code.\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-2017-16821/ (Markdown: https://insights.sbomify.com/CVE-2017-16821/index.md)","id":"CVE-2017-16821","markdown":"https://insights.sbomify.com/CVE-2017-16821/index.md","name":"CVE-2017-16821","record":{"aliases":["GHSA-2jpm-mx7w-4vr7"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Symphony blog platform","requires_auth":"low_privilege","summary":"Cross-site scripting in Symphony admin console allows attackers to execute scripts via crafted headers, potentially compromising admin accounts.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"symphony","vendor":"b3log"}],"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":"b3log Symphony (aka Sym) 2.2.0 has XSS in processor/AdminProcessor.java in the admin console, as demonstrated by a crafted X-Forwarded-For HTTP header that is mishandled during display of a client IP address in /admin/user/userid.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2017-16821","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2017-16826"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2017-16820"},"products":["n/a"],"published":"2017-11-15","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2024-23049","kev_date_added":null,"published":"2024-02-05"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2018-10469","kev_date_added":null,"published":"2018-04-27"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2019-17488","kev_date_added":null,"published":"2019-10-10"},{"cvss_score":6.1,"headline":"Moderate severity vulnerability that affects org.b3log:symphony","id":"CVE-2019-9142","kev_date_added":null,"published":"2019-02-25"},{"cvss_score":4.8,"headline":"Cross-site scripting in n/a","id":"CVE-2018-16249","kev_date_added":null,"published":"2019-06-20"}],"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":"2024-09-16","vendors":["n/a"]},"summary":"Cross-site scripting in Symphony admin console allows attackers to execute scripts via crafted headers, potentially compromising admin accounts.","url":"https://insights.sbomify.com/CVE-2017-16821/"}
