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-2017-16856 in the wild and no public exploit code.\n\nAffected product: Atlassian Confluence. 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-2017-16856/ (Markdown: https://insights.sbomify.com/CVE-2017-16856/index.md)","id":"CVE-2017-16856","markdown":"https://insights.sbomify.com/CVE-2017-16856/index.md","name":"CVE-2017-16856","record":{"aliases":["GHSA-7x5g-hwfp-5cwv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Confluence","requires_auth":"none","summary":"Remote attackers can inject arbitrary HTML or JavaScript via the RSS Feed macro, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"confluence","vendor":"atlassian"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The RSS Feed macro in Atlassian Confluence before version 6.5.2 allows remote attackers to inject arbitrary HTML or JavaScript via cross site scripting (XSS) vulnerabilities in various rss properties which were used as links without restriction on their scheme.","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 Confluence","id":"CVE-2017-16856","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2017"},"n_packages":0,"n_references":2,"next":{"headline":"Race condition in Auto-Unapprove Plugin (for Bitbucket Server)","id":"CVE-2017-16857"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2017-16854"},"products":["Confluence"],"published":"2017-12-05","related":[{"cvss_score":9.8,"headline":"Server-side request forgery in Confluence Server","id":"CVE-2019-3395","kev_date_added":null,"published":"2019-03-25"},{"cvss_score":8.8,"headline":"Path traversal in Confluence Server","id":"CVE-2019-3394","kev_date_added":null,"published":"2019-08-29"},{"cvss_score":7.8,"headline":"Privilege escalation in Confluence Data Center","id":"CVE-2019-20406","kev_date_added":null,"published":"2020-02-06"},{"cvss_score":6.5,"headline":"Other in Confluence Server","id":"CVE-2019-15006","kev_date_added":null,"published":"2019-12-19"},{"cvss_score":6.1,"headline":"Cross-site scripting in Confluence","id":"CVE-2017-18085","kev_date_added":null,"published":"2018-02-02"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2017-18086","kev_date_added":null,"published":"2018-02-02"}],"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":["Atlassian"]},"summary":"Remote attackers can inject arbitrary HTML or JavaScript via the RSS Feed macro, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2017-16856/"}
