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-2017-8298 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- austintoddj/canvas (Packagist): affected all versions; no fix listed\n- austintoddj/canvas (Packagist): affected all versions; no fix listed\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-2017-8298/ (Markdown: https://insights.sbomify.com/CVE-2017-8298/index.md)","id":"CVE-2017-8298","markdown":"https://insights.sbomify.com/CVE-2017-8298/index.md","name":"CVE-2017-8298","record":{"aliases":["GHSA-3657-q433-mmpx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Canvas CMS","requires_auth":"low_privilege","summary":"Cross-site scripting vulnerability in Canvas CMS allows attackers to inject malicious scripts via post titles, content, tags, or user creation fields.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"canvas","vendor":"cnvs"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/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":"cnvs.io Canvas 3.3.0 has XSS in the title and content fields of a \"Posts \u003e Add New\" action, and during creation of new tags and users.","ecosystems":["Packagist"],"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":"Canvs Canvas Cross-site Scripting (XSS) via title and content fields","id":"CVE-2017-8298","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2017"},"n_packages":2,"n_references":1,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2017-8301"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":[],"last_affected":[],"package":"austintoddj/canvas","purl":null,"source":"GHSA-3657-q433-mmpx"},{"ecosystem":"Packagist","fixed":[],"introduced":[],"last_affected":[],"package":"austintoddj/canvas","purl":"pkg:composer/austintoddj/canvas","source":"GHSA-3657-q433-mmpx"}],"prev":{"headline":"Path traversal in n/a","id":"CVE-2017-8297"},"products":["n/a"],"published":"2017-04-27","related":[{"cvss_score":5.4,"headline":"Canvs Canvas XSS Vulnerability","id":"CVE-2017-1000507","kev_date_added":null,"published":"2018-02-09"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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 vulnerability in Canvas CMS allows attackers to inject malicious scripts via post titles, content, tags, or user creation fields.","url":"https://insights.sbomify.com/CVE-2017-8298/"}
