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-2020-5298 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- october/backend (Packagist): affected from 1.0.319; fixed in 1.0.466\n- october/backend (Packagist): affected from 1.0.319; fixed in 1.0.466\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-2020-5298/ (Markdown: https://insights.sbomify.com/CVE-2020-5298/index.md)","id":"CVE-2020-5298","markdown":"https://insights.sbomify.com/CVE-2020-5298/index.md","name":"CVE-2020-5298","record":{"aliases":["GHSA-gg6x-xx78-448c"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OctoberCMS","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary scripts in victim browsers via malicious CSV imports in OctoberCMS, requiring user interaction.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"october","vendor":"octobercms"}],"cvss":{"score":4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/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"},{"id":"CWE-87","name":"Improper Neutralization of Alternate XSS Syntax"}],"description":"In OctoberCMS (october/october composer package) versions from 1.0.319 and before 1.0.466, a user with the ability to use the import functionality of the `ImportExportController` behavior can be socially engineered by an attacker to upload a maliciously crafted CSV file which could result in a reflected XSS attack on the user in question Issue has been patched in Build 466 (v1.0.466).","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":true,"headline":"Reflected XSS when importing CSV in OctoberCMS","id":"CVE-2020-5298","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"octobercms:october","products":["octobercms:october"],"type":"xss","year":"2020"},"n_packages":2,"n_references":4,"next":{"headline":"Potential CSV Injection vector in OctoberCMS","id":"CVE-2020-5299"},"packages":[{"ecosystem":"Packagist","fixed":["1.0.466"],"introduced":["1.0.319"],"last_affected":[],"package":"october/backend","purl":null,"source":"GHSA-gg6x-xx78-448c"},{"ecosystem":"Packagist","fixed":["1.0.466"],"introduced":["1.0.319"],"last_affected":[],"package":"october/backend","purl":"pkg:composer/october/backend","source":"GHSA-gg6x-xx78-448c"}],"prev":{"headline":"Upload whitelisted files to any directory in OctoberCMS","id":"CVE-2020-5297"},"products":["october"],"published":"2020-06-03","related":[{"cvss_score":8.2,"headline":"October CMS Improper Authentication","id":"CVE-2021-32648","kev_date_added":"2022-01-18","published":"2021-08-26"},{"cvss_score":9.8,"headline":"October CMS Session ID not invalidated after logout","id":"CVE-2021-3311","kev_date_added":null,"published":"2021-02-05"},{"cvss_score":9.8,"headline":"October CMS File Upload Vulnerability","id":"CVE-2017-1000194","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2017-1000196","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2017-1000197","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":9.1,"headline":"October CMS safe mode bypass using Twig sandbox escape","id":"CVE-2023-44382","kev_date_added":null,"published":"2023-12-01"},{"cvss_score":8.8,"headline":"Authenticated file write leads to remote code execution in october/system","id":"CVE-2021-32649","kev_date_added":null,"published":"2022-01-14"}],"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":"2024-08-04","vendors":["octobercms"]},"summary":"Attackers can execute arbitrary scripts in victim browsers via malicious CSV imports in OctoberCMS, requiring user interaction.","url":"https://insights.sbomify.com/CVE-2020-5298/"}
