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-2020-9311 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- silverstripe/cms (Packagist): affected all versions up to 4.5.0; no fix listed\n- silverstripe/cms (Packagist): affected all versions up to 4.5.0; no fix listed\n- silverstripe (Bitnami): affected from 3.0.0; fixed in 3.7.5\n- silverstripe/framework (Packagist): affected from 3.0.0; fixed in 3.7.5\n- silverstripe/framework (Packagist): affected from 3.0.0; fixed in 3.7.5\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-2020-9311/ (Markdown: https://insights.sbomify.com/CVE-2020-9311/index.md)","id":"CVE-2020-9311","markdown":"https://insights.sbomify.com/CVE-2020-9311/index.md","name":"CVE-2020-9311","record":{"aliases":["BIT-silverstripe-2020-9311","GHSA-2pw2-qpcp-m47x"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SilverStripe CMS","requires_auth":"low_privilege","summary":"Authenticated users can inject malicious scripts via profile information, leading to XSS attacks against other users in SilverStripe CMS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"silverstripe","vendor":"silverstripe"}],"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":"In SilverStripe through 4.5, malicious users with a valid Silverstripe CMS login (usually CMS access) can craft profile information which can lead to XSS for other users through specially crafted login form URLs.","ecosystems":["Bitnami","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":"Silverstripe CMS XSS Vulnerability","id":"CVE-2020-9311","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"silverstripe:silverstripe","products":["silverstripe:silverstripe"],"type":"xss","year":"2020"},"n_packages":5,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-9314"},"packages":[{"ecosystem":"Bitnami","fixed":["3.7.5"],"introduced":["3.0.0"],"last_affected":[],"package":"silverstripe","purl":"pkg:bitnami/silverstripe","source":"BIT-silverstripe-2020-9311"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["4.5.0"],"package":"silverstripe/cms","purl":null,"source":"GHSA-2pw2-qpcp-m47x"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["4.5.0"],"package":"silverstripe/cms","purl":"pkg:composer/silverstripe/cms","source":"GHSA-2pw2-qpcp-m47x"},{"ecosystem":"Packagist","fixed":["3.7.5"],"introduced":["3.0.0"],"last_affected":[],"package":"silverstripe/framework","purl":null,"source":"GHSA-2pw2-qpcp-m47x"},{"ecosystem":"Packagist","fixed":["3.7.5"],"introduced":["3.0.0"],"last_affected":[],"package":"silverstripe/framework","purl":"pkg:composer/silverstripe/framework","source":"GHSA-2pw2-qpcp-m47x"}],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-9310"},"products":["n/a"],"published":"2020-07-15","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2007-2321","kev_date_added":null,"published":"2007-04-27"},{"cvss_score":9.8,"headline":"Missing warning can lead to unauthenticated admin access in SilverStripe","id":"CVE-2019-12204","kev_date_added":null,"published":"2019-09-25"},{"cvss_score":9.8,"headline":"Silverstripe Framework SQLi Vulnerability","id":"CVE-2019-5715","kev_date_added":null,"published":"2019-04-11"},{"cvss_score":8.8,"headline":"Silverstripe CSRF Protection Bypass via GraphQL","id":"CVE-2019-12437","kev_date_added":null,"published":"2020-02-19"},{"cvss_score":7.5,"headline":"Silverstripe CMS information disclosure","id":"CVE-2020-6164","kev_date_added":null,"published":"2020-07-15"},{"cvss_score":7.5,"headline":"SilverStripe Folders migrated from 3.x may be unsafe to upload to","id":"CVE-2020-9280","kev_date_added":null,"published":"2020-04-15"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2011-4960","kev_date_added":null,"published":"2012-09-17"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":["n/a"]},"summary":"Authenticated users can inject malicious scripts via profile information, leading to XSS attacks against other users in SilverStripe CMS.","url":"https://insights.sbomify.com/CVE-2020-9311/"}
