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-2020-5528 in the wild and no public exploit code.\n\nAffected product: Six Apart Ltd Movable Type series. 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-2020-5528/ (Markdown: https://insights.sbomify.com/CVE-2020-5528/index.md)","id":"CVE-2020-5528","markdown":"https://insights.sbomify.com/CVE-2020-5528/index.md","name":"CVE-2020-5528","record":{"aliases":["GHSA-5928-fcw8-m7f4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Movable Type CMS","requires_auth":"none","summary":"Remote attackers can inject arbitrary web script or HTML into the block and rich text editors via crafted URLs, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"movable_type","vendor":"sixapart"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"Cross-site scripting vulnerability in Movable Type series (Movable Type 7 r.4603 and earlier (Movable Type 7), Movable Type 6.5.2 and earlier (Movable Type 6.5), Movable Type Advanced 7 r.4603 and earlier (Movable Type Advanced 7), Movable Type Advanced 6.5.2 and earlier (Movable Type Advanced 6.5), Movable Type Premium 1.26 and earlier (Movable Type Premium), and Movable Type Premium Advanced 1.26 and earlier (Movable Type Premium Advanced)) allows remote attackers to inject arbitrary web script or HTML in the block editor and the rich text editor via a specially crafted URL.","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 Movable Type series","id":"CVE-2020-5528","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Code execution vulnerability in HtmlUnit","id":"CVE-2020-5529"},"packages":[],"prev":{"headline":"Denial of service in MELSOFT transmission port (UDP/IP) of multiple Mitsubishi Electric MELSEC series","id":"CVE-2020-5527"},"products":["Movable Type series"],"published":"2020-02-06","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-0752","kev_date_added":null,"published":"2009-03-03"},{"cvss_score":9.8,"headline":"Command injection in Movable Type XMLRPC API","id":"CVE-2022-38078","kev_date_added":null,"published":"2022-08-24"},{"cvss_score":9.8,"headline":"Command injection in Movable Type","id":"CVE-2021-20837","kev_date_added":null,"published":"2021-10-26"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2016-5742","kev_date_added":null,"published":"2017-01-23"},{"cvss_score":9.3,"headline":"Code injection in Movable Type","id":"CVE-2026-25776","kev_date_added":null,"published":"2026-04-08"},{"cvss_score":8.8,"headline":"Cross-site request forgery in Movable Type","id":"CVE-2020-5576","kev_date_added":null,"published":"2020-05-14"},{"cvss_score":8.8,"headline":"File upload in Movable Type","id":"CVE-2020-5577","kev_date_added":null,"published":"2020-05-14"}],"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":"2024-08-04","vendors":["Six Apart Ltd"]},"summary":"Remote attackers can inject arbitrary web script or HTML into the block and rich text editors via crafted URLs, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2020-5528/"}
