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-2021-40541 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-40541/ (Markdown: https://insights.sbomify.com/CVE-2021-40541/index.md)","id":"CVE-2021-40541","markdown":"https://insights.sbomify.com/CVE-2021-40541/index.md","name":"CVE-2021-40541","record":{"aliases":["GHSA-gr69-fgwp-qxq8"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"PHPFusion CMS","requires_auth":"none","summary":"An authenticated user can trigger cross-site scripting in PHPFusion by appending double slashes to text, potentially leading to session hijacking or malicious script execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"phpfusion","vendor":"php-fusion"}],"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":"PHPFusion 9.03.110 is affected by cross-site scripting (XSS) in the preg patterns filter html tag without \"//\" in descript() function An authenticated user can trigger XSS by appending \"//\" in the end of text.","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 n/a","id":"CVE-2021-40541","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-40542"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2021-40540"},"products":["n/a"],"published":"2021-10-11","related":[{"cvss_score":9.6,"headline":"Unverified Password Change in phpfusion/phpfusion","id":"CVE-2022-3152","kev_date_added":null,"published":"2022-09-07"},{"cvss_score":9.6,"headline":"Cross-site scripting in n/a","id":"CVE-2020-23754","kev_date_added":null,"published":"2021-11-02"},{"cvss_score":8.8,"headline":"Local file Inclusion (LFI) in Forum Infusion via Directory Traversal","id":"CVE-2023-2453","kev_date_added":null,"published":"2023-09-05"},{"cvss_score":8.6,"headline":"PHP-Fusion 9.03.50 - 'panels.php' Eval Injection","id":"CVE-2020-37137","kev_date_added":null,"published":"2026-02-05"},{"cvss_score":7.2,"headline":"File upload in n/a","id":"CVE-2021-40188","kev_date_added":null,"published":"2021-10-11"},{"cvss_score":7.2,"headline":"File upload in n/a","id":"CVE-2021-40189","kev_date_added":null,"published":"2021-10-11"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2014-8597","kev_date_added":null,"published":"2022-02-17"}],"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":["n/a"]},"summary":"An authenticated user can trigger cross-site scripting in PHPFusion by appending double slashes to text, potentially leading to session hijacking or malicious script execution.","url":"https://insights.sbomify.com/CVE-2021-40541/"}
