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-2025-3899 in the wild and no public exploit code.\n\nAffected product: Schneider Electric Modicon Controllers M241/M251. 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-2025-3899/ (Markdown: https://insights.sbomify.com/CVE-2025-3899/index.md)","id":"CVE-2025-3899","markdown":"https://insights.sbomify.com/CVE-2025-3899/index.md","name":"CVE-2025-3899","record":{"aliases":["GHSA-j34m-g9vq-47p3"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon PLC","requires_auth":"low_privilege","summary":"Authenticated attackers can inject scripts into the Modicon web server certificates page to read or modify victim browser data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability\nexists in Certificates page on Webserver that could cause an unvalidated data injected by authenticated\nmalicious user leading to modify or read data in a victim’s browser.","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 Modicon Controllers M241/M251","id":"CVE-2025-3899","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Colorbox - Moderately critical - Cross Site Scripting - SA-CONTRIB-2025-041","id":"CVE-2025-3900"},"packages":[],"prev":{"headline":"Denial of service in Modicon Controllers M241/M251","id":"CVE-2025-3898"},"products":["Modicon Controllers M241/M251"],"published":"2025-06-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-10","vendors":["Schneider Electric"]},"summary":"Authenticated attackers can inject scripts into the Modicon web server certificates page to read or modify victim browser data.","url":"https://insights.sbomify.com/CVE-2025-3899/"}
