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-2021-34582 in the wild and no public exploit code.\n\nAffected product: PHOENIX CONTACT FL MGUARD. 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-2021-34582/ (Markdown: https://insights.sbomify.com/CVE-2021-34582/index.md)","id":"CVE-2021-34582","markdown":"https://insights.sbomify.com/CVE-2021-34582/index.md","name":"CVE-2021-34582","record":{"aliases":["GHSA-g738-v6qm-gpqv"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial firewall","requires_auth":"high_privilege","summary":"High-privilege users can inject HTML via manipulated certificates in Phoenix Contact FL MGUARD firewalls, enabling cross-site scripting attacks.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"fl_mguard_1102_firmware","vendor":"phoenixcontact"},{"product":"fl_mguard_1105_firmware","vendor":"phoenixcontact"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/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"}],"description":"In Phoenix Contact FL MGUARD 1102 and 1105 in Versions 1.4.0, 1.4.1 and 1.5.0 a user with high privileges can inject HTML code (XSS) through web-based management or the REST API with a manipulated certificate file.","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":"Phoenix Contact: FL MGUARD XSS through web-based management and REST API","id":"CVE-2021-34582","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"CODESYS V2 web server: crafted requests could trigger a heap-based buffer overflow (DoS)","id":"CVE-2021-34583"},"packages":[],"prev":{"headline":"WAGO: Denial of Service vulnerability inside the OpenSSL implementation","id":"CVE-2021-34581"},"products":["FL MGUARD"],"published":"2021-11-10","related":[{"cvss_score":7.5,"headline":"Phoenix Contact: FL MGUARD lack of memory release in remote logging functionality","id":"CVE-2021-34598","kev_date_added":null,"published":"2021-11-10"}],"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":"2024-09-16","vendors":["PHOENIX CONTACT"]},"summary":"High-privilege users can inject HTML via manipulated certificates in Phoenix Contact FL MGUARD firewalls, enabling cross-site scripting attacks.","url":"https://insights.sbomify.com/CVE-2021-34582/"}
