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-2021-32536 in the wild and no public exploit code.\n\nAffected product: MCUsystem. 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-2021-32536/ (Markdown: https://insights.sbomify.com/CVE-2021-32536/index.md)","id":"CVE-2021-32536","markdown":"https://insights.sbomify.com/CVE-2021-32536/index.md","name":"CVE-2021-32536","record":{"aliases":["GHSA-2788-q3c5-xfcj"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MCU Technologies MCUsystem","requires_auth":"none","summary":"Remote attackers can inject JavaScript into the login page of MCUsystem, enabling reflected XSS attacks without requiring privileges.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"mcusystem","vendor":"mcusystem"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","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":"The login page in the MCUsystem does not filter with special characters, which allows remote attackers can inject JavaScript without privilege and thus perform reflected XSS attacks.","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":"MCU Technologies MCUsystem - Reflected XSS","id":"CVE-2021-32536","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Realtek High definition audio Windows driver crashed","id":"CVE-2021-32537"},"packages":[],"prev":{"headline":"QSAN SANOS - Use of Hard-coded Credentials","id":"CVE-2021-32535"},"products":["MCUsystem"],"published":"2021-06-18","related":[],"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":["MCU Technologies"]},"summary":"Remote attackers can inject JavaScript into the login page of MCUsystem, enabling reflected XSS attacks without requiring privileges.","url":"https://insights.sbomify.com/CVE-2021-32536/"}
