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-2021-42535 in the wild and no public exploit code.\n\nAffected product: VISAM VBASE Pro-RT/ Server-RT (Web Remote). 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-2021-42535/ (Markdown: https://insights.sbomify.com/CVE-2021-42535/index.md)","id":"CVE-2021-42535","markdown":"https://insights.sbomify.com/CVE-2021-42535/index.md","name":"CVE-2021-42535","record":{"aliases":["GHSA-8vjc-vph9-rg4j"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"VISAM VBASE Editor","requires_auth":"none","summary":"An attacker can inject malicious scripts into the VISAM VBASE Editor web interface, potentially compromising user sessions or executing code.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"vbase_web-remote","vendor":"visam"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"VISAM VBASE version 11.6.0.6 does not neutralize or incorrectly neutralizes user-controllable input before the data is placed in output used as a public-facing webpage.","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":"VISAM VBASE Editor Cross Site Scripting","id":"CVE-2021-42535","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Emerson WirelessHART Gateway","id":"CVE-2021-42536"},"packages":[],"prev":{"headline":"Trane Building Automation Controllers Cross-site Scripting","id":"CVE-2021-42534"},"products":["VBASE Pro-RT/ Server-RT (Web Remote)"],"published":"2022-07-27","related":[{"cvss_score":7.4,"headline":"VISAM VBASE Editor Improper Access Control","id":"CVE-2021-38417","kev_date_added":null,"published":"2022-07-27"},{"cvss_score":5.9,"headline":"VISAM VBASE Editor Improper Restriction of XML","id":"CVE-2021-42537","kev_date_added":null,"published":"2022-07-27"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-17","vendors":["VISAM"]},"summary":"An attacker can inject malicious scripts into the VISAM VBASE Editor web interface, potentially compromising user sessions or executing code.","url":"https://insights.sbomify.com/CVE-2021-42535/"}
