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-2026-27870 in the wild and no public exploit code.\n\nAffected product: Teldat Regesta Smart HD-PLC - TLDPH16D2. 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-2026-27870/ (Markdown: https://insights.sbomify.com/CVE-2026-27870/index.md)","id":"CVE-2026-27870","markdown":"https://insights.sbomify.com/CVE-2026-27870/index.md","name":"CVE-2026-27870","record":{"aliases":["GHSA-6mph-64g9-533j"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"HD-PLC network device","requires_auth":"high_privilege","summary":"An attacker can inject JavaScript via the Hostname field in the configuration file, leading to Cross-Site Scripting on the Teldat Regesta Smart HD-PLC.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HackRTU","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"An attacker with access via network to the Regesta Smart HD-PLC of the provider Teldat (in this case, registration action IS required) who has the vulnerable software could, introduce arbitrary JavaScript by injecting a Cross-site Scripting (XSS)  payload into the 'Hostname' field of the configuration file resulting in a XSS in the path /upgrade/query.php?cmd=p+3%3Bversion. This issue affects Regesta Smart HD-PLC - TLDPH16D2: \n11.02.05.10.02.","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 (XSS) VIA MALICIOUS FILE UPLOAD ON REGESTA SMART HD-PLC OF TELDAT","id":"CVE-2026-27870","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"TL280","id":"CVE-2026-27871"},"packages":[],"prev":{"headline":"WEB SERVICE (HTTP) DENIAL OF SERVICE VIA SLOW HEADERS ON REGESTA SMART HD-PLC OF TELDAT","id":"CVE-2026-27869"},"products":["Regesta Smart HD-PLC - TLDPH16D2"],"published":"2026-06-17","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":"2026-07-01","vendors":["Teldat"]},"summary":"An attacker can inject JavaScript via the Hostname field in the configuration file, leading to Cross-Site Scripting on the Teldat Regesta Smart HD-PLC.","url":"https://insights.sbomify.com/CVE-2026-27870/"}
