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-2026-27867 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-2026-27867/ (Markdown: https://insights.sbomify.com/CVE-2026-27867/index.md)","id":"CVE-2026-27867","markdown":"https://insights.sbomify.com/CVE-2026-27867/index.md","name":"CVE-2026-27867","record":{"aliases":["GHSA-jj76-67xg-c9gj"],"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":"low_privilege","summary":"An attacker can inject malicious scripts via the cmdcookie parameter in the upgrade interface, potentially executing code or bypassing security controls.","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:L/UI:A/VC:L/VI:L/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 firmware version could inject\na specific payload via the parameter \"cmdcookie\" withing the /upgrade/index.html resulting in to a Cross-Site Scripting (XSS). This issue affects Regesta Smart HD-PLC - TLDPH16D2: \n11.02.06.00.02","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 THE CMDCOOKIE PARAMETER REGESTA SMART HD-PLC OF TELDAT","id":"CVE-2026-27867","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"PUBLICATION OF SENSITIVE INFORMATION ON REGESTA SMART HD-PLC OF TELDAT","id":"CVE-2026-27868"},"packages":[],"prev":{"headline":"Other in OX Dovecot Pro","id":"CVE-2026-27860"},"products":["Regesta Smart HD-PLC - TLDPH16D2"],"published":"2026-09-25","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":"2026-09-25","vendors":["Teldat"]},"summary":"An attacker can inject malicious scripts via the cmdcookie parameter in the upgrade interface, potentially executing code or bypassing security controls.","url":"https://insights.sbomify.com/CVE-2026-27867/"}
