An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-34036 exists.\n\nAffected product: Shenzhen TVT CCTV-DVR. 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-2025-34036/ (Markdown: https://insights.sbomify.com/CVE-2025-34036/index.md)","id":"CVE-2025-34036","markdown":"https://insights.sbomify.com/CVE-2025-34036/index.md","name":"CVE-2025-34036","record":{"aliases":["GHSA-ppp6-57cw-px5q"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"CCTV DVR","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary commands as root on Shenzhen TVT CCTV-DVRs via unsanitized input in the web server's language extraction feature.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"td-2004ts-cl-c_firmware","vendor":"tvt"},{"product":"td-2004ts-cl_firmware","vendor":"tvt"},{"product":"td-2008ts-cl_firmware","vendor":"tvt"},{"product":"td-2104ts-cl-a_firmware","vendor":"tvt"},{"product":"td-2104ts-cl_firmware","vendor":"tvt"},{"product":"td-2104ts-hc_firmware","vendor":"tvt"},{"product":"td-2104ts-hp_firmware","vendor":"tvt"},{"product":"td-2108ts-cl-a_firmware","vendor":"tvt"},{"product":"td-2108ts-cl_firmware","vendor":"tvt"},{"product":"td-2108ts-hc_firmware","vendor":"tvt"},{"product":"td-2108ts-hp_firmware","vendor":"tvt"},{"product":"td-2116te-hp_firmware","vendor":"tvt"},{"product":"td-2116ts-cl_firmware","vendor":"tvt"},{"product":"td-2116ts-hc_firmware","vendor":"tvt"},{"product":"td-2704ts-hc_firmware","vendor":"tvt"},{"product":"td-2704ts-hp_firmware","vendor":"tvt"},{"product":"td-2708te-hk_firmware","vendor":"tvt"},{"product":"td-2708te-hp_firmware","vendor":"tvt"},{"product":"td-2708ts-hc_firmware","vendor":"tvt"},{"product":"td-2708ts-hp_firmware","vendor":"tvt"},{"product":"td-2716tc-hc_firmware","vendor":"tvt"},{"product":"td-2716tc-hp_firmware","vendor":"tvt"},{"product":"td-2716td-hc_firmware","vendor":"tvt"},{"product":"td-2716te-hc-a_firmware","vendor":"tvt"},{"product":"td-2716te-hc_firmware","vendor":"tvt"},{"product":"td-2716te-hp-a_firmware","vendor":"tvt"},{"product":"td-2716te-hp_firmware","vendor":"tvt"},{"product":"td-2732tc-hc_firmware","vendor":"tvt"},{"product":"td-2732td-hc_firmware","vendor":"tvt"},{"product":"td-2932td-hp_firmware","vendor":"tvt"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An OS command injection vulnerability exists in white-labeled DVRs manufactured by TVT, affecting a custom HTTP service called \"Cross Web Server\" that listens on TCP ports 81 and 82. The web interface fails to sanitize input in the URI path passed to the language extraction functionality. When the server processes a request to /language/[lang]/index.html, it uses the [lang] input unsafely in a tar extraction command without proper escaping. This allows an unauthenticated remote attacker to inject shell commands and achieve arbitrary command execution as root. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Shenzhen TVT CCTV-DVR Command Injection","id":"CVE-2025-34036","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Linksys Routers E/WAG/WAP/WES/WET/WRT-Series","id":"CVE-2025-34037"},"packages":[],"prev":{"headline":"EnGenius EnShare IoT Gigabit Cloud Service Command Injection","id":"CVE-2025-34035"},"products":["CCTV-DVR"],"published":"2025-06-24","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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-07","vendors":["Shenzhen TVT"]},"summary":"Unauthenticated attackers can execute arbitrary commands as root on Shenzhen TVT CCTV-DVRs via unsanitized input in the web server's language extraction feature.","url":"https://insights.sbomify.com/CVE-2025-34036/"}
