It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-12687 in the wild and no public exploit code.\n\nAffected product: TeamViewer DEX. 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-2025-12687/ (Markdown: https://insights.sbomify.com/CVE-2025-12687/index.md)","id":"CVE-2025-12687","markdown":"https://insights.sbomify.com/CVE-2025-12687/index.md","name":"CVE-2025-12687","record":{"aliases":["GHSA-9f92-cqmm-3frg"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TeamViewer DEX Client","requires_auth":"none","summary":"Attackers can crash the TeamViewer DEX Client Content Distribution Service via a crafted command, causing service termination.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TV","cpe":[{"product":"digital_employee_experience","vendor":"teamviewer"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 25.11 for Windows allows malicious actors to cause a denial of service (application crash) via a crafted command, resulting in service termination.","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":"Denial-of-Service Vulnerability in NomadBranch.exe","id":"CVE-2025-12687","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"DoS in Calls plugin via malformed UTF-8 in WebSocket request","id":"CVE-2025-12689"},"packages":[],"prev":{"headline":"Memory corruption in BeeStation OS","id":"CVE-2025-12686"},"products":["DEX"],"published":"2025-12-11","related":[{"cvss_score":8.8,"headline":"File Hash Validation Bypass in NomadBranch.exe","id":"CVE-2025-44016","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":7.2,"headline":"Command Injection in 1E-Explorer-TachyonCore-DevicesListeningOnAPort Instruction","id":"CVE-2025-64986","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":7.2,"headline":"Command Injection in 1E-Explorer-TachyonCore-CheckSimpleIoC Instruction","id":"CVE-2025-64987","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":7.2,"headline":"Command Injection in 1E-Nomad-GetCmContentLocations Instruction","id":"CVE-2025-64988","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":7.2,"headline":"Command Injection in 1E-Explorer-TachyonCore-FindFileBySizeAndHash Instruction","id":"CVE-2025-64989","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":6.8,"headline":"Command Injection in 1E-Nomad-RunPkgStatusRequest Instruction in TeamViewer DEX","id":"CVE-2026-23571","kev_date_added":null,"published":"2026-01-29"},{"cvss_score":6.8,"headline":"Command Injection in 1E-Explorer-TachyonCore-LogoffUser Instruction","id":"CVE-2025-64990","kev_date_added":null,"published":"2025-12-11"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-11","vendors":["TeamViewer"]},"summary":"Attackers can crash the TeamViewer DEX Client Content Distribution Service via a crafted command, causing service termination.","url":"https://insights.sbomify.com/CVE-2025-12687/"}
