An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54410 in the wild and no public exploit code.\n\nAffected product: debevv nanoMODBUS. 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-2026-54410/ (Markdown: https://insights.sbomify.com/CVE-2026-54410/index.md)","id":"CVE-2026-54410","markdown":"https://insights.sbomify.com/CVE-2026-54410/index.md","name":"CVE-2026-54410","record":{"aliases":["GHSA-6f53-f2m4-6j2h"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Modbus TCP library","requires_auth":"none","summary":"Remote attackers can trigger a buffer overflow in nanoMODBUS via crafted Modbus frames, potentially leading to code execution or service disruption.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TuranSec","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N/E:P/AU:Y","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-193","name":"Off-by-one Error"}],"description":"nanoMODBUS through v1.23.0 contains an off-by-one buffer overflow in the recv_msg_header function of the Modbus/TCP server that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of the 260-byte receive buffer by sending a crafted MBAP frame whose Length field is set to 255.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"nanoMODBUS Off-by-One Buffer Overflow in recv_msg_header() via Crafted MBAP Length Field","id":"CVE-2026-54410","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Linux-PAM pam_userdb Observable Timing Discrepancy in Plaintext Password Comparison","id":"CVE-2026-54411"},"packages":[],"prev":{"headline":"Auth bypass in UniFi Protect Application","id":"CVE-2026-54409"},"products":["nanoMODBUS"],"published":"2026-06-14","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["debevv"]},"summary":"Remote attackers can trigger a buffer overflow in nanoMODBUS via crafted Modbus frames, potentially leading to code execution or service disruption.","url":"https://insights.sbomify.com/CVE-2026-54410/"}
