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-2025-52435 in the wild and no public exploit code.\n\nAffected product: Apache Mynewt NimBLE. 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-2025-52435/ (Markdown: https://insights.sbomify.com/CVE-2025-52435/index.md)","id":"CVE-2025-52435","markdown":"https://insights.sbomify.com/CVE-2025-52435/index.md","name":"CVE-2025-52435","record":{"aliases":["GHSA-5c5p-g26h-xx2f"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Bluetooth Low Energy stack","requires_auth":"none","summary":"An attacker can eavesdrop on Bluetooth Low Energy communications due to improper handling of encryption pause procedures in Apache NimBLE.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"nimble","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-5","name":"J2EE Misconfiguration: Data Transmission Without Encryption"}],"description":"J2EE Misconfiguration: Data Transmission Without Encryption vulnerability in Apache NimBLE.\n\nImproper handling of Pause Encryption procedure on Link Layer results in a previously encrypted connection being left in un-encrypted state allowing an eavesdropper to observe the remainder of the exchange.\nThis issue affects Apache NimBLE: through \u003c= 1.8.0.\n\nUsers are recommended to upgrade to version 1.9.0, which fixes the issue.","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":"Apache Mynewt NimBLE: Invalid error handling in pause encryption procedure in NimBLE controller","id":"CVE-2025-52435","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in FortiSandbox","id":"CVE-2025-52436"},"packages":[],"prev":{"headline":"Apache Tomcat: APR/Native Connector crash leading to DoS","id":"CVE-2025-52434"},"products":["Apache Mynewt NimBLE"],"published":"2026-01-10","related":[{"cvss_score":8.8,"headline":"Apache NimBLE: Incorrect data validation in BASS add/modify source operation","id":"CVE-2026-45813","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":8.1,"headline":"Apache Mynewt NimBLE: Incorrect handling of SMP Security Request could lead to undesirable pairing","id":"CVE-2025-62235","kev_date_added":null,"published":"2026-01-10"},{"cvss_score":7.5,"headline":"Apache NimBLE: Buffer overflow in socket HCI transport","id":"CVE-2026-45811","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":7.5,"headline":"Apache NimBLE: Remote reachable assertion in ATT Read Multiple Variable Response handler","id":"CVE-2026-45815","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":7.5,"headline":"Apache NimBLE: NULL pointer dereference vulnerability in SMP LTK request","id":"CVE-2026-45816","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":7.5,"headline":"Apache Mynewt NimBLE: NULL Pointer Dereference in NimBLE host HCI layer","id":"CVE-2025-53477","kev_date_added":null,"published":"2026-01-10"}],"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":"2026-01-12","vendors":["Apache Software Foundation"]},"summary":"An attacker can eavesdrop on Bluetooth Low Energy communications due to improper handling of encryption pause procedures in Apache NimBLE.","url":"https://insights.sbomify.com/CVE-2025-52435/"}
