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-2025-27810 in the wild and no public exploit code.\n\nAffected product: Arm Mbed Tls. 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-2025-27810/ (Markdown: https://insights.sbomify.com/CVE-2025-27810/index.md)","id":"CVE-2025-27810","markdown":"https://insights.sbomify.com/CVE-2025-27810/index.md","name":"CVE-2025-27810","record":{"aliases":["ALPINE-CVE-2025-27810","DEBIAN-CVE-2025-27810","GHSA-vvqm-mmw4-qwg5","JLSEC-2025-187","ROOT-OS-DEBIAN-12-CVE-2025-27810","UBUNTU-CVE-2025-27810"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"TLS library","requires_auth":"none","summary":"Attackers can bypass TLS authentication and perform replays due to uninitialized memory usage in Mbed TLS during specific error conditions.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mbed_tls","vendor":"arm"},{"product":"mbed_tls","vendor":"trustedfirmware"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"Mbed TLS before 2.28.10 and 3.x before 3.6.3, in some cases of failed memory allocation or hardware errors, uses uninitialized stack memory to compose the TLS Finished message, potentially leading to authentication bypasses such as replays.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Security feature bypass in mbedtls","id":"CVE-2025-27810","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"arm:mbed_tls","products":["arm:mbed_tls"],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2025-27811"},"packages":[],"prev":{"headline":"Security feature bypass in mbedtls","id":"CVE-2025-27809"},"products":["mbedtls"],"published":"2025-03-25","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2026-34877","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-46393","kev_date_added":null,"published":"2022-12-15"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2021-44732","kev_date_added":null,"published":"2021-12-20"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-18187","kev_date_added":null,"published":"2018-02-14"},{"cvss_score":9.8,"headline":"Memory corruption in ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0","id":"CVE-2018-0487","kev_date_added":null,"published":"2018-02-13"},{"cvss_score":9.8,"headline":"Memory corruption in ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0","id":"CVE-2018-0488","kev_date_added":null,"published":"2018-02-13"},{"cvss_score":9.1,"headline":"Weak cryptography in n/a","id":"CVE-2026-34872","kev_date_added":null,"published":"2026-04-01"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-25","vendors":["Mbed"]},"summary":"Attackers can bypass TLS authentication and perform replays due to uninitialized memory usage in Mbed TLS during specific error conditions.","url":"https://insights.sbomify.com/CVE-2025-27810/"}
