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-2020-10932 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-2020-10932/ (Markdown: https://insights.sbomify.com/CVE-2020-10932/index.md)","id":"CVE-2020-10932","markdown":"https://insights.sbomify.com/CVE-2020-10932/index.md","name":"CVE-2020-10932","record":{"aliases":["ALPINE-CVE-2020-10932","DEBIAN-CVE-2020-10932","GHSA-fj9x-f2wx-v38w","JLSEC-2025-201","MGASA-2020-0265","UBUNTU-CVE-2020-10932","openSUSE-SU-2021:0384-1","openSUSE-SU-2021:0397-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mbed TLS library","requires_auth":"low_privilege","summary":"An attacker with side-channel access can recover ECDSA private keys from Mbed TLS, compromising cryptographic security.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mbed_tls","vendor":"arm"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"mbed_tls","vendor":"trustedfirmware"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"},{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by (1) reconstructing the projective coordinate of the result of scalar multiplication by exploiting side channels in the conversion to affine coordinates; (2) using an attack described by Naccache, Smart, and Stern in 2003 to recover a few bits of the ephemeral scalar from those projective coordinates via several measurements; and (3) using a lattice attack to get from there to the long-term ECDSA private key used for the signatures. Typically an attacker would have sufficient access when attacking an SGX enclave and controlling the untrusted OS.","ecosystems":["SUSE:Package Hub 15 SP2","openSUSE:Leap 15.2"],"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":"Information disclosure in n/a","id":"CVE-2020-10932","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"arm:mbed_tls","products":["arm:mbed_tls","debian:debian_linux","fedoraproject:fedora"],"type":"information_disclosure","year":"2020"},"n_packages":2,"n_references":6,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-10933"},"packages":[{"ecosystem":"SUSE:Package Hub 15 SP2","fixed":["2.16.9-bp152.2.3.1"],"introduced":["0"],"last_affected":[],"package":"mbedtls","purl":"pkg:rpm/suse/mbedtls\u0026distro=SUSE%20Package%20Hub%2015%20SP2","source":"openSUSE-SU-2021:0397-1"},{"ecosystem":"openSUSE:Leap 15.2","fixed":["2.16.9-lp152.2.3.1"],"introduced":["0"],"last_affected":[],"package":"mbedtls","purl":"pkg:rpm/opensuse/mbedtls\u0026distro=openSUSE%20Leap%2015.2","source":"openSUSE-SU-2021:0384-1"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2020-10931"},"products":["n/a"],"published":"2020-04-15","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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"An attacker with side-channel access can recover ECDSA private keys from Mbed TLS, compromising cryptographic security.","url":"https://insights.sbomify.com/CVE-2020-10932/"}
