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-2020-13645 in the wild and no public exploit code.\n\nAffected product: Broadcom Fabric Operating System. 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-2020-13645/ (Markdown: https://insights.sbomify.com/CVE-2020-13645/index.md)","id":"CVE-2020-13645","markdown":"https://insights.sbomify.com/CVE-2020-13645/index.md","name":"CVE-2020-13645","record":{"aliases":["AZL-6440","CLEANSTART-2024-CH43456","DEBIAN-CVE-2020-13645","GHSA-p43h-5x4h-9pp7","MGASA-2020-0314","SUSE-SU-2021:3944-1","SUSE-SU-2021:3997-1","SUSE-SU-2021:4004-1","UBUNTU-CVE-2020-13645","USN-4405-1","openSUSE-SU-2021:1094-1","openSUSE-SU-2021:1554-1","openSUSE-SU-2021:3944-1","openSUSE-SU-2024:10790-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"GNOME glib-networking","requires_auth":"none","summary":"Applications using glib-networking may accept invalid TLS certificates if server identity is not specified, allowing man-in-the-middle attacks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fabric_operating_system","vendor":"broadcom"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"fedora","vendor":"fedoraproject"},{"product":"balsa","vendor":"gnome"},{"product":"glib-networking","vendor":"gnome"},{"product":"cloud_backup","vendor":"netapp"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server's TLS certificate if the application fails to specify the expected server identity.
