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-2021-3565 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2021-3565/ (Markdown: https://insights.sbomify.com/CVE-2021-3565/index.md)","id":"CVE-2021-3565","markdown":"https://insights.sbomify.com/CVE-2021-3565/index.md","name":"CVE-2021-3565","record":{"aliases":["ALSA-2021:4413","AZL-6923","DEBIAN-CVE-2021-3565","GHSA-jxhq-r9c5-f85p","MGASA-2021-0353","OESA-2021-1384","RHSA-2021:4413","RLSA-2021:4413","SUSE-SU-2021:1998-1","SUSE-SU-2021:1999-1","UBUNTU-CVE-2021-3565","openSUSE-SU-2021:0934-1","openSUSE-SU-2021:1998-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"TPM2 tools","requires_auth":"none","summary":"A fixed AES key in tpm2-tools allows MITM attackers to unwrap inner data and reveal imported keys, compromising confidentiality.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"tpm2-tools","vendor":"tpm2-tools_project"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"},{"id":"CWE-665","name":"Improper Initialization"}],"description":"A flaw was found in tpm2-tools in versions before 5.1.1 and before 4.3.2. tpm2_import used a fixed AES key for the inner wrapper, potentially allowing a MITM attacker to unwrap the inner portion and reveal the key being imported.
