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-2021-34600 in the wild and no public exploit code.\n\nAffected product: Telenot Electronic GmbH CompasX. 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-2021-34600/ (Markdown: https://insights.sbomify.com/CVE-2021-34600/index.md)","id":"CVE-2021-34600","markdown":"https://insights.sbomify.com/CVE-2021-34600/index.md","name":"CVE-2021-34600","record":{"aliases":["GHSA-5f54-x7j7-36p3"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["security_bypass","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Access control system","requires_auth":"low_privilege","summary":"Weak AES key generation in Telenot CompasX allows attackers to predict NFC authorization keys, bypassing local access controls.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"compasx","vendor":"telenot"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-335","name":"Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG)"}],"description":"Telenot CompasX versions prior to 32.0 use a weak seed for random number generation leading to predictable AES keys used in the NFC tags used for local authorization of users.
