An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-4855 in the wild and no public exploit code.\n\nAffected product: Siemens AG SICLOCK TC100, SICLOCK TC400. 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-2018-4855/ (Markdown: https://insights.sbomify.com/CVE-2018-4855/index.md)","id":"CVE-2018-4855","markdown":"https://insights.sbomify.com/CVE-2018-4855/index.md","name":"CVE-2018-4855","record":{"aliases":["GHSA-5879-3vjc-222g"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"SICLOCK time server","requires_auth":"none","summary":"Attackers with privileged access can obtain passwords from unencrypted storage or network transmission in Siemens SICLOCK devices.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"siclock_tc100_firmware","vendor":"siemens"},{"product":"siclock_tc400_firmware","vendor":"siemens"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-311","name":"Missing Encryption of Sensitive Data"}],"description":"A vulnerability has been identified in SICLOCK TC100 (All versions) and SICLOCK TC400 (All versions).
