Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2020-28396 and fix it if it is affected.\n\nWhat it is: CVE-2020-28396 is a high-severity vulnerability in Siemens SICAM A8000 CP-8000, published on 14 Dec 2020. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-28396 in the wild and no public exploit code.\n\nAffected product: Siemens SICAM A8000 CP-8000. 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-2020-28396/ (Markdown: https://insights.sbomify.com/CVE-2020-28396/index.md)","id":"CVE-2020-28396","markdown":"https://insights.sbomify.com/CVE-2020-28396/index.md","name":"CVE-2020-28396","record":{"aliases":["GHSA-gw3g-78vp-6j8f"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SICAM A8000","requires_auth":"low_privilege","summary":"An attacker in a privileged position can decrypt communications due to insecure cipher usage, compromising data confidentiality and integrity.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"sicam_a8000_cp-8000_firmware","vendor":"siemens"},{"product":"sicam_a8000_cp-8021_firmware","vendor":"siemens"},{"product":"sicam_a8000_cp-8022_firmware","vendor":"siemens"}],"cvss":{"score":7.3,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"},{"id":"CWE-693","name":"Protection Mechanism Failure"}],"description":"A vulnerability has been identified in SICAM A8000 CP-8000 (All versions \u003c V16), SICAM A8000 CP-8021 (All versions \u003c V16), SICAM A8000 CP-8022 (All versions \u003c V16).
