An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-33138 and fix it if it is affected.\n\nWhat it is: CVE-2022-33138 is a high-severity missing authorization vulnerability in Siemens SIMATIC MV540 H, published on 12 Jul 2022. 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-2022-33138 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC MV540 H. 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-2022-33138/ (Markdown: https://insights.sbomify.com/CVE-2022-33138/index.md)","id":"CVE-2022-33138","markdown":"https://insights.sbomify.com/CVE-2022-33138/index.md","name":"CVE-2022-33138","record":{"aliases":["GHSA-c482-89c3-ccmp"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens vision sensor","requires_auth":"none","summary":"Unauthenticated remote attackers can read and download data from affected Siemens SIMATIC vision sensors due to missing authentication on web API endpoints.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_mv540_h_firmware","vendor":"siemens"},{"product":"simatic_mv540_s_firmware","vendor":"siemens"},{"product":"simatic_mv550_h_firmware","vendor":"siemens"},{"product":"simatic_mv550_s_firmware","vendor":"siemens"},{"product":"simatic_mv560_u_firmware","vendor":"siemens"},{"product":"simatic_mv560_x_firmware","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"A vulnerability has been identified in SIMATIC MV540 H (All versions \u003c V3.3), SIMATIC MV540 S (All versions \u003c V3.3), SIMATIC MV550 H (All versions \u003c V3.3), SIMATIC MV550 S (All versions \u003c V3.3), SIMATIC MV560 U (All versions \u003c V3.3), SIMATIC MV560 X (All versions \u003c V3.3).
