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-2021-31892 in the wild and no public exploit code.\n\nAffected product: Siemens SINUMERIK Analyse MyCondition. 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-2021-31892/ (Markdown: https://insights.sbomify.com/CVE-2021-31892/index.md)","id":"CVE-2021-31892","markdown":"https://insights.sbomify.com/CVE-2021-31892/index.md","name":"CVE-2021-31892","record":{"aliases":["GHSA-wr99-8g6h-68jx"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SINUMERIK software","requires_auth":"none","summary":"An attacker can perform a TLS man-in-the-middle attack due to missing server certificate validation in Siemens SINUMERIK software.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"sinumerik_analyse_mycondition_firmware","vendor":"siemens"},{"product":"sinumerik_analyze_myperformance_firmware","vendor":"siemens"},{"product":"sinumerik_integrate_client_firmware","vendor":"siemens"},{"product":"sinumerik_integrate_for_production_firmware","vendor":"siemens"},{"product":"sinumerik_manage_mymachines_firmware","vendor":"siemens"},{"product":"sinumerik_manage_myprograms_firmware","vendor":"siemens"},{"product":"sinumerik_manage_myresources_firmware","vendor":"siemens"},{"product":"sinumerik_manage_mytools_firmware","vendor":"siemens"},{"product":"sinumerik_operate_firmware","vendor":"siemens"},{"product":"sinumerik_optimize_myprogramming_firmware","vendor":"siemens"}],"cvss":{"score":7.4,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"A vulnerability has been identified in SINUMERIK Analyse MyCondition (All versions), SINUMERIK Analyze MyPerformance (All versions), SINUMERIK Analyze MyPerformance /OEE-Monitor (All versions), SINUMERIK Analyze MyPerformance /OEE-Tuning (All versions), SINUMERIK Integrate Client 02 (All versions \u003e= V02.00.12 \u003c 02.00.18), SINUMERIK Integrate Client 03 (All versions \u003e= V03.00.12 \u003c 03.00.18), SINUMERIK Integrate Client 04 (V04.00.02 and all versions \u003e= V04.00.15 \u003c 04.00.18), SINUMERIK Integrate for Production 4.1 (All versions \u003c V4.1 SP10 HF3), SINUMERIK Integrate for Production 5.1 (V5.1), SINUMERIK Manage MyMachines (All versions), SINUMERIK Manage MyMachines /Remote (All versions), SINUMERIK Manage MyMachines /Spindel Monitor (All versions), SINUMERIK Manage MyPrograms (All versions), SINUMERIK Manage MyResources /Programs (All versions), SINUMERIK Manage MyResources /Tools (All versions), SINUMERIK Manage MyTools (All versions), SINUMERIK Operate V4.8 (All versions \u003c V4.8 SP8), SINUMERIK Operate V4.93 (All versions \u003c V4.93 HF7), SINUMERIK Operate V4.94 (All versions \u003c V4.94 HF5), SINUMERIK Optimize MyProgramming /NX-Cam Editor (All versions).
