Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-42022 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC eaSie PCS 7 Skill Package. 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-2021-42022/ (Markdown: https://insights.sbomify.com/CVE-2021-42022/index.md)","id":"CVE-2021-42022","markdown":"https://insights.sbomify.com/CVE-2021-42022/index.md","name":"CVE-2021-42022","record":{"aliases":["GHSA-p462-h5xx-px29"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Siemens PCS 7 Skill Package","requires_auth":"low_privilege","summary":"Attackers can read critical files outside the restricted directory via path traversal in the file download function, which is disabled by default.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_easie_pcs_7_skill","vendor":"siemens"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A vulnerability has been identified in SIMATIC eaSie PCS 7 Skill Package (All versions \u003c V21.00 SP3).
