An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-50763 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC CP 1542SP-1. 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-2023-50763/ (Markdown: https://insights.sbomify.com/CVE-2023-50763/index.md)","id":"CVE-2023-50763","markdown":"https://insights.sbomify.com/CVE-2023-50763/index.md","name":"CVE-2023-50763","record":{"aliases":["GHSA-2r3h-3xfx-74q9"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Siemens SIMATIC CP","requires_auth":"high_privilege","summary":"An authenticated remote attacker can cause a denial of service by importing crafted PKCS12 containers into the web server if PKCS12 import is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"A vulnerability has been identified in SIMATIC CP 1542SP-1 (6GK7542-6UX00-0XE0) (All versions \u003c V2.3), SIMATIC CP 1542SP-1 IRC (6GK7542-6VX00-0XE0) (All versions \u003c V2.3), SIMATIC CP 1543SP-1 (6GK7543-6WX00-0XE0) (All versions \u003c V2.3), SIPLUS ET 200SP CP 1542SP-1 IRC TX RAIL (6AG2542-6VX00-4XE0) (All versions \u003c V2.3), SIPLUS ET 200SP CP 1543SP-1 ISEC (6AG1543-6WX00-7XE0) (All versions \u003c V2.3), SIPLUS ET 200SP CP 1543SP-1 ISEC TX RAIL (6AG2543-6WX00-4XE0) (All versions \u003c V2.3), SIPLUS TIM 1531 IRC (6AG1543-1MX00-7XE0) (All versions \u003c V2.4.8), TIM 1531 IRC (6GK7543-1MX00-0XE0) (All versions \u003c V2.4.8).
