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-2020-24683 in the wild and no public exploit code.\n\nAffected product: ABB Ability™ Symphony® Plus Operations. 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-2020-24683/ (Markdown: https://insights.sbomify.com/CVE-2020-24683/index.md)","id":"CVE-2020-24683","markdown":"https://insights.sbomify.com/CVE-2020-24683/index.md","name":"CVE-2020-24683","record":{"aliases":["GHSA-r3q7-7pwq-hqq8"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"ABB Symphony Plus","requires_auth":"none","summary":"Attackers can bypass authentication in ABB Symphony Plus Operations by exploiting client-side validation, allowing unauthorized server connections.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ABB","cpe":[{"product":"symphony_\\+_historian","vendor":"abb"},{"product":"symphony_\\+_operations","vendor":"abb"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"},{"id":"CWE-602","name":"Client-Side Enforcement of Server-Side Security"},{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"}],"description":"The affected versions of S+ Operations (version 2.1 SP1 and earlier) used an approach for user authentication which relies on validation at the client node (client-side authentication).
