It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-7523 and fix it if it is affected.\n\nWhat it is: CVE-2020-7523 is a high-severity vulnerability in Schneider Electric Modbus Serial Driver (64 bits) versions prior to V3.20 IE 30, Schneider Electric Modbus Serial Driver (32 bits) versions prior to V2.20 IE 30, and Schneider Electric Modbus Driver Suite versions prior to V14.15.0.0, published on 31 Aug 2020. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-7523 in the wild and no public exploit code.\n\nAffected product: Schneider Electric Modbus Serial Driver (64 bits) versions prior to V3.20 IE 30, Schneider Electric Modbus Serial Driver (32 bits) versions prior to V2.20 IE 30, and Schneider Electric Modbus Driver Suite versions prior to V14.15.0.0. 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-2020-7523/ (Markdown: https://insights.sbomify.com/CVE-2020-7523/index.md)","id":"CVE-2020-7523","markdown":"https://insights.sbomify.com/CVE-2020-7523/index.md","name":"CVE-2020-7523","record":{"aliases":["GHSA-pxg4-q469-ggv7"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Modbus Serial Driver","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges by invoking the Schneider Electric Modbus Serial Driver service due to improper privilege management.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modbus_driver_suite","vendor":"schneider-electric"},{"product":"modbus_serial_driver","vendor":"schneider-electric"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Improper Privilege Management vulnerability exists in Schneider Electric Modbus Serial Driver (see security notification for versions) which could cause local privilege escalation when the Modbus Serial Driver service is invoked.
