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-2023-5768 in the wild and no public exploit code.\n\nAffected product: Hitachi Energy RTU500 series. 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-2023-5768/ (Markdown: https://insights.sbomify.com/CVE-2023-5768/index.md)","id":"CVE-2023-5768","markdown":"https://insights.sbomify.com/CVE-2023-5768/index.md","name":"CVE-2023-5768","record":{"aliases":["GHSA-gv34-7cg2-7vfg"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"RTU500 series","requires_auth":"none","summary":"An attacker can cause a denial of service on the communication link of Hitachi Energy RTU500 series devices by sending malformed APDU frames.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Hitachi Energy","cpe":[{"product":"rtu520_firmware","vendor":"hitachienergy"},{"product":"rtu530_firmware","vendor":"hitachienergy"},{"product":"rtu540_firmware","vendor":"hitachienergy"},{"product":"rtu560_firmware","vendor":"hitachienergy"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A vulnerability exists in the HCI IEC 60870-5-104 that affects the RTU500 series product versions listed below. \nIncomplete or wrong received APDU frame layout may \ncause blocking on link layer.
