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-2022-2502 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-2022-2502/ (Markdown: https://insights.sbomify.com/CVE-2022-2502/index.md)","id":"CVE-2022-2502","markdown":"https://insights.sbomify.com/CVE-2022-2502/index.md","name":"CVE-2022-2502","record":{"aliases":["GHSA-45rh-q5fv-wf42"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"RTU500 series","requires_auth":"none","summary":"An attacker can cause a denial of service by sending a crafted message to the RTU500, triggering a buffer overflow and reboot.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Hitachi Energy","cpe":[{"product":"rtu500_firmware","vendor":"hitachienergy"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability exists in the HCI IEC 60870-5-104 function included in certain versions of the RTU500 series product. The vulnerability can only be exploited, if the HCI 60870-5-104 is configured with support for IEC 62351-5 and the CMU contains the license feature ‘Advanced security’ which must be ordered separately. If these preconditions are fulfilled, an attacker could exploit the vulnerability by sending a specially crafted message to the RTU500, causing the targeted RTU500 CMU to reboot. The vulnerability is caused by a missing input data validation which eventually if exploited causes an internal buffer to overflow in the HCI IEC 60870-5-104 function.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in RTU500 series","id":"CVE-2022-2502","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Linux Kernel LoadPin bypass via dm-verity table reload","id":"CVE-2022-2503"},"packages":[],"prev":{"headline":"Security feature bypass in GitLab","id":"CVE-2022-2501"},"products":["RTU500 series"],"published":"2023-07-26","related":[{"cvss_score":7.5,"headline":"Memory corruption in RTU500 series","id":"CVE-2022-4608","kev_date_added":null,"published":"2023-07-26"},{"cvss_score":7.5,"headline":"Specially Crafted IEC 60870-5-104 Packet Vulnerability in RTU500 series","id":"CVE-2021-35533","kev_date_added":null,"published":"2021-11-26"},{"cvss_score":5.9,"headline":"Memory corruption in RTU500 series CMU Firmware","id":"CVE-2023-6711","kev_date_added":null,"published":"2023-12-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-05","vendors":["Hitachi Energy"]},"summary":"An attacker can cause a denial of service by sending a crafted message to the RTU500, triggering a buffer overflow and reboot.","url":"https://insights.sbomify.com/CVE-2022-2502/"}
