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-2018-7758 and fix it if it is affected.\n\nWhat it is: CVE-2018-7758 is a medium-severity denial of service vulnerability in Schneider Electric SE MiCOM P540D Range with Legacy Ethernet Board, published on 18 Apr 2018. 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-2018-7758 in the wild and no public exploit code.\n\nAffected product: Schneider Electric SE MiCOM P540D Range with Legacy Ethernet Board. 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-2018-7758/ (Markdown: https://insights.sbomify.com/CVE-2018-7758/index.md)","id":"CVE-2018-7758","markdown":"https://insights.sbomify.com/CVE-2018-7758/index.md","name":"CVE-2018-7758","record":{"aliases":["GHSA-w8w3-m5jx-qwwr"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Schneider Electric relay","requires_auth":"none","summary":"An attacker can cause loss of network communication in Schneider Electric MiCOM relays by exploiting TCP/IP session handling flaws on port 20000.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"micom_p141_firmware","vendor":"schneider-electric"},{"product":"micom_p142_firmware","vendor":"schneider-electric"},{"product":"micom_p143_firmware","vendor":"schneider-electric"},{"product":"micom_p145_firmware","vendor":"schneider-electric"},{"product":"micom_p441_firmware","vendor":"schneider-electric"},{"product":"micom_p442_firmware","vendor":"schneider-electric"},{"product":"micom_p443_firmware","vendor":"schneider-electric"},{"product":"micom_p444_firmware","vendor":"schneider-electric"},{"product":"micom_p445_firmware","vendor":"schneider-electric"},{"product":"micom_p446_firmware","vendor":"schneider-electric"},{"product":"micom_p541_firmware","vendor":"schneider-electric"},{"product":"micom_p542_firmware","vendor":"schneider-electric"},{"product":"micom_p543_firmware","vendor":"schneider-electric"},{"product":"micom_p544_firmware","vendor":"schneider-electric"},{"product":"micom_p545_firmware","vendor":"schneider-electric"},{"product":"micom_p546_firmware","vendor":"schneider-electric"},{"product":"micom_p642_firmware","vendor":"schneider-electric"},{"product":"micom_p643_firmware","vendor":"schneider-electric"},{"product":"micom_p645_firmware","vendor":"schneider-electric"},{"product":"micom_p746_firmware","vendor":"schneider-electric"},{"product":"micom_p841a_firmware","vendor":"schneider-electric"},{"product":"micom_p841b_firmware","vendor":"schneider-electric"},{"product":"micom_p849_firmware","vendor":"schneider-electric"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"A denial of service vulnerability exists in Schneider Electric's MiCOM Px4x (P540 range excluded) with legacy Ethernet board, MiCOM P540D Range with Legacy Ethernet Board, and MiCOM Px4x Rejuvenated could lose network communication in case of TCP/IP open requests on port 20000 (DNP3oE) if an older TCI/IP session is still open with identical IP address and port number.","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 MiCOM P540D Range with Legacy Ethernet Board","id":"CVE-2018-7758","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in Modicon M340, Modicon Premium, Modicon Quantum, BMXNOR0200","id":"CVE-2018-7759"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2018-7757"},"products":["MiCOM P540D Range with Legacy Ethernet Board"],"published":"2018-04-18","related":[],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Schneider Electric SE"]},"summary":"An attacker can cause loss of network communication in Schneider Electric MiCOM relays by exploiting TCP/IP session handling flaws on port 20000.","url":"https://insights.sbomify.com/CVE-2018-7758/"}
