Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-7788 in the wild and no public exploit code.\n\nAffected product: Modicon Quantum with firmware versions prior to V2.40.. 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-2018-7788/ (Markdown: https://insights.sbomify.com/CVE-2018-7788/index.md)","id":"CVE-2018-7788","markdown":"https://insights.sbomify.com/CVE-2018-7788/index.md","name":"CVE-2018-7788","record":{"aliases":["GHSA-4pc3-f84w-r58f"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon Quantum PLC","requires_auth":"low_privilege","summary":"A denial of service vulnerability in Modicon Quantum PLCs allows attackers to disrupt operations via Telnet connections.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicon_quantum_firmware","vendor":"schneider-electric"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-255","name":null}],"description":"A CWE-255 Credentials Management vulnerability exists in Modicon Quantum with firmware versions prior to V2.40. which could cause a Denial Of Service when using a Telnet connection.","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 Modicon Quantum with firmware versions prior to V2.40.","id":"CVE-2018-7788","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Modicon M221, all references, all versions prior to firmware V1.6.2.0","id":"CVE-2018-7789"},"packages":[],"prev":{"headline":"Other in U.motion Builder","id":"CVE-2018-7787"},"products":["Modicon Quantum with firmware versions prior to V2.40."],"published":"2019-05-22","related":[{"cvss_score":9.1,"headline":"Missing authorization in Modicon Quantum - all firmware versions","id":"CVE-2019-6815","kev_date_added":null,"published":"2019-05-22"},{"cvss_score":9.1,"headline":"Code injection in Modicon Quantum - all firmware versions","id":"CVE-2019-6816","kev_date_added":null,"published":"2019-05-22"}],"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":["n/a"]},"summary":"A denial of service vulnerability in Modicon Quantum PLCs allows attackers to disrupt operations via Telnet connections.","url":"https://insights.sbomify.com/CVE-2018-7788/"}
