Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-25620 and fix it if it is affected.\n\nWhat it is: CVE-2023-25620 is a medium-severity denial of service vulnerability in Schneider Electric Legacy Modicon Premium CPUs (TSXP57*), published on 19 Apr 2023. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-25620 in the wild and no public exploit code.\n\nAffected product: Schneider Electric Legacy Modicon Premium CPUs (TSXP57*). 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-2023-25620/ (Markdown: https://insights.sbomify.com/CVE-2023-25620/index.md)","id":"CVE-2023-25620","markdown":"https://insights.sbomify.com/CVE-2023-25620/index.md","name":"CVE-2023-25620","record":{"aliases":["GHSA-jp8p-mv2j-qxc2"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Schneider Modicon PLC","requires_auth":"low_privilege","summary":"An authenticated user can cause denial of service on Schneider Modicon PLCs by loading a malicious project file.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"140cpu65_firmware","vendor":"schneider-electric"},{"product":"bmeh58s_firmware","vendor":"schneider-electric"},{"product":"bmep58s_firmware","vendor":"schneider-electric"},{"product":"modicon_m340_firmware","vendor":"schneider-electric"},{"product":"modicon_m580_firmware","vendor":"schneider-electric"},{"product":"modicon_mc80_firmware","vendor":"schneider-electric"},{"product":"modicon_momentum_unity_m1e_processor_firmware","vendor":"schneider-electric"},{"product":"tsxp57_firmware","vendor":"schneider-electric"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","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-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"A CWE-754: Improper Check for Unusual or Exceptional Conditions vulnerability exists that\ncould cause denial of service of the controller when a malicious project file is loaded onto the\ncontroller by an authenticated user.","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 Legacy Modicon Premium CPUs (TSXP57*)","id":"CVE-2023-25620","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Sling does not allow to handle i18n content in a secure way","id":"CVE-2023-25621"},"packages":[],"prev":{"headline":"Denial of service in Legacy Modicon Premium CPUs (TSXP57*)","id":"CVE-2023-25619"},"products":["Legacy Modicon Premium CPUs (TSXP57*)","Legacy Modicon Quantum (140CPU65*)","Modicon M340 CPU (part numbers BMXP34*) ","Modicon M580 CPU (part numbers BMEP* and BMEH*)","Modicon M580 CPU Safety (part numbers BMEP58*S and BMEH58*S)","Modicon MC80 (BMKC80)","Modicon Momentum Unity M1E Processor (171CBU*)"],"published":"2023-04-19","related":[{"cvss_score":7.1,"headline":"Cross-site request forgery in Modicon M340 CPUs: BMXP34 (All Versions), Modicon Quantum CPUs with integrated Ethernet (Copro): 140CPU65 (All Versions), Modicon Premium CPUs with integrated Ethernet (Copro): TSXP57 (All Versions), Modicon M340 ethernet modules: (BMXNOC0401, BMXNOE01, BMXNOR0200H) (All Versions), Modicon Quantum and Premium factory cast communication modules: (140NOE77111, 140NOC78*00, TSXETY5103, TSXETY4103)","id":"CVE-2020-7534","kev_date_added":null,"published":"2022-02-04"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-05","vendors":["Schneider Electric"]},"summary":"An authenticated user can cause denial of service on Schneider Modicon PLCs by loading a malicious project file.","url":"https://insights.sbomify.com/CVE-2023-25620/"}
