An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-7534 in the wild and no public exploit code.\n\nAffected product: 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). 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-2020-7534/ (Markdown: https://insights.sbomify.com/CVE-2020-7534/index.md)","id":"CVE-2020-7534","markdown":"https://insights.sbomify.com/CVE-2020-7534/index.md","name":"CVE-2020-7534","record":{"aliases":["GHSA-5g6x-5wq6-p6g5"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon PLC","requires_auth":"none","summary":"A CSRF vulnerability in Modicon PLC web servers allows attackers to leak sensitive data or perform unauthorized actions while a user is logged in.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"140cpu65_firmware","vendor":"schneider-electric"},{"product":"140noc78000_firmware","vendor":"schneider-electric"},{"product":"140noe77111_firmware","vendor":"schneider-electric"},{"product":"bmxnoc0401_firmware","vendor":"schneider-electric"},{"product":"bmxnoe01_firmware","vendor":"schneider-electric"},{"product":"bmxnor0200h_firmware","vendor":"schneider-electric"},{"product":"modicon_m340_bmxp342020_firmware","vendor":"schneider-electric"},{"product":"tsxety4103_firmware","vendor":"schneider-electric"},{"product":"tsxety5103_firmware","vendor":"schneider-electric"},{"product":"tsxp57_firmware","vendor":"schneider-electric"}],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A CWE-352: Cross-Site Request Forgery (CSRF) vulnerability exists on the web server used, that could cause a leak of sensitive data or unauthorized actions on the web server during the time the user is logged in.
