It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-37200 in the wild and no public exploit code.\n\nAffected product: Schneider Electric EcoStruxure OPC UA Server Expert. 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-2023-37200/ (Markdown: https://insights.sbomify.com/CVE-2023-37200/index.md)","id":"CVE-2023-37200","markdown":"https://insights.sbomify.com/CVE-2023-37200/index.md","name":"CVE-2023-37200","record":{"aliases":["GHSA-mhjw-pxqp-cm9c"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"OPC UA Server Expert","requires_auth":"none","summary":"An attacker can exploit an XML External Entity vulnerability to read local files, requiring manual server restart for impact.","user_interaction":"required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"ecostruxure_opc_ua_server_expert","vendor":"se"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"A CWE-611: Improper Restriction of XML External Entity Reference vulnerability exists that\ncould cause loss of confidentiality when replacing a project file on the local filesystem and after\nmanual restart of the server.","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":"XML external entity in EcoStruxure OPC UA Server Expert","id":"CVE-2023-37200","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in Firefox","id":"CVE-2023-37201"},"packages":[],"prev":{"headline":"Code injection in StruxureWare Data Center Expert","id":"CVE-2023-37199"},"products":["EcoStruxure OPC UA Server Expert"],"published":"2023-07-12","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-07","vendors":["Schneider Electric"]},"summary":"An attacker can exploit an XML External Entity vulnerability to read local files, requiring manual server restart for impact.","url":"https://insights.sbomify.com/CVE-2023-37200/"}
