An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-3825 in the wild and no public exploit code.\n\nAffected product: PTC KEPServerEX. 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-2023-3825/ (Markdown: https://insights.sbomify.com/CVE-2023-3825/index.md)","id":"CVE-2023-3825","markdown":"https://insights.sbomify.com/CVE-2023-3825/index.md","name":"CVE-2023-3825","record":{"aliases":["GHSA-m3jq-gg7x-47cq"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial connectivity server","requires_auth":"none","summary":"Attackers can crash KEPServerEX by sending malicious OPC UA messages causing stack overflow, impacting industrial connectivity availability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"kepserverex","vendor":"kepware"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"PTC’s KEPServerEX Versions 6.0 to 6.14.263 are vulnerable to being made to read a recursively defined object that leads to uncontrolled resource consumption.
