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-2020-27267 in the wild and no public exploit code.\n\nAffected product: GE Digital Industrial Gateway Server. 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-2020-27267/ (Markdown: https://insights.sbomify.com/CVE-2020-27267/index.md)","id":"CVE-2020-27267","markdown":"https://insights.sbomify.com/CVE-2020-27267/index.md","name":"CVE-2020-27267","record":{"aliases":["GHSA-mr5h-jvqg-8jg8"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Connectivity Server","requires_auth":"none","summary":"Attackers can crash the server and potentially leak data by sending a crafted OPC UA message to vulnerable industrial connectivity products.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"industrial_gateway_server","vendor":"ge"},{"product":"kepware_kepserverex","vendor":"ptc"},{"product":"opc-aggregator","vendor":"ptc"},{"product":"thingworx_industrial_connectivity","vendor":"ptc"},{"product":"thingworx_kepware_server","vendor":"ptc"},{"product":"kepserver_enterprise","vendor":"rockwellautomation"},{"product":"top_server","vendor":"softwaretoolbox"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-416","name":"Use After Free"}],"description":"KEPServerEX v6.0 to v6.9, ThingWorx Kepware Server v6.8 and v6.9, ThingWorx Industrial Connectivity (all versions), OPC-Aggregator (all versions), Rockwell Automation KEPServer Enterprise, GE Digital Industrial Gateway Server v7.68.804 and v7.66, and Software Toolbox TOP Server all 6.x versions, are vulnerable to a heap-based buffer overflow.
