An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-27265 and fix it if it is affected.\n\nWhat it is: CVE-2020-27265 is a critical memory corruption vulnerability in PTC Kepware KEPServerEX;  ThingWorx Industrial Connectivity; OPC-Aggregator; Rockwell Automation KEPServer Enterprise; GE Digital Industrial Gateway Server; Software Toolbox TOP Server, published on 13 Jan 2021. 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-2020-27265 in the wild and no public exploit code.\n\nAffected product: PTC Kepware KEPServerEX;  ThingWorx Industrial Connectivity; OPC-Aggregator; Rockwell Automation KEPServer Enterprise; GE Digital Industrial Gateway Server; Software Toolbox TOP 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-2020-27265/ (Markdown: https://insights.sbomify.com/CVE-2020-27265/index.md)","id":"CVE-2020-27265","markdown":"https://insights.sbomify.com/CVE-2020-27265/index.md","name":"CVE-2020-27265","record":{"aliases":["GHSA-355x-g6q7-4c7g"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial connectivity server","requires_auth":"none","summary":"Attackers can execute arbitrary code or crash the server 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":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"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, Software Toolbox TOP Server: All 6.x versions are vulnerable to a stack-based buffer overflow.
