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-2023-5909 in the wild and no public exploit code.\n\nAffected product: GE Gigital 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-2023-5909/ (Markdown: https://insights.sbomify.com/CVE-2023-5909/index.md)","id":"CVE-2023-5909","markdown":"https://insights.sbomify.com/CVE-2023-5909/index.md","name":"CVE-2023-5909","record":{"aliases":["GHSA-rw69-wr48-w7px"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Connectivity Server","requires_auth":"none","summary":"Improper certificate validation in PTC KEPServerEX allows unauthenticated users to connect, bypassing security controls in industrial environments.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"industrial_gateway_server","vendor":"ge"},{"product":"keepserverex","vendor":"ptc"},{"product":"opc-aggregator","vendor":"ptc"},{"product":"thingworx_industrial_connectivity","vendor":"ptc"},{"product":"thingworx_kepware_edge","vendor":"ptc"},{"product":"thingworx_kepware_server","vendor":"ptc"},{"product":"kepserver_enterprise","vendor":"rockwellautomation"},{"product":"top_server","vendor":"softwaretoolbox"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"},{"id":"CWE-297","name":"Improper Validation of Certificate with Host Mismatch"}],"description":"KEPServerEX does not properly validate certificates from clients which may allow unauthenticated users to connect.","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":"Improper Validation of Certificate with Host Mismatch in PTC KEPServerEx","id":"CVE-2023-5909","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"PopojiCMS Web Config install.php cross site scripting","id":"CVE-2023-5910"},"packages":[],"prev":{"headline":"Heap Based Buffer Overflow in PTC KEPServerEx","id":"CVE-2023-5908"},"products":["Industrial Gateway Server","KEPServer Enterprise","KEPServerEX","OPC-Aggregator","TOP Server","ThingWorx Industrial Connectivity","ThingWorx Kepware Edge","ThingWorx Kepware Server"],"published":"2023-11-30","related":[{"cvss_score":9.8,"headline":"Memory corruption in KEPServerEX","id":"CVE-2022-2825","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":9.8,"headline":"Memory corruption in PTC Kepware KEPServerEX; ThingWorx Industrial Connectivity; OPC-Aggregator; Rockwell Automation KEPServer Enterprise; GE Digital Industrial Gateway Server; Software Toolbox TOP Server","id":"CVE-2020-27265","kev_date_added":null,"published":"2021-01-13"},{"cvss_score":9.1,"headline":"Heap Based Buffer Overflow in PTC KEPServerEx","id":"CVE-2023-5908","kev_date_added":null,"published":"2023-11-30"},{"cvss_score":9.1,"headline":"Memory corruption in KEPServerEX","id":"CVE-2022-2848","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":9.1,"headline":"Memory corruption in GE Digital Industrial Gateway Server","id":"CVE-2020-27263","kev_date_added":null,"published":"2021-01-13"},{"cvss_score":9.1,"headline":"Memory corruption in GE Digital Industrial Gateway Server","id":"CVE-2020-27267","kev_date_added":null,"published":"2021-01-13"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-25","vendors":["GE Gigital","PTC","Rockwell Automation ","Software Toolbox"]},"summary":"Improper certificate validation in PTC KEPServerEX allows unauthenticated users to connect, bypassing security controls in industrial environments.","url":"https://insights.sbomify.com/CVE-2023-5909/"}
