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-2023-27857 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation ThinManager ThinServer. 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-2023-27857/ (Markdown: https://insights.sbomify.com/CVE-2023-27857/index.md)","id":"CVE-2023-27857","markdown":"https://insights.sbomify.com/CVE-2023-27857/index.md","name":"CVE-2023-27857","record":{"aliases":["GHSA-pr5c-7q57-fp6g"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ThinManager ThinServer","requires_auth":"none","summary":"An unauthenticated remote attacker can crash the ThinServer application via a heap-based buffer over-read, causing a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Rockwell","cpe":[{"product":"thinmanager","vendor":"rockwellautomation"}],"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-125","name":"Out-of-bounds Read"}],"description":"In affected versions, a heap-based buffer over-read condition occurs when the message field indicates more data than is present in the message field\n\n in Rockwell Automation's ThinManager ThinServer.  An unauthenticated remote attacker can exploit this vulnerability to crash ThinServer.exe due to a read access violation.","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":"Rockwell Automation ThinManager ThinServer Heap-Based Buffer Overflow","id":"CVE-2023-27857","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Rockwell Automation Arena® Simulation Uninitialized Pointer Vulnerability","id":"CVE-2023-27858"},"packages":[],"prev":{"headline":"Rockwell Automation ThinManager ThinServer Path Traversal Download","id":"CVE-2023-27856"},"products":["ThinManager ThinServer"],"published":"2023-03-22","related":[{"cvss_score":9.8,"headline":"Rockwell Automation ThinManager ThinServer Path Traversal Upload","id":"CVE-2023-27855","kev_date_added":null,"published":"2023-03-21"},{"cvss_score":9.3,"headline":"Rockwell Automation FactoryTalk ThinManager Authentication Vulnerability","id":"CVE-2024-10386","kev_date_added":null,"published":"2024-10-25"},{"cvss_score":9.3,"headline":"Rockwell Automation ThinManager® ThinServer™ Improper Input Validation Vulnerability","id":"CVE-2024-5988","kev_date_added":null,"published":"2024-06-25"},{"cvss_score":9.3,"headline":"Rockwell Automation ThinManager® ThinServer™ Improper Input Validation Vulnerability","id":"CVE-2024-5989","kev_date_added":null,"published":"2024-06-25"},{"cvss_score":8.7,"headline":"Rockwell Automation FactoryTalk ThinManager Denial-of-Service Vulnerability","id":"CVE-2024-10387","kev_date_added":null,"published":"2024-10-25"},{"cvss_score":8.7,"headline":"ThinManager® ThinServer™ Improper Input Validation Vulnerability","id":"CVE-2024-5990","kev_date_added":null,"published":"2024-06-25"},{"cvss_score":8.6,"headline":"Rockwell Automation ThinManager® Server-Side Request Forgery Vulnerability","id":"CVE-2025-9065","kev_date_added":null,"published":"2025-09-09"}],"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":"partial"},"state":"PUBLISHED","updated":"2024-10-21","vendors":["Rockwell Automation"]},"summary":"An unauthenticated remote attacker can crash the ThinServer application via a heap-based buffer over-read, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2023-27857/"}
