It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-43099 in the wild and no public exploit code.\n\nAffected product: AutomationDirect DirectLogic H2-DM1E. 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-2024-43099/ (Markdown: https://insights.sbomify.com/CVE-2024-43099/index.md)","id":"CVE-2024-43099","markdown":"https://insights.sbomify.com/CVE-2024-43099/index.md","name":"CVE-2024-43099","record":{"aliases":["GHSA-xqww-5c9g-v62q"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PLC controller","requires_auth":"none","summary":"An attacker can hijack authenticated sessions by capturing session keys and spoofing network addresses to inject traffic into PLC communications.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"}],"description":"The session hijacking attack targets the application layer's control mechanism, which manages authenticated sessions between a host PC and a PLC. During such sessions, a session key is utilized to maintain security. However, if an attacker captures this session key, they can inject traffic into an ongoing authenticated session. To successfully achieve this, the attacker also needs to spoof both the IP address and MAC address of the originating host which is typical of a session-based attack.","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":"AutomationDirect DirectLogic H2-DM1E Authentication Bypass by Capture-replay","id":"CVE-2024-43099","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Intel(R) Data Center GPU Flex Series for Windows driver software","id":"CVE-2024-43101"},"packages":[],"prev":{"headline":"i3c: Use i3cdev-\u003edesc-\u003einfo instead of calling i3c_device_get_info() to avoid deadlock","id":"CVE-2024-43098"},"products":["DirectLogic H2-DM1E"],"published":"2024-09-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-13","vendors":["AutomationDirect"]},"summary":"An attacker can hijack authenticated sessions by capturing session keys and spoofing network addresses to inject traffic into PLC communications.","url":"https://insights.sbomify.com/CVE-2024-43099/"}
