An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-31176 and fix it if it is affected.\n\nWhat it is: CVE-2023-31176 is a high-severity authentication bypass vulnerability in Schweitzer Engineering Laboratories SEL-451, published on 30 Nov 2023. 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-2023-31176 in the wild and no public exploit code.\n\nAffected product: Schweitzer Engineering Laboratories SEL-451. 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-2023-31176/ (Markdown: https://insights.sbomify.com/CVE-2023-31176/index.md)","id":"CVE-2023-31176","markdown":"https://insights.sbomify.com/CVE-2023-31176/index.md","name":"CVE-2023-31176","record":{"aliases":["GHSA-437p-76r5-9789"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SEL-451 relay","requires_auth":"none","summary":"An attacker can brute-force session tokens to bypass authentication on SEL-451 devices, gaining unauthorized access to critical infrastructure.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SEL","cpe":[{"product":"sel-451_firmware","vendor":"selinc"}],"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:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-331","name":"Insufficient Entropy"}],"description":"An Insufficient Entropy vulnerability in the Schweitzer Engineering Laboratories SEL-451 could allow an unauthenticated remote attacker to brute-force session tokens and bypass authentication. \n\nSee product Instruction Manual Appendix A dated 20230830 for more details.","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":"Insufficient entropy vulnerability could lead to authentication bypass","id":"CVE-2023-31176","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Improper neutralizataion of input could lead to execution of arbitrary code","id":"CVE-2023-31177"},"packages":[],"prev":{"headline":"Execution with Unnecessary Privileges","id":"CVE-2023-31175"},"products":["SEL-451"],"published":"2023-11-30","related":[{"cvss_score":6.5,"headline":"Improper authentication could lead to session hijacking","id":"CVE-2023-34388","kev_date_added":null,"published":"2023-11-30"},{"cvss_score":4.5,"headline":"Allocation of resources without limits could lead to denial of service","id":"CVE-2023-34389","kev_date_added":null,"published":"2023-11-30"},{"cvss_score":4.5,"headline":"Improper input validation could lead to denial of service","id":"CVE-2023-34390","kev_date_added":null,"published":"2023-11-30"},{"cvss_score":4.3,"headline":"Improper neutralizataion of input could lead to execution of arbitrary code","id":"CVE-2023-31177","kev_date_added":null,"published":"2023-11-30"}],"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":"2024-10-16","vendors":["Schweitzer Engineering Laboratories"]},"summary":"An attacker can brute-force session tokens to bypass authentication on SEL-451 devices, gaining unauthorized access to critical infrastructure.","url":"https://insights.sbomify.com/CVE-2023-31176/"}
