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-2023-51391 in the wild and no public exploit code.\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-2023-51391/ (Markdown: https://insights.sbomify.com/CVE-2023-51391/index.md)","id":"CVE-2023-51391","markdown":"https://insights.sbomify.com/CVE-2023-51391/index.md","name":"CVE-2023-51391","record":{"aliases":["GHSA-j435-3f42-ww7p"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Micrium OS HTTP Server","requires_auth":"none","summary":"An attacker can crash an IoT device by sending malformed HTTP headers to the Micrium OS Network HTTP Server, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[],"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-476","name":"NULL Pointer Dereference"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A bug in Micrium OS Network HTTP Server permits an invalid pointer dereference during header processing - potentially allowing a device crash and Denial of Service.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Micrium OS Network uC-HTTP server header parsing invalid pointer dereference vulnerability","id":"CVE-2023-51391","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Silicon Labs EFR32xxx parts with classic key storage do not use hardware accelerated AES-CCM","id":"CVE-2023-51392"},"packages":[],"prev":{"headline":"Information Disclosure Vulnerability in Journalpump","id":"CVE-2023-51390"},"products":[],"published":"2024-04-16","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["silabs.com"]},"summary":"An attacker can crash an IoT device by sending malformed HTTP headers to the Micrium OS Network HTTP Server, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2023-51391/"}
