An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-34563 exists.\n\nAffected product: Netgear R6250 Firmware. 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-2023-34563/ (Markdown: https://insights.sbomify.com/CVE-2023-34563/index.md)","id":"CVE-2023-34563","markdown":"https://insights.sbomify.com/CVE-2023-34563/index.md","name":"CVE-2023-34563","record":{"aliases":["GHSA-5jxp-5vrv-qmg9"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Netgear router firmware","requires_auth":"none","summary":"An authenticated attacker can exploit a buffer overflow in Netgear R6250 firmware to execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"r6250_firmware","vendor":"netgear"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"netgear R6250 Firmware Version 1.0.4.48 is vulnerable to Buffer Overflow after authentication.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2023-34563","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"netgear:r6250_firmware","products":["netgear:r6250_firmware"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2023-34565"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-34561"},"products":["n/a"],"published":"2023-06-20","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2023-33532","kev_date_added":null,"published":"2023-06-06"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-28373","kev_date_added":null,"published":"2020-11-09"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-18744","kev_date_added":null,"published":"2020-04-23"},{"cvss_score":7.4,"headline":"Misconfiguration in n/a","id":"CVE-2017-18741","kev_date_added":null,"published":"2020-04-23"},{"cvss_score":6.3,"headline":"Command injection in n/a","id":"CVE-2021-38519","kev_date_added":null,"published":"2021-08-11"}],"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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-12-09","vendors":["n/a"]},"summary":"An authenticated attacker can exploit a buffer overflow in Netgear R6250 firmware to execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2023-34563/"}
