An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-1892 and fix it if it is affected.\n\nWhat it is: CVE-2019-1892 is a high-severity memory corruption vulnerability in Cisco Small Business 300 Series Managed Switches, published on 6 Jul 2019. 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-2019-1892 in the wild and no public exploit code.\n\nAffected product: Cisco Small Business 300 Series Managed Switches. 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-2019-1892/ (Markdown: https://insights.sbomify.com/CVE-2019-1892/index.md)","id":"CVE-2019-1892","markdown":"https://insights.sbomify.com/CVE-2019-1892/index.md","name":"CVE-2019-1892","record":{"aliases":["GHSA-4r8c-mv24-j28q"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Small Business Switch","requires_auth":"none","summary":"Unauthenticated remote attackers can cause a denial of service on Cisco Small Business switches by sending malformed HTTPS packets to the management interface.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"esw2-350g52dc_firmware","vendor":"cisco"},{"product":"esw2-550x48dc_firmware","vendor":"cisco"},{"product":"sf200-24_firmware","vendor":"cisco"},{"product":"sf200-24p_firmware","vendor":"cisco"},{"product":"sf200-48_firmware","vendor":"cisco"},{"product":"sf200-48p_firmware","vendor":"cisco"},{"product":"sf300-08_firmware","vendor":"cisco"},{"product":"sf300-24_firmware","vendor":"cisco"},{"product":"sf300-24mp_firmware","vendor":"cisco"},{"product":"sf300-24p_firmware","vendor":"cisco"},{"product":"sf300-24pp_firmware","vendor":"cisco"},{"product":"sf300-48_firmware","vendor":"cisco"},{"product":"sf300-48p_firmware","vendor":"cisco"},{"product":"sf300-48pp_firmware","vendor":"cisco"},{"product":"sf302-08_firmware","vendor":"cisco"},{"product":"sf302-08mp_firmware","vendor":"cisco"},{"product":"sf302-08mpp_firmware","vendor":"cisco"},{"product":"sf302-08p_firmware","vendor":"cisco"},{"product":"sf302-08pp_firmware","vendor":"cisco"},{"product":"sf500-24_firmware","vendor":"cisco"},{"product":"sf500-24mp_firmware","vendor":"cisco"},{"product":"sf500-24p_firmware","vendor":"cisco"},{"product":"sf500-48_firmware","vendor":"cisco"},{"product":"sf500-48mp_firmware","vendor":"cisco"},{"product":"sf500-48p_firmware","vendor":"cisco"},{"product":"sg200-18_firmware","vendor":"cisco"},{"product":"sg200-26_firmware","vendor":"cisco"},{"product":"sg200-26p_firmware","vendor":"cisco"},{"product":"sg200-50_firmware","vendor":"cisco"},{"product":"sg200-50p_firmware","vendor":"cisco"},{"product":"sg300-10_firmware","vendor":"cisco"},{"product":"sg300-10mp_firmware","vendor":"cisco"},{"product":"sg300-10mpp_firmware","vendor":"cisco"},{"product":"sg300-10p_firmware","vendor":"cisco"},{"product":"sg300-10pp_firmware","vendor":"cisco"},{"product":"sg300-10sfp_firmware","vendor":"cisco"},{"product":"sg300-20_firmware","vendor":"cisco"},{"product":"sg300-28_firmware","vendor":"cisco"},{"product":"sg300-28mp_firmware","vendor":"cisco"},{"product":"sg300-28p_firmware","vendor":"cisco"},{"product":"sg300-28pp_firmware","vendor":"cisco"},{"product":"sg300-28sfp_firmware","vendor":"cisco"},{"product":"sg300-52_firmware","vendor":"cisco"},{"product":"sg300-52mp_firmware","vendor":"cisco"},{"product":"sg300-52p_firmware","vendor":"cisco"},{"product":"sg500-28_firmware","vendor":"cisco"},{"product":"sg500-28mpp_firmware","vendor":"cisco"},{"product":"sg500-28p_firmware","vendor":"cisco"},{"product":"sg500-52_firmware","vendor":"cisco"},{"product":"sg500-52mp_firmware","vendor":"cisco"},{"product":"sg500-52p_firmware","vendor":"cisco"},{"product":"sg500x-24_firmware","vendor":"cisco"},{"product":"sg500x-48_firmware","vendor":"cisco"},{"product":"sg500x-48mp_firmware","vendor":"cisco"},{"product":"sg500x-48p_firmware","vendor":"cisco"},{"product":"sg500x24mpp_firmware","vendor":"cisco"},{"product":"sg500xg8f8t_firmware","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in the Secure Sockets Layer (SSL) input packet processor of Cisco Small Business 200, 300, and 500 Series Managed Switches could allow an unauthenticated, remote attacker to cause a memory corruption on an affected device.
