Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-5491 and fix it if it is affected.\n\nWhat it is: CVE-2023-5491 is a medium-severity vulnerability in Byzoro Smart S45F Multi-Service Secure Gateway Intelligent Management Platform, published on 10 Oct 2023. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-5491 exists.\n\nAffected product: Byzoro Smart S45F Multi-Service Secure Gateway Intelligent Management Platform. 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-2023-5491/ (Markdown: https://insights.sbomify.com/CVE-2023-5491/index.md)","id":"CVE-2023-5491","markdown":"https://insights.sbomify.com/CVE-2023-5491/index.md","name":"CVE-2023-5491","record":{"aliases":["GHSA-mg88-vr9f-rg8p"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Secure Gateway Platform","requires_auth":"low_privilege","summary":"Attackers can upload malicious files via the updatelib.php endpoint to execute arbitrary code on the Byzoro Smart S45F gateway.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"smart_s45f_firmware","vendor":"byzoro"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"A vulnerability, which was classified as critical, has been found in Byzoro Smart S45F Multi-Service Secure Gateway Intelligent Management Platform up to 20230928.
