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-2023-54400 exists.\n\nAffected product: Fumasoft Fumeng Cloud. 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-2023-54400/ (Markdown: https://insights.sbomify.com/CVE-2023-54400/index.md)","id":"CVE-2023-54400","markdown":"https://insights.sbomify.com/CVE-2023-54400/index.md","name":"CVE-2023-54400","record":{"aliases":["GHSA-39vr-225p-6ccc"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Fumeng Cloud","requires_auth":"none","summary":"Unauthenticated attackers can inject SQL via the getEmpByname endpoint to read and modify database contents in Fumeng Cloud.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"Fumasoft Fumeng Cloud contains a SQL injection vulnerability in the AjaxMethod.ashx endpoint that allows unauthenticated remote attackers to inject arbitrary SQL through the Name parameter of the getEmpByname action without any authentication.
