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-2023-54403 in the wild and no public exploit code.\n\nAffected product: Yonyou U8 CRM. 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-2023-54403/ (Markdown: https://insights.sbomify.com/CVE-2023-54403/index.md)","id":"CVE-2023-54403","markdown":"https://insights.sbomify.com/CVE-2023-54403/index.md","name":"CVE-2023-54403","record":{"aliases":["GHSA-8vgx-v6gm-mhxr"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Yonyou U8 CRM","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication and read arbitrary files, including credentials, via a path traversal vulnerability in Yonyou U8 CRM.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Yonyou U8 CRM before V16.5 and V18 contains an arbitrary file read vulnerability in /ajax/getemaildata.php that allows unauthenticated attackers to bypass authentication using the DontCheckLogin=1 parameter and read arbitrary files via an unvalidated filePath parameter.
