E-office, published on 30 Apr 2026. 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-2022-50993 exists.\n\nAffected product: Weaver Network Co., Ltd. E-office. 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-2022-50993/ (Markdown: https://insights.sbomify.com/CVE-2022-50993/index.md)","id":"CVE-2022-50993","markdown":"https://insights.sbomify.com/CVE-2022-50993/index.md","name":"CVE-2022-50993","record":{"aliases":["GHSA-g99j-cq2q-3xrv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"E-office web application","requires_auth":"none","summary":"Unauthenticated attackers can upload malicious PHP files to achieve remote code execution on Weaver E-office servers.","user_interaction":"not_required","vuln_class":"file_upload"},"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-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Weaver (Fanwei) E-office versions prior to 10.0_20221201 contain an unauthenticated arbitrary file upload vulnerability in the OfficeServer.php endpoint that allows remote attackers to upload malicious files by sending multipart POST requests with arbitrary filenames and disguised content types.
