Jun 26, 2025An unauthenticated file upload vulnerability exists in the Fanwei E-Office <= v9.4 web management interface.CVE-2025-34046 · Other software · Shanghai Fanwei Network Technology · reported by VulnCheckCritical 10
An unauthenticated file upload vulnerability exists in the Fanwei E-Office <= v9.4 web management interface. The vulnerability affects the /general/index/UploadFile.php endpoint, which improperly validates uploaded files when invoked with certain parameters (uploadType=eoffice_logo or uploadType=theme). An attacker can exploit this flaw by sending a crafted HTTP POST request to upload arbitrary files without requiring authentication. Successful exploitation could enable remote code execution on the affected server, leading to complete compromise of the web application and potentially the underlying system. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-05 UTC.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
