CVE-2025-65287: Cdpenergy SNMP Web Pro Firmware

Medium severity, CVSS 4.3. EPSS: 0.8% chance of exploitation in the next 30 days.

An unauthenticated directory traversal vulnerability in cgi-bin/upload.cgi in SNMP Web Pro 1.1 allows a remote attacker to read arbitrary files. The CGI concatenates the user-supplied params directly onto the base path (/var/www/files/userScript/) using memcpy + strcat without validation or canonicalization, enabling ../ sequences to escape the intended directory. The download branch also echoes the unsanitized params into Content-Disposition, introducing header-injection risk.
