Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2025-65287

Severity Medium
Score 4.3/10

Summary

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.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
