Overview
The cybersecurity landscape is a minefield of potential threats and vulnerabilities, and one such vulnerability is the CVE-2025-49448. This vulnerability, identified as a ‘Path Traversal’ type, is found in the software FW Food Menu developed by Fastw3b LLC. Path Traversal vulnerabilities, if exploited, can lead to unauthorized access to files and data, potentially allowing cybercriminals to uncover sensitive information or even gain control of the system. This particular vulnerability affects all versions of the FW Food Menu software up to and including 6.0.0, thus posing a significant risk to any organization that uses this version of the software.

How the Exploit Works
The CVE-2025-49448 exploit takes advantage of a flaw in the way FW Food Menu handles file and directory paths. An attacker can manipulate the path input to move outside of the intended directory structure, potentially accessing sensitive files or directories. This is commonly achieved through the use of special sequences that represent relative path navigation (such as “../” to move up one directory). If successful, the attacker could potentially access, modify, or delete sensitive files, leading to system compromise or data leakage.
Conceptual Example Code
Here is a conceptual example of a HTTP request that exploits the vulnerability:
GET /fw-food-menu/?file=../../../etc/passwd HTTP/1.1
Host: vulnerable-website.comIn this example, the `../../../etc/passwd` part of the request is an attempt to navigate to the `etc/passwd` file, a critical file in Linux-based systems that contains user account information. If the software is vulnerable, the server would return the content of this file, exposing sensitive information to the attacker.
Mitigation
To protect against this vulnerability, users of FW Food Menu should immediately apply the vendor-supplied patch. If a patch is not available or cannot be applied immediately, users should consider using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block path traversal attempts as a temporary mitigation measure. Regularly updating and patching software is a critical component of maintaining a robust cybersecurity posture.
