CVE-2026-3826

WellChoose · IFTOP

A Local File Inclusion (LFI) vulnerability in WellChoose IFTOP allows unauthenticated remote attackers to execute arbitrary code on the server.

Executive summary

WellChoose IFTOP contains a critical vulnerability that allows unauthenticated remote attackers to include local files and execute arbitrary code, leading to a complete server compromise.

Vulnerability

This vulnerability is a Local File Inclusion (LFI) flaw. An unauthenticated remote attacker can manipulate input to include files from the local server. By including specific system files or uploaded malicious content, the attacker can transition from file inclusion to arbitrary code execution (RCE) on the host server.

Business impact

The CVSS score of 9.8 underscores the extreme risk associated with this flaw. A successful exploit allows an attacker to gain full control of the server, leading to the theft of sensitive data, service outages, and the use of the server as a pivot point for further attacks within the network.

Remediation

Immediate Action: Update WellChoose IFTOP to the latest version immediately to patch the LFI vulnerability.

Proactive Monitoring: Monitor web server logs for directory traversal patterns (e.g., ../..) and unusual file access requests.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules specifically designed to detect and block Local File Inclusion and directory traversal attacks.

Exploitation status

Public Exploit Available: No

Analyst recommendation

Immediate patching is required to protect servers running WellChoose IFTOP. Because the vulnerability is unauthenticated and remote, the window for exploitation is wide. Organizations should prioritize this update and review their web application security posture.
