CVE-2026-43945

frangoteam · FUXA

FUXA contains multiple vulnerabilities including code injection and authentication bypass, allowing unauthenticated attackers to compromise the system.

Executive summary

Unauthenticated attackers can achieve full system compromise in FUXA via code injection and authentication bypass vulnerabilities.

Vulnerability

This issue encompasses improper control of code generation and authentication bypass mechanisms, which allow unauthenticated remote attackers to execute arbitrary code or bypass security controls.

Business impact

Successful exploitation allows an attacker to gain full control over the FUXA process visualization environment, potentially leading to unauthorized manipulation of industrial controls or data exfiltration. Given the high CVSS score of 8.9, this vulnerability poses a severe risk to operational integrity and system availability.

Remediation

Immediate Action: Update the FUXA software to version 1.3.1 or later.

Proactive Monitoring: Monitor network traffic and server access logs for unusual patterns, specifically looking for attempts to interact with administrative endpoints or unauthorized code execution signatures.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block malicious payloads associated with code injection attempts.

Exploitation status

Public Exploit Available: No

Analyst recommendation

The severity of this vulnerability necessitates immediate action to prevent potential remote code execution. System administrators must prioritize upgrading to version 1.3.1 to eliminate the underlying flaws.
