CVE-2025-26347 identifies a critical vulnerability in Q-Free MaxTime, specifically within the /menu/routes.lua file. This flaw, classified as a CWE-306 (Missing Authentication for Critical Function), allows an unauthenticated remote attacker to modify user permissions. The vulnerability impacts versions 0 through 2.11.0 of MaxTime, and a patch is available in version 2.11.1.
The impact of CVE-2025-26347 is severe. An attacker exploiting this vulnerability can gain unauthorized access to user accounts and escalate privileges within the MaxTime system. This could lead to complete control over the system's configuration, potentially allowing the attacker to manipulate traffic data, disrupt operations, or exfiltrate sensitive information. The lack of authentication for this critical function means that no prior login or authorization is required to execute the permission modification, dramatically increasing the attack surface. This vulnerability is particularly concerning given the potential for widespread deployment of Q-Free MaxTime systems in traffic management infrastructure.
CVE-2025-26347 was publicly disclosed on 2025-02-12. The vulnerability's criticality (CVSS 9.8) and ease of exploitation (no authentication required) suggest a high probability of exploitation. As of this writing, there are no publicly available proof-of-concept exploits, but the simplicity of the attack vector makes it likely that exploits will emerge. The vulnerability has been added to the CISA KEV catalog, indicating a significant risk to federal information systems.

The primary mitigation for CVE-2025-26347 is to immediately upgrade Q-Free MaxTime to version 2.11.1 or later. If upgrading is not immediately feasible due to compatibility concerns or system downtime requirements, consider implementing strict network segmentation to isolate MaxTime systems from untrusted networks. Review and restrict access to the /menu/routes.lua endpoint using a web application firewall (WAF) or proxy server, blocking any unauthenticated requests. Monitor system logs for suspicious activity, particularly attempts to modify user permissions. After upgrading, confirm the fix by attempting to access the /menu/routes.lua endpoint without authentication and verifying that access is denied.
Update MaxTime to a version later than 2.11.0. This will correct the missing authentication for critical functions and prevent unauthenticated remote attackers from editing user permissions. Refer to the vendor's website for the latest version and upgrade instructions.
