CVE-2025-26361: Critical Vulnerability in Q-Free MaxTime

CVE-2025-26361 is a critical vulnerability affecting Q-Free MaxTime versions 2.11.0 and earlier. The vulnerability is categorized as a CWE-306 "Missing Authentication for Critical Function," which enables unauthenticated remote attackers to execute a factory reset on the device by sending specially crafted HTTP requests. This flaw presents a significant risk as it can lead to unauthorized control over the affected devices.

With a CVSS score of 9.1, organizations should understand the severity of this vulnerability. The ability for attackers to reset devices without authentication poses a direct threat to the integrity and availability of the systems relying on Q-Free MaxTime. It is crucial for security teams to act promptly to address the risk associated with this vulnerability.

The exploitation status indicates that there are currently no known public exploits or proof-of-concept code available. However, given the nature of this vulnerability, organizations should not become complacent. The potential impact of a successful exploit necessitates immediate attention and remediation efforts.

Organizations must prioritize patching this vulnerability immediately to safeguard their systems from potential unauthorized access and control.

As this vulnerability is classified as critical, security teams should ensure that their incident response plans are updated and that they are prepared to address any attempts to exploit this weakness.

Vulnerability Details

The official CVE description states that this vulnerability allows an unauthenticated remote attacker to perform a factory reset on Q-Free MaxTime devices through crafted HTTP requests. The vulnerability is present in the maxprofile/setup/routes.lua file for all versions up to and including 2.11.0.

The CVSS score of 9.1 indicates a critical severity level, primarily due to the potential for high impact on both integrity and availability of the affected systems. The attack vector is classified as network-based, with low complexity and no privileges required for exploitation.

Technical Analysis

The root cause of this vulnerability lies in the lack of authentication controls for critical functions within the application. By failing to enforce authentication, the system allows any user to access sensitive operations, such as device resets.

The attack vector for this vulnerability is network-based, meaning that an attacker can exploit it remotely without physical access to the device. The complexity of the attack is low, as it requires no special conditions or user interaction. Additionally, no privileges are required to carry out the attack.

In terms of impact, the vulnerability has no confidentiality impact, but it does pose significant risks to the integrity and availability of the affected systems. Successful exploitation could lead to unauthorized modifications and disruptions in service.

Risk & Impact Analysis

The real-world risk of this vulnerability is substantial. Organizations using Q-Free MaxTime systems may face severe disruptions, including the loss of control over critical infrastructure. The ability for an attacker to reset devices remotely can lead to operational downtime and potential financial loss.

The urgency for addressing this vulnerability is critical. With the CVSS score indicating high severity, organizations must implement mitigation strategies immediately. The potential blast radius of this vulnerability extends to all devices running the affected software, emphasizing the need for swift action.

Organizations should prioritize patching immediately to prevent unauthorized access and ensure the integrity of their systems. Failure to act could result in significant consequences, including data breaches and prolonged service outages.

Exploitation Status

Affected Versions

The vulnerable versions of Q-Free MaxTime include all releases up to and including version 2.11.0. Organizations are advised to review their systems and ensure that they are not running these affected versions without appropriate mitigations.

Mitigation & Remediation

Organizations should apply the latest patches provided by Q-Free to remediate this vulnerability. If a patch is not available, it is essential to implement network controls to restrict access to the affected devices and monitor for any unauthorized attempts to access critical functions.

Furthermore, organizations can benefit from conducting a thorough security assessment, including a review of device configurations and access controls, to enhance overall security posture.

Penetration testing can also help identify potential vulnerabilities in configuration and help organizations mitigate risks effectively.

Detection Guidance

To detect potential exploitation attempts, organizations should monitor logs for unusual patterns, such as repeated HTTP requests targeting the maxprofile/setup/routes.lua endpoint. Additionally, implementing alerts for unauthorized device resets can provide early warning signs of potential attacks.

Network signatures that identify malicious traffic patterns can also be useful in detecting attempts to exploit this vulnerability.

AppSecure Threat Intelligence Insight

The long-term significance of CVE-2025-26361 highlights a persistent issue in embedded systems and IoT devices where authentication controls are often overlooked. This trend underscores the need for organizations to prioritize secure coding practices in their development lifecycle.

Organizations must remain vigilant and conduct regular security assessments to identify and address similar vulnerabilities proactively.

Implementing a robust vulnerability management program is crucial to maintaining security and managing risks effectively.

Additionally, organizations should consider leveraging continuous security testing methodologies to ensure that vulnerabilities are identified and remediated in a timely manner.

Following a structured penetration testing methodology can further bolster an organization's defenses against such vulnerabilities.
