CVE-2025-26339 is a critical vulnerability affecting Q-Free MaxTime software versions less than or equal to 2.11.0. This vulnerability allows unauthenticated remote attackers to affect the device's confidentiality, integrity, or availability through crafted HTTP requests. With a CVSS score of 9.8, this vulnerability poses severe risks to organizations, making immediate remediation imperative.
The attack vector is network-based, requiring no privileges or user interaction. The low complexity of the attack makes it even more concerning, as it can easily be exploited by malicious actors. Given the potential impact on confidentiality, integrity, and availability, organizations are urged to address this vulnerability in their patch cycle.
Currently, there is no known public exploit for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, the lack of an exploit does not diminish its severity, and organizations should not become complacent.
Organizations should prioritize patching immediately to mitigate the risks associated with CVE-2025-26339. Implementing robust security measures and monitoring network traffic can help detect any attempts to exploit this vulnerability.
Vulnerability Details
CVE-2025-26339 is classified as a CWE-306 "Missing Authentication for Critical Function" vulnerability found in the maxtime/handleRoute.lua component of Q-Free MaxTime. The vulnerability allows an unauthenticated remote attacker to affect the device confidentiality, integrity, or availability in multiple unspecified ways via crafted HTTP requests. Officially published on February 12, 2025, it remains critical due to its CVSS score of 9.8, reflecting high potential impacts.
Technical Analysis
The root cause of CVE-2025-26339 is the failure to implement proper authentication for critical functions within the software. This oversight allows attackers to send crafted HTTP requests without needing to authenticate, which can lead to unauthorized access and manipulation of sensitive data. The attack vector is network-based, and the attack complexity is low, as no special privileges or user interaction are required. The potential impacts on confidentiality, integrity, and availability are high, making this vulnerability particularly dangerous.
Risk & Impact Analysis
Organizations using Q-Free MaxTime should be acutely aware of the risks associated with CVE-2025-26339. The real-world deployment risk is significant due to the critical nature of the vulnerability and its ability to impact device confidentiality, integrity, and availability. The blast radius potential is wide, as an attacker could exploit the vulnerability to compromise multiple devices if they are connected to the same network. Urgency is high, as organizations need to patch this vulnerability immediately to prevent unauthorized access and mitigate potential data breaches.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of Q-Free MaxTime prior to version 2.11.0 are affected by this vulnerability. Organizations should ensure they are running the latest version to mitigate risks associated with CVE-2025-26339.
Mitigation & Remediation
To address CVE-2025-26339, organizations should apply the latest patches and updates from Q-Free. If a patch is not available, consider implementing workarounds such as restricting access to the vulnerable component and monitoring HTTP requests for anomalous behavior. Configuration hardening, network controls, and continuous monitoring of system logs are critical to mitigate the risks associated with this vulnerability. Organizations should validate remediation through continuous penetration testing to identify similar weaknesses.
Detection Guidance
Organizations should monitor logs for any unauthorized access attempts, particularly focusing on unusual patterns in HTTP requests. Behavioral anomalies such as unexpected changes in application behavior or network traffic should be investigated promptly. Additionally, network signatures indicative of exploitation attempts should be established to aid in detection.
AppSecure Threat Intelligence Insight
CVE-2025-26339 highlights the importance of implementing proper authentication mechanisms in software applications. The vulnerability reflects a trend where critical functions lack adequate authentication, leading to severe security risks. Security teams should learn from this incident to prioritize secure coding practices and regular security assessments. Organizations can benefit from establishing a robust vulnerability management program and adopting a proactive approach to security through penetration testing and AI security best practices to enhance their overall security posture.
