CVE-2025-26347 is classified as a critical vulnerability, with a CVSS score of 9.8. This vulnerability allows an unauthenticated remote attacker to edit user permissions via crafted HTTP requests. The flaw is rooted in a missing authentication mechanism for critical functions in the Q-Free MaxTime application, specifically in the "maxprofile/menu/routes.lua" file for versions less than or equal to 2.11.0. Organizations using this software must recognize the serious implications of this vulnerability, as it poses significant risks to user data and system integrity.
The risk to organizations includes the ability for attackers to manipulate user permissions without authentication, which could lead to unauthorized access to sensitive data and functionalities. Given the critical nature of this vulnerability and its exploitation potential, organizations should prioritize patching immediately.
Currently, there is no known exploit in the wild, and no public proof of concept has been confirmed. However, the lack of authentication for critical functions makes this vulnerability particularly concerning. Organizations are strongly advised to assess their exposure to this vulnerability and take necessary steps to mitigate any risks.
Given the severity of the vulnerability, organizations should address this issue promptly in their patch cycle to prevent potential exploitation and safeguard their systems.
Vulnerability Details
The official description of CVE-2025-26347 states that it involves a CWE-306 "Missing Authentication for Critical Function" in the Q-Free MaxTime application. The vulnerability affects versions less than or equal to 2.11.0, allowing unauthenticated remote attackers to manipulate user permissions. This critical flaw was published on February 12, 2025, and is classified with a high impact on confidentiality, integrity, and availability.
Technical Analysis
The root cause of this vulnerability stems from a lack of authentication checks for critical functions within the application. Attackers can exploit this weakness through crafted HTTP requests, which may allow them to change user permissions without any prior authentication. The attack vector is classified as network-based, and the attack complexity is low, meaning that even less-skilled attackers could potentially exploit this vulnerability.
No privileges are required to exploit this vulnerability, and user interaction is not necessary. The impacts include high confidentiality, integrity, and availability risks, making this a significant concern for organizations utilizing the affected software.
Risk & Impact Analysis
The deployment risk associated with CVE-2025-26347 is substantial, particularly for organizations that rely on Q-Free MaxTime for operational functionalities. Attackers leveraging this vulnerability could gain unauthorized access to sensitive user data, significantly affecting the integrity of the application.
Organizations should consider the blast radius of this vulnerability, as it could affect multiple user accounts simultaneously, leading to widespread unauthorized access. Given the critical CVSS score, this vulnerability should be prioritized in any immediate patching efforts, reflecting the urgency for organizations to address it.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerable versions of Q-Free MaxTime are all versions prior to 2.11.0. Organizations using this application must ensure they are running a patched version to mitigate this critical vulnerability.
Mitigation & Remediation
Organizations must urgently update their Q-Free MaxTime installation to version 2.11.1 or later to remediate this vulnerability. If immediate patching is not possible, implementing robust network controls to restrict access to the application may serve as a temporary workaround.
Furthermore, organizations should consider conducting a thorough security review of their environments, including a penetration testing engagement to identify any weaknesses that may be exploited.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual HTTP requests targeting the maxprofile/menu/routes.lua path. Behavioral anomalies, such as unexpected changes in user permissions, should also be investigated.
AppSecure Threat Intelligence Insight
CVE-2025-26347 reflects a broader trend in security where misconfigurations and lack of authentication for critical functions have led to severe vulnerabilities. Security teams should learn from this incident to prioritize authentication mechanisms in their applications and conduct regular security assessments.
For organizations looking to enhance their security posture, implementing a comprehensive vulnerability management program can significantly help in identifying and remediating vulnerabilities before they can be exploited.
Additionally, employing best practices in penetration testing methodology can provide proactive insights into potential vulnerabilities within your systems.
Finally, as organizations continue to adopt complex architectures with critical functionalities, it’s essential to integrate security at the development stage to prevent similar vulnerabilities in the future.
